Why Should I Study Theology? A Baptist Theological Perspective
Theology, at its core, is the study of God—His nature, His works, His relation to the world, and the truths He has revealed in Scripture. It is the disciplined and prayerful pursuit of knowing God more deeply and living in accordance with His will. The word theology itself derives from the Greek words theos (God) and logos (word, study), meaning “the study of God.” For Christians, theology is not a mere academic exercise; it is an act of worship, a means of spiritual growth, and an essential component of faithful Christian living.
The study of theology addresses the foundational questions of life: Who is God? Why are we here? What is the purpose of existence? In contrast to disciplines such as science, which seek to understand the natural world through observation and experimentation, theology delves into divine revelation, relying on the Bible as the inspired, inerrant, and sufficient Word of God (2 Timothy 3:16–17; 2 Peter 1:20–21). Theology is the pursuit of ultimate truth, as revealed by the Creator of all things.
The Benefits of Studying Theology for Christians
1. To Know God and Gain Wisdom
Theology equips believers to know God as He has revealed Himself in His Word. Proverbs 2:6 declares, “For the Lord gives wisdom; from His mouth come knowledge and understanding” (NKJV). True wisdom begins with the fear of the Lord, as Proverbs 9:10 reminds us: “The fear of the Lord is the beginning of wisdom, and the knowledge of the Holy One is understanding” (NKJV). The study of theology is a God-ordained means of growing in this wisdom.
Through theology, believers come to know God’s attributes—His holiness (Isaiah 6:3), love (1 John 4:8), justice (Deuteronomy 32:4), omniscience (Psalm 139:1–6), omnipotence (Revelation 19:6), and sovereignty (Romans 8:28). Theology also deepens our understanding of God’s works in creation, providence, and redemption. This knowledge leads to a richer worship of God and a greater awe of His majesty.
2. To Grow Spiritually and Be Transformed
Theology is essential for spiritual growth and sanctification. Jesus prayed, “Sanctify them by Your truth. Your word is truth” (John 17:17, NKJV). The study of theology involves digging deeply into the Scriptures, which are the primary means of sanctification. As believers study God’s Word, they are transformed by the renewing of their minds (Romans 12:2) and conformed to the image of Christ (2 Corinthians 3:18).
Second Peter 1:3 assures us that “His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue” (NKJV). Theology provides the framework for understanding this knowledge and applying it to daily life.
3. To Strengthen Faith
Faith is built upon knowledge, and theology provides the foundation for a robust and unwavering faith. Romans 10:17 teaches, “So then faith comes by hearing, and hearing by the word of God” (NKJV). Theology strengthens faith by grounding it in the truths of Scripture and enabling believers to stand firm against doubt, false teachings, and cultural pressures.
4. To Discern Truth from Error
In a world filled with false ideologies and competing worldviews, theology equips believers to discern truth from error. Psalm 119:160 affirms, “The entirety of Your word is truth, and every one of Your righteous judgments endures forever” (NKJV). By studying theology, Christians develop the ability to evaluate doctrines, philosophies, and cultural trends in light of God’s Word. This discernment protects the church from heresy and ensures faithfulness to the gospel.
Paul exhorts Timothy, “Hold fast the pattern of sound words which you have heard from me, in faith and love which are in Christ Jesus” (2 Timothy 1:13, NKJV). Theological study enables believers to hold fast to sound doctrine and reject the counterfeit teachings that threaten the church.
5. To Equip for Ministry and Service
Theology prepares believers for effective ministry and service in the body of Christ. Paul reminds Timothy, “All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work” (2 Timothy 3:16–17, NKJV). Theology equips pastors, teachers, and laypeople alike to proclaim the gospel, defend the faith, and edify the church.
6. To Foster Worship and Love for God
Theology leads to doxology—worship. The more believers know about God, the more they will love and glorify Him. As Jesus said, “You shall love the Lord your God with all your heart, with all your soul, and with all your mind” (Matthew 22:37, NKJV). The study of theology engages the mind in worship, deepening the believer’s love for God and fueling a life of obedience and devotion.
The Broader Scope of Theology: Understanding World Religions and Apologetics
1. Understanding Other Religions
The study of theology often includes the study of other religions. Understanding the beliefs and practices of other faiths enables Christians to engage in meaningful dialogue and share the gospel effectively. Peter exhorts believers to “always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear” (1 Peter 3:15, NKJV). Knowledge of world religions helps Christians build bridges of understanding and address the questions and objections of unbelievers.
2. Defending the Faith
Theology is foundational to apologetics, the defense of the Christian faith. Paul writes, “For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God” (2 Corinthians 10:4–5, NKJV). Through theology, Christians are equipped to refute falsehoods, defend biblical truth, and present the gospel with clarity and conviction.
Conclusion: The Call to Study Theology
The study of theology is a sacred privilege and a vital responsibility for every believer. It deepens our knowledge of God, strengthens our faith, equips us for ministry, and fosters a life of worship and obedience. Far from being an abstract or academic pursuit, theology is a means of knowing and loving the God who has revealed Himself in Jesus Christ.
Paul’s prayer in Philippians 1:9–11 captures the heart of theological study: “And this I pray, that your love may abound still more and more in knowledge and all discernment, that you may approve the things that are excellent, that you may be sincere and without offense till the day of Christ, being filled with the fruits of righteousness which are by Jesus Christ, to the glory and praise of God” (NKJV).
To study theology is to pursue the knowledge of God for the glory of God. It is a journey that transforms the mind, renews the heart, and equips the believer to live faithfully in a fallen world while awaiting the return of Christ. As Jesus said, “This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent” (John 17:3, NKJV).
