This life offers only a window of time and opportunity to work for the Lord. Youthfulness and old age both offer their own hindrances to service. In many ways, though not entirely, youth should be spent in learning, middle age in doing, and old age in teaching those who are learning and doing. Many of the greatest servants of the Lord found in scripture began their journey in youth by learning of the Lord and His ways (1 Kings 18:12; Psalm 71:5; 2 Chronicles 34:3; Job 29:4; Ecclesiastes 12:1). As they approached the prime of life, they invested their learning by serving the Lord (Numbers 8:24-25). As they passed their prime, they would pass their knowledge on to the next generation in hopes of the Lord’s work continuing and flourishing (2 Timothy 4:1-8)..
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.
