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.
