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)..
Sometimes the most difficult and significant tasks involve the simplest truths. For instance, every Christian should quickly learn that vengeance belongs unto the Lord. God confirms as much throughout scripture (Deuteronomy 32:35; Psalm 94:1; Romans 12:19; Hebrews 10:30). This should be understandable as only the Lord has all the necessary information to execute just vengeance 100 percent of the time. When man attempts to execute vengeance, he often does so out of an improper motive or without key information of the evil that appears to have been done. Furthermore, when a believer takes vengeance into his own hands, he robs the Lord of His right and responsibility to exact vengeance at the right time and in the right manner.
