Paul now gives us a creedal statement about the scriptures. He points to four uses. A negative and positive teaching use and a negative and positive life-style use. The Old Testament scriptures are useful to teach sound doctrine and to expose untruth. They are also useful for ethics, correcting evil behavior and training in right behavior.
Biblical truth serves to equip Christian ministers.
Paul now gives his final charge to Timothy. Now comes the charge itself. Timothy is to preach the truths of God's Word at every possible opportunity. Paul warns Timothy of the day that is coming and is in a sense already here, when believers will go after false teachers. These teachers proclaim truths which are to their own liking, rather than Biblical truth.
