Some psalms are on everyone’s list of favorites. They contain poignant phrases and urgent cries that resonate deeply with our own hearts.
Sometimes we love these psalms—or portions of these psalms—without looking at them carefully. Today we’ll take a close look at Psalm 90.
Our Sovereign God is Everlasting
This is the only Psalm attributed to Moses, and he wrote the whole psalm as a corporate prayer addressed directly to God.
The theme of time is inescapable in Psalm 90, showing up in nearly every verse. To avoid cluttering this article with these observational details, I’ve put that list in this document here.
God has been his people’s “dwelling place in all generations” (Ps 90:1). This is personal. He is God and has been God even before he created the world (Ps 90:2). So while God is certainly the creator, he is more than the creator.
God created man from dust and calls him back at the end of life. This God is in control of the span of human days (Ps 90:3).
Time does not function for God the way it does for us. A thousand years for God is like a day (Ps 90:4). He sweeps millennia away like a dream (Ps 90:5); they rise and fall as quickly as the morning and evening (Ps 90:6).
Our Short Life, in View of God’s Wrath
The middle of Psalm 90 is unsettling, because Moses makes frequent mention of God’s wrath. God’s “anger” or “wrath” appears five times in Psalm 90:7–11.
God’s anger troubles his people (Ps 90:7). But the reason for God’s wrath is not mysterious.
You have set our iniquities before you,
our secret sins in the light of your presence. (Psalm 90:8)
Because our sins are obvious to God, “our days pass away under [his] wrath” (Ps 90:9). Though we may live to be seventy or eighty, our years are “toil and trouble,” and “they are soon gone” (Ps 90:10). With God’s perspective on time, our lives are a blink on the horizon.
Moses brings us around the corner of somberness in verse 11. Many consider God’s wrath, but who does so according to the fear of the Lord? (See Ps 90:11). This posture, and not one of mere terror before God, leads to a proper, sober application of the truth of a brief life. “So teach us to number our days, that we may get a heart of wisdom” (Ps 90:12). Notably, this is Moses’s first request in this prayer.
God’s Favor Makes All the Difference
While verses 7–12 show us the brevity of life in view of God’s wrath, verses 13–17 point to the mercy of God.
Moses longs for God’s nearness, for the mercy of his return (Ps 90:13). The psalm then explains what such a return would mean for God’s people.
God is not only angry at sin, he is known for his steadfast love. This steadfast love, once shown to his people, would sustain them with joy all of their days (Ps 90:14). Though there has been affliction and evil—think of all Moses and the Israelites experienced in Egypt!—God is able to bring them unending gladness (Ps 90:15).
With this as the backdrop—God’s return, bringing his satisfying, steadfast love to his people—Moses turns to pray about the Israelites’ work in the world. He asks God to show his work and his “glorious power” to his servants and their children (Ps 90:16). Then, in light of God’s work, and if his favor is upon them, can his people pray about their own work in the world: “Establish the work of our hands upon us; yes, establish the work of our hands!” (Ps 90:17)
Application From a Favorite Psalm
In this psalm, God’s people praise God for his sovereign, eternal nature and they consider their own time-bound lives. They consider God’s anger toward sin and his steadfast love. So, what is Moses’s main point in writing this psalm?
In our brief lives, we must seek our satisfaction in the steadfast love of the everlasting God.
What are some possible applications? As we consider our brief time on earth, we should number our days. This means we should celebrate birthdays with both joy and sobriety. We should hold our years loosely. At the start of each day we should commit our upcoming hours to the Lord, and we should return thanks to him as each day comes to a close.
If that was an inward application, here’s an outward one. We can help our friends consider their work in light of the Lord’s work. In our churches, we can regularly celebrate God’s work in our communities, we can pray for his ongoing favor, and we can ask him to establish the work of our hands.
