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).
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).
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.
Many people suffer from gerascophobia which is the fear of growing old. Perhaps this condition is ultimately the fear of death rather than simply growing old, but other conditions indicative of old age cause people to fret. One of these concerns was expressed by the penman of Psalm 71. On two separate occasions, he requested that the Lord would not forsake him when he was old and grayheaded (Psalm 71:9, 18). The Lord knew the fears of man and promised, “even to your old age . . . and even to the hoar hairs will I carry you: I have made, and I will bear; even I will carry, and will deliver you” (Isaiah 46:4). The thought of growing old should not bring fear or trepidation to God’s people. In fact, the Bible points to it as a blessing and one of the greatest blessings the Jewish people will experience in the kingdom (Zechariah 8:4).
