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).
It is easy to tell others what to do and how to do it, but very unwise to fail to follow one’s own instructions and teachings. In fact, man naturally seems to want to place greater burdens upon others than he himself is willing to bear. This was one of the primary issues addressed by those attending the council of Acts chapter 15 in Jerusalem. Peter concluded with the other apostles in agreement that it was not right to ask others to bear a yoke that previous generations were unable to bear (Acts 15:10). This does not mean that believers change their teaching to fit their obedience. Rather, believers ought to obey the truth and teach these truths to others. How many preachers and teachers have spoken about subject matters only to refuse to obey the very truths they have taught to others?
Those with their ear toward the world have many accessible teachers. Unfortunately, far too frequently, that which is being taught contradicts the plain teaching of scripture. In order to combat the propagation of false teaching, the Lord calls upon His people to teach the truth. God placed men within the New Testament church to spread the truth through teaching and preaching (Acts 13:1). He placed older men and women in the church in order to teach the younger men and women (Titus 2:1-8). He placed godly moms and dads in the home to teach the children. Every believer should have a desire to come to a point where he or she can teach others. According to the scriptures, this is the will of God (Hebrews 5:12).
