Man does not change in order to be saved, but true salvation always brings about an evident change in the life of the new believer. Perhaps the change is less noticeable in some new believers and more noticeable in others; however, no change means no salvation. The change is not always an immediate outward change because it involves a change of the inward nature. A person who trusts Christ for salvation becomes a new creature (Galatians 6:15). It might be best to consider how this could be likened to a dog (Matthew 15:26-27) becoming a sheep (John 10:16). A new man now dwells within the new Christian to help combat and defeat the old sinful nature (Ephesians 4:22-24). Salvation is not merely the turning over of a new leaf; it is a new birth (John 3:3) where one is passed from spiritual death to spiritual life (John 5:24).
Paul served as Timothy’s mentor. In fact, Paul referred to Timothy as his “son in the faith” (1 Timothy 1:2). As Timothy’s mentor, Paul gave Timothy truths with the intent that he would pass along those teachings to other believers. Though there are certainly variations of what should be taught, Paul laid out two foundational categories when he mentioned “words of faith and of good doctrine” (1 Timothy 4:6). Though specifics are given in the epistles of First and Second Timothy and Titus, every teaching should reflect the categories set forth by the apostle Paul. Even practical teaching ought to be based upon the words of God, as some teachings are good (2 Thessalonians 2:15), and some are bad (Matthew 15:9). Every teacher should teach with hopes of eventually learning from his students when they too become the teachers.
