Isaiah Chapter 58
Isaiah 58, The Blessing of True Worship
A. The LORD Exposes the Shallow Worship of His People
1. Isaiah 58:1-3a, God’s People Ask, “Why Do Our Prayers Go Unanswered?”
Isaiah 58:1-3, “Cry aloud, spare not, lift up thy voice like a trumpet, and shew my people their transgression, and the house of Jacob their sins. Yet they seek me daily, and delight to know my ways, as a nation that did righteousness, and forsook not ordinance of their God: they ask me ordinances justice, they take delight in approaching to God. Wherefore have we fasted, say they, and thou seest not? wherefore have we afflicted our soul, and thou takest no knowledge?”
The chapter begins with a command to the prophet, “Cry aloud, spare not.” Isaiah is not told to whisper, soften, or politely suggest correction. He is commanded to lift up his voice “like a trumpet.” A trumpet was used to awaken, warn, summon, and announce. The issue before Judah was not minor. God’s people were practicing religion while living in sin, and the prophet was required to expose it plainly.
The LORD says, “shew my people their transgression, and the house of Jacob their sins.” This is important because God still calls them “my people,” yet He also calls out their transgression. Covenant privilege did not excuse covenant rebellion. Religious identity did not cancel moral accountability. The house of Jacob still belonged to God by covenant, but they were guilty of sin and needed to be confronted.
This is a necessary part of faithful preaching and teaching. A man of God cannot only comfort. He must also warn. 2 Timothy 4:2, “Preach word, be instant in season, out season, reprove, rebuke, exhort with all longsuffering and doctrine.” Biblical ministry includes reproof and rebuke, not because the preacher enjoys confrontation, but because God’s people need truth more than flattery.
The LORD then describes the outward appearance of Judah’s religion. “Yet they seek me daily, and delight to know my ways.” On the surface, they looked serious. They sought God daily. They delighted to know His ways. They appeared as “a nation that did righteousness.” They asked for the ordinances of justice and took delight in approaching God. If a man only looked at their religious activity, he might assume Judah was spiritually healthy.
But this was only a veneer. They had the appearance of devotion without the reality of obedience. They knew how to approach God outwardly, but they did not walk with Him honestly. They were religious, but they were not repentant. They wanted God’s blessing without God’s correction. They wanted answered prayer without transformed lives.
This is why they asked, “Wherefore have we fasted, say they, and thou seest not?” They were offended that God did not seem impressed with their fasting. They believed their religious discipline obligated God to answer them. Their complaint was essentially, “Lord, we fasted. We afflicted our souls. Why have You not noticed? Why have You not responded?”
Their problem was not that God failed to see. Their problem was that they failed to see themselves truthfully. They assumed that religious activity could compensate for disobedience. They believed fasting could cover exploitation, strife, pride, and injustice. But God does not accept religious performance as a substitute for repentance.
1 Samuel 15:22, “And Samuel said, Hath LORD as great delight in burnt offerings and sacrifices, as in obeying voice LORD? Behold, to obey is better than sacrifice, and to hearken than fat rams.”
The issue was not fasting itself. Fasting can be a godly discipline when joined with humility, repentance, prayer, and dependence upon God. The issue was hypocritical fasting. Judah fasted, but their hearts were wrong. They wanted God to respond to ritual while they ignored righteousness.
2. Isaiah 58:3b-5, God Exposes the Shallow Worship of His People
Isaiah 58:3-5, “Behold, in day fast ye find pleasure, and exact all your labours. Behold, ye fast for strife and debate, and to smite with fist wickedness: ye shall not fast as ye do this day, to make your voice to be heard on high. Is it such fast that I have chosen? day for man to afflict his soul? is it to bow down his head as bulrush, and to spread sackcloth and ashes under him? wilt thou call this fast, and acceptable day to LORD?”
