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.
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.
