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).
The Lord healed many people during His earthly ministry. Today's passage speaks of a particular man who had been delivered from devil possession. What a relief he must have experienced! However, the people in his community did not rejoice that the Lord had performed such a wonderful miracle. In fact, they turned against the Saviour and wanted Him to depart from their coasts. The Lord complied with their demands; however, the man delivered of the devils wanted to travel with the Lord. He loved the Lord so much that he wanted to stay close to Him. However, as the healed man sought to enter the ship, Christ told him to return to his home and tell his friends what had happened to him. The Lord knew that this man was in the best position to reach out to his friends with the truth. He knew this man's testimony concerning the truth was what they needed to hear and believe. Christians should always be prepared and ready for times when opportunities arise to tell their friends about the truth. Acts chapter 10 records another example when Cornelius called his friends together expecting to hear Simon Peter preach the truth of the gospel. Real friends insure that their friends are put into a position to hear the truth and never squander spiritual opportunities.