The LORD now exposes the reality behind their religious image. “Behold, in day fast ye find pleasure, and exact all your labours.” Even on the day of fasting, they pursued their own pleasure and exploited their workers. They afflicted their own souls outwardly, but they afflicted others unjustly. Their fasting did not make them more merciful, humble, righteous, or obedient. Therefore, God rejected it.
This is a critical principle. Worship that does not affect conduct is hollow. Religious observance cannot be separated from righteousness in ordinary life. A man cannot claim to humble himself before God while abusing those under his authority. He cannot claim spiritual devotion while cheating employees, neglecting family, using people, or operating with cruelty.
James 5:4, “Behold, hire labourers who have reaped down your fields, which is of you kept back by fraud, crieth: and cries them which have reaped are entered into ears Lord sabaoth.”
God hears the prayers of the oppressed, not merely the prayers of the religiously active. Judah fasted, but the laborers they exploited cried out, and God heard that also.
Adam Clarke’s old warning against religious hypocrisy in the face of slavery fits the moral weight of this passage. He rebuked any nation that would pretend to fast or worship God while trafficking in the souls, blood, and bodies of men. His point was sound. Men cannot cover public wickedness with religious language. To profess faith while continuing in open injustice is to deepen guilt, not remove it.
The LORD continues, “Behold, ye fast for strife and debate, and to smite with fist wickedness.” Their fasting was not producing peace, repentance, or humility. It was connected to strife, argument, and aggression. They were using religion to strengthen selfish ambition. They wanted God to help them win disputes, defeat enemies, and advance their own cause.
This is one of the ugliest forms of religion, prayer and fasting used to baptize pride. A man may pray, but if his prayer is driven by bitterness, revenge, greed, or domination, he is not praying in the Spirit of God. He is trying to enlist God in his own sin.
James 4:3, “Ye ask, and receive not, because ye ask amiss, that ye may consume upon your lusts.”
God says, “ye shall not fast as ye do this day, to make your voice to be heard on high.” They wanted their voice heard in heaven, but God refused the terms of their worship. Fasting does not force God’s hand. Religious discipline does not manipulate the Almighty. God is not impressed by hunger if the heart remains proud. He is not moved by sackcloth if the life remains wicked.
The LORD asks, “Is it such fast that I have chosen?” This question cuts through the entire performance. Their fasting had the external signs of humility, bowing the head like a bulrush, spreading sackcloth and ashes, afflicting the soul. But God asks whether that is truly the fast He desires. The answer is no, not when those outward signs are detached from repentance and righteousness.
The people of Isaiah’s day had the same problem as the Pharisees in the days of Christ. They trusted in visible religious discipline while neglecting the inner reality. Jesus exposed this directly.
Luke 18:9-14, “And he spake this parable unto certain which trusted in themselves that they were righteous, and despised others: Two men went up into temple to pray, one Pharisee, and other publican. Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men, extortioners, unjust, adulterers, or even as this publican. I fast twice in week, I give tithes all that I possess. And publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me sinner. I tell you, this man went down to his house justified rather than other: for every one that exalteth himself shall be abased, and he that humbleth himself shall be exalted.”
The Pharisee fasted, but his fasting fed pride. The publican did not boast of religious discipline. He humbled himself before God and cried for mercy. God received the humbled sinner, not the religious performer.
This does not mean fasting is wrong. Fasting can be powerful when joined with true faith and dependence upon God.
Matthew 17:21, “Howbeit this kind goeth not out but by prayer and fasting.”
The issue is not whether fasting should exist. The issue is whether fasting is joined to real repentance, obedience, and humility. Jesus rebuked empty religious rituals, but He did not command His people to abandon all visible obedience. He said the weightier matters must not be neglected.
Matthew 23:23, “Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe mint and anise and cummin, and have omitted weightier matters law, judgment, mercy, and faith: these ought ye to have done, and not to leave other undone.”
The answer to hypocrisy is not to stop obeying God outwardly. The answer is to obey God outwardly from a heart that is right inwardly.
