Perhaps only Isaiah 40 can compare with this psalm in presenting God's grandeur and eternity in contrast to our frailty and mortality. Moses' point, however, is that God's eternity is the answer to our problem with time.
One might think that we hardly need to be reminded of this. But when the misconception that we are already immortal ("You shall not surely die") is combined with our innate and powerful proclivity toward abusing time, it is urgently necessary that God emphasize this on occasion.
God often underscores the brevity of our lives. Job laments: "Now my days are swifter than a runner; they flee away, they see no good. They pass by like swift ships, like an eagle swooping on its prey" (Job 9:25-26). In Psalm 39:4-5, David prays:
LORD, make me to know my end, and what is the measure of my days, that I may know how frail I am. Indeed, you have made my days as handbreadths, and my age is as nothing before You; certainly every man at his best state is but vapor. Selah.
And finally Asaph writes, "For He remembered that they were but flesh, a breath that passes away and does not come again" (Psalm 78:39).
The rapid passage of time is something we need to be serious about. We cannot live as though there is no day of reckoning because judgment is now upon the household of God (I Peter 4:17).

Simplify Your Life!
Psalm 90 gives us probably the best biblical perspective of time. This psalm, the only one attributed to Moses, compares how man and God view time and life. His conclusion, of course, is that man and God look at time from entirely different perspectives. It is this difference in point of view that makes a huge difference in how we conduct our lives.
Moses begins by asserting that God is everlasting and almighty (verses 1-2). He can destroy men's lives, and a thousand years later, He resurrects them to life with a word (verses 3-4)! Thousands of years can pass, and God can still bring people back from the dead! Man has no power over death, but God can, has, and will overcome time and death by the power of the resurrection. To God, these thousands of years pass swiftly "like yesterday . . . like a watch in the night."
This is far different from man's point of view. "The days of our lives are seventy years; and if by reason of strength they are eighty years, yet their boast is only labor and sorrow; for it is soon cut off, and we fly away" (verse 10). Ethan, the psalmist of Psalm 89:47-48, echoes this in his plea to God:
Remember how short my time is; for what futility have You created all the children of men? What man can live and not see death? Can he deliver his life from the power of the grave? Selah.
