(I recently had the joy of sitting in on a Bible Study led by one of my sons. He was talking about the Psalms, noting that Ps. 89 was the last of Book III, and was the darkest of the sections, as we have seen, written with the backdrop of no Davidic king, apparently in the time of captivity and dispersion. Then he noted how the first Psalm in the next book, Ps. 90, was the only Psalm attributed to Moses. How perfect, he said, that God would remind His people through Moses that however dark the times are, God is still in control, still the One for Israel to trust.)
This Psalm deals with the reality of our lives, that they are comparatively short. And the shortness of life brings with it certain issues and great cause to seek the Lord daily. It is the only Psalm attributed to Moses and is interesting given that the length and strength of his life was exceptional at 120 years (Deut. 34:7).
· 90:1-2: God is eternal. His existence spans all our generations. He existed before creation, meaning He is from everlasting to everlasting because before creation there was no time. He was not far removed from His creation but has been our dwelling place (Heb. ma’own, a place to live in peace, a refuge).
· 90:3-6: On the other hand, man is temporal. Very temporal! God has commanded man to “return” to the dust of the earth from which he was made. The length of our lives is insignificant compared to God’s existence (v4). [Sidebar: this verse does not present an equation that one of our days equals 1000 years of God’s time. Notice it also says 1000 years of God’s time are like a watch in the night. God has no beginning nor end. The point is simply to show how finite and limited we are compared to our Creator.]
· 90:7-11: Additionally we must also say that our lives seem long to us because they are so full of sorrow. That sorrow is our own fault; it is not because of some defect involved in our creation by God. He is angry with mankind because of their sins. The satisfying life in the Garden of Eden was lost when Man sinned. The resulting curse brought labor and sorrow, what verse 3 called destruction, and the result was a life generally of 70 to 80 years.
· 90:12-17: What can we, what should we, do? We should cry out to the One who has been our dwelling place in all generations! Thus Moses does this.
ü Teach us to number our days, v12. What a great prayer. Given our short life there is no time to waste. We must be redeeming the time (Eph. 5:16).
ü Have compassion on Your servants, v13. Given our frailties and God’s righteous anger we should plead for His compassion. Moses uses the same word “return” as in v3: since we are returning to dust He prays God will return to us in compassion rather than turning His face from us. [Sidebar: a literal translation of the last phrase of this verse would be, "repent concerning thy servants." The first use of this word is in Genesis 5:29 where Noah's name is connected with comfort from the work and toil of our hands, in other words the destruction Psalm 90 verse 3 speaks of. Thus, we see that Moses in this Psalm is still seeking that comfort from the effect of sin in our lives and in our world.]
ü Satisfy us early with your mercy, v14. Again, this is so perfect. Our lives are short and deservedly difficult. So we need God’s mercy and, as soon as He is willing, that we might rejoice in Him for more of our lives. [Another sidebar. The word for mercy is the Hebrew chesed, referring to God's General and abundant goodness to us. Mercy finds us in the pit, grace takes us out of the pit, and then God's goodness satisfies the soul.]
ü Make us glad according to our days and years, v15. He prays that God will be our sufficiency every day of every year.
ü Let Your work, Your glory and Your beauty be on us, v16-17a. He desires God to be involved in his life so that he, the man, will be honoring to God. And he prays the same for his own children, that God's glory will be evident to them as well.
ü Only then does he pray: establish the work of our hands, v17b. Our lives will end. We will not have accomplished all that we desired for His glory. We will soon be forgotten. So he asks God to give him a legacy.
Here is a prayer to be prayed frequently by God’s people: for themselves and in intercession for their family members, their friends, their acquaintances.