B. The Character and Blessings of True Worship
1. Isaiah 58:6-7, The Kind of Worship and Fasting Most Acceptable to God
Isaiah 58:6-7, “Is not this fast that I have chosen? to loose bands wickedness, to undo heavy burdens, and to let oppressed go free, and that ye break every yoke? Is it not to deal thy bread to hungry, and that thou bring poor that are cast out to thy house? when thou seest naked, that thou cover him, and that thou hide not thyself from thine own flesh?”
The LORD now defines the fast He has chosen. True fasting is not merely abstaining from food. It is humbling oneself before God in a way that produces righteousness toward others. God says true fasting includes “to loose bands wickedness, to undo heavy burdens, and to let oppressed go free, and that ye break every yoke.”
The first requirement is to stop doing evil. If Judah wanted to fast acceptably, they had to stop oppressing people. They had to stop binding others with wickedness. They had to remove heavy burdens. They had to release the oppressed and break yokes. A fast that leaves oppression untouched is not pleasing to God.
This applies to every sphere of authority. Employers must not exploit workers. Leaders must not use people for gain. Fathers must not rule their homes with cruelty. Churches must not burden people with man made religion while neglecting truth, mercy, and holiness. A man cannot worship God rightly while knowingly crushing people under his authority.
Micah 6:8, “He hath shewed thee, O man, what is good, and what doth LORD require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?”
True worship includes justice, mercy, and humility. It is not sentimental religion. It is obedience that reaches into the way a man treats people.
The LORD then moves from ceasing evil to doing good. “Is it not to deal thy bread to hungry, and that thou bring poor that are cast out to thy house?” God’s people were not merely to stop oppression. They were to practice compassion. They were to feed the hungry, shelter the poor, cover the naked, and refuse to hide from their own flesh.
This means true worship has both negative and positive obedience. A man must stop doing wickedness, but he must also begin doing righteousness. It is not enough to say, “I do not hurt anyone.” The question is also, “Whom have I helped? Whom have I served? Whom have I strengthened? Whom have I covered?”
James 2:15-17, “If brother or sister be naked, and destitute daily food, And one you say unto them, Depart in peace, be ye warmed and filled, notwithstanding ye give them not those things which are needful to body, what doth it profit? Even so faith, if it hath not works, is dead, being alone.”
God’s command to “hide not thyself from thine own flesh” means they were not to ignore the needs of their own people, their own family, their own covenant community, and their fellow man. There is a kind of religious man who can talk theology while avoiding responsibility. God rejects that hypocrisy. True worship faces need and acts.
2. Isaiah 58:8-12, The Blessings God Promises for the True Worshipper
Isaiah 58:8-12, “Then shall thy light break forth as morning, and thine health shall spring forth speedily: and thy righteousness shall go before thee, glory LORD shall be thy rereward. Then shalt thou call, and LORD shall answer, thou shalt cry, and he shall say, Here I am. If thou take away from midst thee yoke, putting forth finger, and speaking vanity, And if thou draw out thy soul to hungry, and satisfy afflicted soul, then shall thy light rise in obscurity, and thy darkness be as noonday: And LORD shall guide thee continually, and satisfy thy soul in drought, and make fat thy bones: and thou shalt be like watered garden, and like spring water, whose waters fail not. And they that shall be of thee shall build old waste places: thou shalt raise up foundations many generations, and thou shalt be called, repairer breach, restorer paths to dwell in.”
God now gives the blessings promised to those whose worship is sincere and whose fasting is joined with righteousness. “Then shall thy light break forth as morning.” When God’s people stop hiding sin behind religion and begin walking in true repentance, light breaks forth. Darkness is removed. Confusion lifts. Spiritual life begins to shine again.
God says, “and thine health shall spring forth speedily.” This speaks of restoration, healing, and renewal. Sin damages the soul. Hypocrisy dries up spiritual vitality. True repentance brings healing because fellowship with God is restored.
