Knowing what orthodox, biblical Christianity teaches is not difficult. In fact, even unbelievers can know what the Bible says. But head knowledge is not enough. Doctrine must penetrate our hearts so that we are convicted to repent of sin and seek to do what is good. As we study the things of the Lord, let us continually ask Him to use what we study to bring us to repentance and to establish our hearts with the desire and understanding needed to do what He seeks from us.
