Timothy’s church leadership position put him in a role to influence the lives of others. Only the proper conversation could avoid adversely affecting other believers. Furthermore, Timothy was a young man and Paul knew that others might despise him for his youth. Therefore, Paul instructed Timothy how to eliminate this problem. He was to be the right type of an example to the believers. Paul gave Timothy several areas in which to be that example. One of these involved Timothy's conversation. Paul knew that it was important for other people to be able to look at Timothy’s life and glean an idea of what their conversation should resemble. Just as Paul had been an example to Timothy, Timothy was to be an example for others.
A godly mother and grandmother helped raise Timothy by teaching him the truths of God’s word (2 Timothy 1:5; 2 Timothy 3:15). Paul wrote to Timothy specifically warning him in 1 Timothy chapter 4 concerning the dangers of the last days (i.e., the doctrines of devils, fables, and unedifying quarrels). In the midst of these warnings, Paul reminded Timothy to take heed unto himself. Timothy needed to guard against troubles from without while diligently taking care of his own walk with Christ. The Old Testament further reinforces these truths. The children of Israel were told to keep their souls diligently (Deuteronomy 4:9) and Solomon instructed his son to keep his heart “with all diligence” (Proverbs 4:23). Every Christian should carefully and zealously guard his walk with the Lord.
