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).
In Bible times, cities would often build towers to watch the gates to avoid dangers looming from without (Isaiah 21:8). Watchmen would take turns watching the gate. These watchmen were responsible for sounding a trumpet should any danger appear (Ezekiel 33:6). The apostle Paul in his writings applied a spiritual application to this literal act of being a watchman. Just as cities needed men willingly staying awake and alert while others slept or were busy in their daily routines, churches need believers sober and watchful while others might be cumbered about with the cares of this world. Today’s watchmen must use their voices like a trumpet to sound the alarm when danger nears.
