Man must spend his strength on things that matter. In doing so, we must focus our efforts upon the right things while working through and by God's power.
The Lord warned His followers about the wickedness of those who have an inordinate desire to be in authority over others. “The princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon them” (Matthew 20:25). The people of God should not be controlled by such men (or women). Those who know and love the Lord should sincerely desire to serve others rather than to be in authority over them. The chief example is the Lord Jesus Christ who “came not to be ministered unto, but to minister, and to give his life a ransom for many” (Matthew 20:28). John gave a similar warning when he spoke of “Diotrephes, who loveth to have the preeminence” (3 John 1:9).
Authority resides upon those who have the right to rule; but, unfortunately, it is not always combined with the ability to rule wisely. In the most basic sense, authority is the right and responsibility to rule others as given to one individual by another. The centurion in Matthew 8:9 expressed this truth when he said that his authority gave him the right to issue commands to his soldiers. The apostle Paul referred to his authority to call for the arrest and persecution of Christians (Acts 9:14; Acts 26:10, 12). This truth was also taught in the parable of the nobleman and his servants where the reward given was authority to rule over cities (Luke 19:17). Unfortunately, this desire for authority over others has been the source of problems and troubles throughout history.
Life is cyclical. Many of the physical challenges experienced by young children will once again be encountered by those who live long enough. As a person ages, many things taken for granted long ago in the prime of life begin to deteriorate. For instance, the Bible says that Israel’s eyes “were dim for age” (Genesis 48:10), Barzillai’s hearing and taste buds were ill affected (2 Samuel 19:34-35), and David “gat no heat” (1 Kings 1:1) as he grew old. For these reasons and others, the Bible emphasizes that aged saints are “old and well stricken in age” (Genesis 18:11). In other words, the passing of time or the coming of age strikes the physical well-being of the body and its physical and mental functions. This physical and mental degeneration is the fulfillment of the cycle of life as the body prepares to return to the dust from whence it originally came (Ecclesiastes 12:7).
