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)..
Unfortunately, some Christians have become convinced that old age serves as a sufficient excuse for a lack of service to the Lord’s work. Granted, the field of one’s service may change, but there should always remain a willingness to serve. For instance, Moses received his initial call to deliver Israel at forty years old (Acts 7:23) but did not lead God’s people out of Egypt until he was eighty (Exodus 7:7). When he died at 120 years of age, he remarked that “his eye was not dim, nor his natural force abated” (Deuteronomy 34:7). At forty years of age, Caleb received a promise from Moses concerning the possession of land in Canaan (Joshua 14:7-9). Forty-five years later, Caleb took possession by driving out the mighty Anakims (Joshua 14:10-12). Caleb did something in his old age that many of the young men could not or would not attempt (Joshua 17:13).
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.
The strength of any people will be determined by how they deal with two people groups: their young and their old. If at any point, either of these two groups becomes viewed as simply burdensome, both will cease to effectively attain God’s intended desire for society. The aged members of society are most often its wisest. They have had successes and failures and learned from both (Deuteronomy 32:7). They have witnessed the Lord’s provision through difficult times (Psalm 37:25). God purposed for the aged to instruct the young in practical and spiritual matters (Titus 2:1-11). While the young should feed off of the wisdom of the aged, the elderly members of society can be nourished by the joy, strength, and life of younger people (Ruth 4:15).
Life is cyclical. Many of the physical challenges experienced by young children will once again be encountered by those who live long enough. As a person ages, many things taken for granted long ago in the prime of life begin to deteriorate. For instance, the Bible says that Israel’s eyes “were dim for age” (Genesis 48:10), Barzillai’s hearing and taste buds were ill affected (2 Samuel 19:34-35), and David “gat no heat” (1 Kings 1:1) as he grew old. For these reasons and others, the Bible emphasizes that aged saints are “old and well stricken in age” (Genesis 18:11). In other words, the passing of time or the coming of age strikes the physical well-being of the body and its physical and mental functions. This physical and mental degeneration is the fulfillment of the cycle of life as the body prepares to return to the dust from whence it originally came (Ecclesiastes 12:7).
