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).
Each phase of life bears the marks of certain strengths and weaknesses. In youth, man has a great amount of zeal. In fact, the Bible points out that “the glory of young men is their strength.” A young man might have the fortitude, strength, and stamina to accomplish great things, but his limited knowledge hinders his ability to accomplish greatness. As time elapses, man learns from both failure and success. He obtains the knowledge and enjoys the wisdom that often eluded him during his youth. His glory no longer resides in his strength, but his beauty is now “the gray head.” The very thing that limited his ability to accomplish great things in youth is now a virtue he has achieved. The glory of his youth may have departed, but there remains hope. He has the knowledge but lacks the strength he once possessed. Fortunately, he can invest his knowledge into those who still retain their youthful vitality.
We have already learned that our joy is to be found in the Lord and this joy is a special gift from above. With this truth foundational to our study, what are some things that we can do as believers that will bring us lasting joy? Far too many people think joy surfaces once the stresses of life cease or at least begin to diminish. Yet, the Bible teaches that joy can be found only in faithfully serving the Lord. Today's verse reveals that the disciples found joy through what God had done in and through them! Considering a few more scriptural examples of joy should help to solidify our mindset concerning this subject. The Bible records great joy as the people of God willingly sacrificed to the Lord (1 Chronicles 29:17). Proverbs 21:15 reveals that “It is joy to the just to do judgment.” The book of Luke tells us that there is joy in heaven when one sinner repents (Luke 15:7). From these and other examples, we know that true joy will be found when we willingly serve the Lord God, but never in the things of this world.
