The brevity of life is a profound theme that underscores the fleeting nature of human existence in comparison to God's eternal perspective. Psalm 90:10 reminds us that the days of our lives are seventy years, or eighty by reason of strength, yet their boast is only labor and sorrow, for life is soon cut off, and we fly away. This sentiment is echoed in Psalm 89:47-48, which earnestly pleads for God to remember how short our time is, highlighting the emptiness, falsity, futility, and frailty of human life, as no man can live and not see death or deliver himself from the powerful hand of sheol, the place of the dead. David, in Psalm 39:5, further emphasizes this transience, declaring that our days are as handbreadths, our age as nothing before God, and every man at his best state is but a vapor. James 4:14 reinforces this by describing life as a wisp of vapor, a puff of smoke that appears for a little while and then disappears into thin air. Moses, in Psalm 90:12, cautions us to number our days that we may gain a heart of wisdom, urging an awareness of life's fleeting nature to align our time with God's will. This perspective contrasts sharply with God's view of time, as Psalm 90:4 states that a thousand years in His sight are like yesterday when it is past, or like a watch in the night, illustrating the vast difference between human frailty and divine eternity. Solomon, in Ecclesiastes 9:11-12, paints a somber picture of life's uncertainty, noting that time and chance happen to all, and man knows not his time of death, likening humans to fish caught in a cruel net or birds in a snare when calamity falls suddenly. This brevity instills a sense of urgency to live purposefully, making the most of each moment, as encouraged by Paul in Ephesians 5:15-16, to walk wisely and redeem the time because the days are evil.
