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).
Once Judas Iscariot determined to betray the Lord, the earthly ministry of Christ hastened toward the time of His crucifixion. As the time of His death drew near, the Lord Jesus took the disciples to Gethsemane so that He could spend time praying. He asked them to watch while He went to the Father in prayer; however, when the Lord returned from prayer, He found the disciples asleep. He woke them and rebuked Peter saying, “What, could ye not watch with me one hour?” What a horrible rebuke as Peter, along with the others, realized that he had failed this one simple request! After everything that the Lord had done for the disciples, they could not force themselves to watch for one hour. In like manner, many believers are going to find out the consequences at the judgment seat of Christ of failing to watch for the Lord.
