God tasks the watchman with some tremendous responsibilities. He has to remain alert for troubles at all hours of his watch and cannot slacken his resolve to stay attentive. Yet, we are told that if the Lord chooses not to intervene, all of the watchman’s worries and efforts are simply in vain. Interestingly, the watchman’s job is to worry! The fear of trouble keeps him up at night and causes him to rise up early in the morning to do his duty. Eventually, however, this worry produces physical ailments within the individual. With these negative outcomes, the worry and anxiety also provide no solution for the problems of this life. Worrying has deprived many good people of restfulness and sleep without offering the desperately sought after solutions. It is important to note that help has never come simply as a result of one’s worry, and no problems ever resolved themselves simply due to the magnitude of one’s worry. Bottom line: except the Lord intervenes in the problems at hand, no help will be forthcoming. Worry is vain!
Believers are commanded to “Be careful for nothing.” Contextually, the word careful means to be care full or full of cares. That being said, this is one of the most disobeyed commands in all of scripture. In Matthew 6:25, the Lord warned His disciples against dwelling upon or worrying about what they would eat, or drink, or how they would be clothed. The Lord’s rebuke implies that not even the necessities of life should serve as a source of worry for God’s people. It is important to note that worry and faith are at opposite ends of the spectrum because they do not and cannot coexist within the believer’s life and walk. A believer who is “careful” for things cannot and will not simultaneously trust God’s faithful provision. When a believer worries rather than trusting in God’s provision and protection, the believer’s actions deem God incapable to accomplish the matter without the individual contributing his “carefulness.”
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).