Psalm 32:3-5, “When I kept silence, my bones waxed old through my roaring all day long. For day and night thy hand was heavy upon me: my moisture is turned into drought summer. Selah. I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto LORD, and thou forgavest iniquity my sin. Selah.”
The LORD promises, “thy righteousness shall go before thee, glory LORD shall be thy rereward.” The word rereward means rear guard. God would surround His obedient people. Righteousness would go before them, and the glory of the LORD would guard behind them. This echoes the Exodus, where God guided and protected Israel.
Exodus 14:19-20, “And angel God, which went before camp Israel, removed and went behind them, and pillar cloud went from before their face, and stood behind them: And it came between camp Egyptians and camp Israel, and it was cloud and darkness to them, but it gave light by night to these: so that one came not near other all night.”
God’s people are safest when they walk in obedience. The world thinks compromise provides security, but Scripture teaches that righteousness is the true path of divine protection.
The next promise answers the complaint from the beginning of the chapter. “Then shalt thou call, and LORD shall answer, thou shalt cry, and he shall say, Here I am.” Earlier, Judah complained that they fasted and God did not see. God now says that when their worship becomes sincere and their lives become obedient, He will answer. The problem was never that God was deaf. The problem was that sin had corrupted their worship.
Isaiah 59:1-2, “Behold, LORD hand is not shortened, that it cannot save, neither his ear heavy, that it cannot hear: But your iniquities have separated between you and your God, and your sins have hid face from you, that he will not hear.”
The LORD again gives conditions of repentance. “If thou take away from midst thee yoke, putting forth finger, and speaking vanity.” They must remove oppression. They must stop pointing the finger. They must stop speaking wickedness.
The pointing of the finger represents accusation, blame shifting, contempt, and hostility. Instead of examining themselves, they attacked others. This is common in religious hypocrisy. Men often use criticism of others to avoid repentance in themselves.
Matthew 7:3-5, “And why beholdest thou mote that is in thy brother eye, but considerest not beam that is in thine own eye? Or how wilt thou say to thy brother, Let me pull out mote out thine eye, and, behold, beam is in thine own eye? Thou hypocrite, first cast out beam out thine own eye, and then shalt thou see clearly to cast out mote out thy brother eye.”
They also had to stop “speaking vanity.” Wicked speech, empty speech, slander, deceit, and destructive words were incompatible with true worship. The tongue reveals the heart.
James 1:26, “If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man religion is vain.”
Then the LORD commands positive obedience again. “And if thou draw out thy soul to hungry, and satisfy afflicted soul.” This goes beyond giving bread mechanically. They were to extend their soul. That means compassion, personal involvement, sincere care, and sacrificial concern. God is not calling for cold charity that merely checks a box. He is calling for mercy that comes from the heart.
This addresses sins of omission. The people had not only done wrong things, they had failed to do right things. Historic Christian confession rightly recognizes both. Men sin by doing what they ought not to have done, and by leaving undone what they ought to have done. A man can be guilty before God not only because of direct wickedness, but because he ignored clear duties of mercy, justice, prayer, leadership, and love.
James 4:17, “Therefore to him that knoweth to do good, and doeth it not, to him it is sin.”
To the repentant, God promises, “then shall thy light rise in obscurity, and thy darkness be as noonday.” God can make light rise even in dark conditions. He can make the darkest place as bright as noon. This is not superficial optimism. It is divine restoration. When God turns the lights on, darkness cannot keep its power.
The LORD promises, “And LORD shall guide thee continually.” Guidance belongs to those who walk humbly with God. Empty ritual does not guarantee divine direction. The man who wants God’s guidance must seek God with sincerity and obedience.
Proverbs 3:5-6, “Trust in LORD with all thine heart, and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths.”
