A wise man is strong and a man of knowledge increases strength. While the world focuses on physical strength, the greater strength is that which is spiritual.
The right kind of sorrow is often needful and brings with it certain benefits. Yet, it is in the joy of the LORD that God's people specifically find strength.
The Lord is the strength of His people. While it is true that we are called to do our part, God must add the necessary strength to accomplish the work.
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).
