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)..
From youth, man is gripped by sin’s attraction. As he ages, the source of temptation may vary, but the fact that he is tempted remains constant. Paul instructed young Timothy to “flee . . . youthful lusts” (2 Timothy 2:22), yet Solomon’s heart was turned after other gods when he “was old” (1 Kings 11:4). Many believers have wasted the precious years of youth by succumbing to the youthful lusts of which Paul warned Timothy. Others have fought the good fight in their youth, only to regretfully compromise in their waning years. There is no time or age for the believer to be at ease concerning sin. Sin can be pleasurable but is always deceptive with uncertain outcomes for those who indulge.
Each phase of life bears the marks of certain strengths and weaknesses. In youth, man has a great amount of zeal. In fact, the Bible points out that “the glory of young men is their strength.” A young man might have the fortitude, strength, and stamina to accomplish great things, but his limited knowledge hinders his ability to accomplish greatness. As time elapses, man learns from both failure and success. He obtains the knowledge and enjoys the wisdom that often eluded him during his youth. His glory no longer resides in his strength, but his beauty is now “the gray head.” The very thing that limited his ability to accomplish great things in youth is now a virtue he has achieved. The glory of his youth may have departed, but there remains hope. He has the knowledge but lacks the strength he once possessed. Fortunately, he can invest his knowledge into those who still retain their youthful vitality.