God also promises to “satisfy thy soul in drought.” This is deep spiritual provision. Drought represents scarcity, difficulty, pressure, and dryness. God does not promise that His people will never pass through drought. He promises satisfaction in drought. This is better than easy circumstances. It is the sustaining grace of God in hard circumstances.
He will also “make fat thy bones.” This speaks of strength, vitality, and inner health. Hypocrisy weakens. Sin dries up the bones. Obedience strengthens the soul.
The image continues, “and thou shalt be like watered garden, and like spring water, whose waters fail not.” A watered garden is fruitful, alive, fragrant, and useful. A spring whose waters do not fail is steady and reliable. This is the life of the true worshipper. He is not merely religious. He is spiritually alive and fruitful.
Psalm 1:1-3, “Blessed is man that walketh not in counsel ungodly, nor standeth in way sinners, nor sitteth in seat scornful. But his delight is in law LORD, and in his law doth he meditate day and night. And he shall be like tree planted by rivers water, that bringeth forth his fruit in his season, his leaf also shall not wither, and whatsoever he doeth shall prosper.”
Finally, God promises kingdom usefulness. “And they that shall be of thee shall build old waste places: thou shalt raise up foundations many generations.” True worshippers become rebuilders. They do not merely complain about ruins. They repair them. They raise foundations. They restore what sin, neglect, and judgment have broken.
The people would be called “repairer breach, restorer paths to dwell in.” This is a noble title. A breach is a break in a wall, a place where enemies can enter and destruction can spread. To repair the breach is to restore protection, order, and safety. To restore paths to dwell in is to make life livable again, to rebuild the ways people can walk securely before God.
This has strong application today. There are breaches everywhere, broken homes, broken churches, broken families, broken moral boundaries, broken communities, broken leadership, and broken understanding of truth. A faithful man does not merely curse the darkness. He repairs what he can under God. He teaches truth, strengthens his household, protects the vulnerable, restores order, and builds for the next generation.
A life right with God is enlightened, guided, satisfied, fruitful, sustained, and productive. It is not shallow religion. It is living fellowship with the LORD that produces visible righteousness.
3. Isaiah 58:13-14, True Sabbath Keeping and the Blessings of It
Isaiah 58:13-14, “If thou turn away thy foot from sabbath, from doing thy pleasure on my holy day, and call sabbath delight, holy LORD, honourable, and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: Then shalt thou delight thyself in LORD, and I will cause thee to ride upon high places earth, and feed thee with heritage Jacob thy father: for mouth LORD hath spoken it.”
The chapter closes by addressing Sabbath keeping. Like fasting, the Sabbath had become another empty religious observance for many in Judah. They may have outwardly recognized the day, but they did not honor the LORD from the heart. God calls them to turn their foot away from the Sabbath, meaning they were to stop trampling His holy day with selfishness and empty routine.
The LORD says they must stop “doing thy pleasure on my holy day.” The Sabbath belonged to God in Israel’s covenant order. It was not merely a day off. It was a day set apart to honor Him, remember His creation, rest in His provision, and recognize His covenant authority.
Exodus 20:8-11, “Remember sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But seventh day is sabbath LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor stranger that is within thy gates: For in six days LORD made heaven and earth, sea, and all that in them is, and rested seventh day: wherefore LORD blessed sabbath day, and hallowed it.”
God commands them to “call sabbath delight, holy LORD, honourable.” True Sabbath keeping was not meant to be a dead burden. It was to be a delight. The people were to love what the day represented, rest in God, honor God, and cease from self directed living. They were to honor Him by “not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words.”
This does not mean that God hated joy. It means that the Sabbath was to be God centered, not self centered. The issue was lordship. Would they order their lives around God’s Word, or would they use even holy things for their own desires?
In light of the New Testament, Christians must handle Sabbath teaching carefully. Israel was commanded to observe the Sabbath as part of the Mosaic covenant. The New Testament teaches that believers in Christ are not under legal obligation to keep the Sabbath day as Israel did.
