Many people believe that theological study holds little value. They say, “I don’t need theology; I just need to know Jesus.” Yet theology is unavoidable for every Christian. It is our attempt to understand the truth that God has revealed to us—something every Christian does. So it is not a question of whether we are going to engage in theology; it is a question of whether our theology is sound or unsound. It is important to study and learn because God has taken great pains to reveal Himself to His people. He gave us a book, one that is not meant to sit on a shelf pressing dried flowers, but to be read, searched, digested, studied, and chiefly to be understood.
An important text in the writings of the Apostle Paul is found in his second letter to Timothy: “All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work”(2 Tim. 3:16–17). That text should put an end to claims that we do not need doctrine or that doctrine has no value. There is profit from a careful study of the Bible. Because the Bible is inspired by almighty God, it gives us a valuable and profitable asset, and that asset is doctrine.
The Bible is profitable also for reproof. The academic world devotes much energy to biblical criticism, sometimes called higher criticism, which is an analytical critique of Scripture. However, the biblical criticism in which we ought to engage renders us the object rather than the subject of the criticism. In other words, the Bible criticizes us. When we come to the Word of God, the Word of God exposes our sin. The biblical doctrine of man includes us, as does the biblical doctrine of sin, and we are reproved for our sinfulness when we come to the text of Scripture. We may not listen to the criticism of our peers, but we are wise to heed the criticism of God as it comes to us in sacred Scripture.
Scripture is also profitable for correction from both false living and false belief. Some time ago, at the request of a friend, I read a New York Times best seller about how to become a medium and communicate with the dead. I got about halfway through the book and had to stop reading. There was so much spiritual filth in that book, so much falsehood, that those with even a simple understanding of the law of God in the Old Testament would have been able to detect the lies. Such is the profit of correction from false teaching and false living that we can gain from Scripture.
Finally, Scripture is profitable “for training in righteousness, that the man of God may be complete, equipped for every good work.” The purpose of theology is not to tickle our intellects but to instruct us in the ways of God, so that we can grow up into maturity and fullness of obedience to Him. That is why we engage in theology.
