The Lord, in His omniscience, has provided man with everything he needs through salvation and the grace that brings salvation. One might ask, “How does salvation teach sobriety?” A proper understanding of grace and salvation reminds man that he is completely inadequate in and of himself. Apart from the Lord’s intervention, man would be on a slippery slope towards the pits of hell. In his very best state, man’s righteous acts are no better than filthy rags (Isaiah 64:6). When a man meditates upon his salvation and the grace of God that gave him salvation, he avoids the snare of pride. He knows full well who he is and what God had to do to make him fit for heaven. He knows he owes the Lord a great debt and determines to be alert in his daily walk.
Most people unfortunately limit the meaning of sobriety to the absence of alcohol, but scripturally speaking, the meaning involves a much broader scope. Sobriety is the opposite of being beside oneself (2 Corinthians 5:13) or mad (Acts 26:25) and is akin to being alert (1 Thessalonians 5:6). The word sober is used in conjunction with the words grave (1 Timothy 3:11; Titus 2:2) and temperate (Titus 1:8; Titus 2:2) indicating that it is accomplished when one is in control, down to earth, and finds the proper balance in his thoughts and actions. One who is sober is humble (Romans 12:3), not drunken (1 Thessalonians 5:7-8), and well aware of the circumstances surrounding him at all times (1 Thessalonians 5:6, 8; 1 Peter 5:8).
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).