Colossians 2:16-17, “Let no man therefore judge you in meat, or in drink, or in respect holyday, or new moon, or sabbath days: Which are shadow things to come, but body is of Christ.”
The Sabbath was a shadow. Christ is the substance. The rest signified by the Sabbath is fulfilled in Him. The believer rests not in his own works, but in the finished work of Christ.
Hebrews 4:9-10, “There remaineth therefore rest to people God. For he that is entered into his rest, he also hath ceased from his own works, as God did from his.”
This means the Christian is not justified by Sabbath observance. He does not keep days in order to earn standing with God. His righteousness is in Christ. His rest is in Christ.
Galatians 4:10-11, “Ye observe days, and months, and times, and years. I am afraid you, lest I have bestowed upon you labour in vain.”
At the same time, freedom from the Mosaic Sabbath does not mean believers should despise the principle of rest and worship. God made man with limits. A wise Christian honors the rhythm of work, rest, worship, and renewal. The Lord’s Day, the first day of the week, became the regular day of Christian gathering because of the resurrection of Christ, but it is not a legal Sabbath in the Mosaic sense.
Acts 20:7, “And upon first day week, when disciples came together to break bread, Paul preached unto them, ready to depart morrow, and continued his speech until midnight.”
The important point in Isaiah 58 is that God rejects empty Sabbath keeping just as He rejects empty fasting. Religious abstinence alone does not make a man right with God. It is not enough to say, “I did not eat,” or “I did not work.” God asks deeper questions. Did you honor Me? Did you obey Me? Did you stop oppressing others? Did you feed the hungry? Did you repair the breach? Did your worship produce righteousness?
The promise is beautiful, “Then shalt thou delight thyself in LORD.” The reward for true worship is not merely blessing from the LORD, but delight in the LORD Himself. This is higher than material benefit. The greatest gift God gives is Himself.
Psalm 37:4, “Delight thyself also in LORD, and he shall give thee desires thine heart.”
The LORD also promises, “I will cause thee to ride upon high places earth, and feed thee with heritage Jacob thy father.” This speaks of covenant blessing, security, victory, and inheritance. For Israel, this was connected to the promises given to Jacob and the covenant blessings of the land. God would exalt, sustain, and feed His obedient people.
The chapter ends with certainty, “for mouth LORD hath spoken it.” This is not wishful thinking. It is not religious optimism. It is divine authority. What God speaks is settled. The people may ignore it, but they cannot overturn it. True worship brings blessing. Hypocritical worship brings rebuke. The mouth of the LORD has spoken.
Theological Summary of Isaiah 58
Isaiah 58 exposes the difference between religious performance and true worship. Judah fasted, sought God daily, asked for justice, and appeared to delight in approaching God. Yet their prayers went unanswered because their religion was shallow. They fasted while exploiting workers, striving with others, speaking wickedness, and neglecting the hungry and afflicted.
God does not reject fasting itself. He rejects fasting without repentance. He rejects religious forms that leave sin untouched. True worship stops oppression, breaks yokes, feeds the hungry, shelters the poor, covers the naked, and refuses to hide from duty. The life that pleases God is not defined only by what a man avoids, but by what he does in obedience to the LORD.
The blessings promised are rich. God gives light, healing, righteousness, protection, answered prayer, continual guidance, satisfaction in drought, strength, fruitfulness, and usefulness in rebuilding what has been broken. The true worshipper becomes a repairer of the breach and a restorer of paths to dwell in.
The chapter ends with Sabbath instruction, showing that fasting and Sabbath keeping can both become hollow if separated from the heart of worship. For Israel, Sabbath keeping was covenant obedience. For the Christian, the Sabbath shadow is fulfilled in Christ, who is our rest. Yet the principle remains, God is honored not by empty religious gestures, but by sincere faith, obedient worship, righteous conduct, and delight in the LORD Himself.
