Psalms 90:17
What does Psalms 90:17 mean?
Let the favor of the Lord our God be on us; establish the work of our hands for us; yes, establish the work of our hands.
The short answer
Psalm 90:17 is the last line of a psalm that spends most of its time facing an uncomfortable truth: human life is short. After meditating on God's eternity and our fleeting years, the psalmist ends with a bold request: "establish the work of our hands." The word appears twice, as if the psalmist is pressing the point. Give our labor permanence. Make what we do last.
That is a striking thing to pray, given everything that came before it. Earlier in the psalm, human life is compared to grass that springs up in the morning and withers by evening, and even a long life of seventy or eighty years passes quickly. If that is true, what could possibly make our work endure? The psalmist's answer is not human effort or achievement, but "the favor of the Lord our God." Only God can give lasting weight to what mortal hands produce.
The verse before this one asks God to show his own work and glorious power to his servants. Read together, verses 16 and 17 suggest that our work becomes durable when it is taken up into God's work. As McCann puts it, when we entrust our lives and future to God, what we do with our hands contributes to something far larger than our own accomplishments—the reign of God itself. Our small projects gain permanence by being folded into God's great one.
There is also a quiet theology of partnership here. McKim points out that God does not accomplish divine purposes by decree alone; God works with and through the people God has made. The prayer of Psalm 90:17 assumes exactly this. It does not ask God to act instead of us, or to bless us while we watch. It asks God to establish work we are actually doing—which means the praying and the laboring belong together.
What scholars say
In the first excerpt, J. Clinton McCann Jr. answers how short-lived people can contribute to something lasting: by entrusting life to God, the work of our hands is joined to God's own work—the reign of God. In the second, Donald K. McKim names the theology behind the prayer, describing cooperation as part of God's providence: God accomplishes divine purposes not by decree alone but by working with and through human beings.
“Yes, the span of even the longest human life is short (v. 10), and yes, human institutions and structures crumble with time, but by looking to God and living for God day by day, we human beings participate in and contribute constructively to something greater than ourselves and our own accomplishments. The phrase “glorious power” in verse 16 translates a Hebrew word associated elsewhere with the proclamation of God’s reign (see “majesty” in Pss. 29:4; 96:6), and the intimation of God’s reign is suggestive. In short, when we entrust life and future to God, “the work of our hands” contributes to God’s “work”—that is, the reign or realm of God.”
“Cooperation (Lat. concursus). A second part of God’s providence is cooperation. The great God cooperates with lesser powers in the universe, which means that the great God cooperates with us as humans. God accomplishes God’s purposes in this world not simply by a divine decree alone. God accomplishes God’s purposes in this world by working along with the human beings God has created. The psalmist prayed, “O prosper the work of our hands!” (Ps. 90:17). God works with us and through us to do God’s will.”
What it means for you
This verse speaks to anyone who has wondered whether their daily work matters. Careers end, projects get replaced, and even good institutions fade. Psalm 90:17 does not deny any of that. Instead, it invites you to pray over your ordinary labor—the parenting, teaching, building, caregiving, creating—and ask God to give it a significance that outlasts you.
It also reframes how we wait on God. If God works through human hands, then prayer and effort are not opposites. You can begin each day asking for God's favor on what you are about to do, and then do it, trusting that faithful work offered to God is never finally lost.
Psalms 90 in context
Psalm 90 is attributed to Moses and opens by calling God a dwelling place for all generations—before the mountains were born, God is God. Against that eternity, the psalm sets human frailty: we return to dust, our years pass like a watch in the night, like grass that withers in a day. The psalmist asks God to teach us to number our days and gain a wise heart. The closing verses turn to petition—for compassion, gladness after affliction, and finally, in verse 17, for God to make our brief work endure.
