Yesterday we meditated on Moses' death. Today we step inside Moses' prayer — Psalm 90, traditionally his own psalm. The man who counted his days teaches us how to pray.
"Lord, you have been our dwelling place in all generations" (v. 1). Prayer starts here: not with my needs, but with God's eternity. Moses spent forty years in the wilderness watching a generation fall — he buried the very people he had led out of Egypt. No one understood transience better. Yet his first word isn't complaint — it's confession: within all that passes away, there is One who is home. Houses collapse. Home does not. Before Moses asks for a single thing, he relocates himself: I may be homeless in the desert, but I am at home in God.
"You turn us back to dust, and say, 'Turn back, you mortals'" (v. 3). "Turn back" also means "repent" — death itself preaches, urging us home. Moses doesn't soften it: "The days of our life are seventy years, or perhaps eighty, if we are strong; even then their span is only toil and trouble; they are soon gone, and we fly away" (v. 10). We fly away — life is not a train; it's a bird.
Then the most famous line: "Teach us to count our days, that we may gain a wise heart" (v. 12). Notice: counting days aims at wisdom, not anxiety. A wise heart knows what can hold weight and what cannot. Yesterday we saw Moses live out the heart of the Law — counting exists so we spend our days on what holds.
Midway through the psalm comes a turn worth lingering over in prayer: "Turn, O LORD! Have compassion on your servants! Satisfy us in the morning with your steadfast love, so that we may rejoice and be glad all our days" (vv. 13–14). "In the morning" — from a man who watched a lifetime of desert sunrises, asking for mercy to arrive as punctually as dawn. The one who counts his days ends up asking not for more days, but to be "satisfied" — fed full — with steadfast love. A person fed full with God's love can rejoice even in brief days. Notice the economy here: joy is not the reward of longevity; it's the fruit of morning mercy.
The psalm ends as a worker's prayer: "Let the favor of the Lord our God be upon us, and prosper for us the work of our hands — O prosper the work of our hands!" (v. 17). "Prosper" — establish — comes twice, like two hands lifting the work up. Moses' hands built a tabernacle, lifted a staff, wrote a law; now he hands those hands over: what I make will pass — make it last, Lord. And notice the order: first "let your favor be upon us," then "prosper the work." Presence before productivity. We usually reverse it — bless my work, then I'll feel Your presence. Moses, at one hundred twenty, finally learned the right order.
This confronts our hurry culture head-on. We count our days to optimize them — calendars, KPIs, five-year plans. Moses counted his to surrender them. The difference is everything: optimization asks, "How much can I fit in?" Surrender asks, "What will You establish?" One ends in exhaustion; the other ends in a prayer that outlives the pray-er by three millennia.
Echoing yesterday's insight: Moses died on Nebo, but his prayer survived him. A person passes; a prayer can live three thousand years. Today, let his prayer become yours.
Looking ahead to the New Testament: what is the destination of counted days? Tomorrow we enter the Gospel and hear Jesus answer in person — everything that holds hangs on two commandments: love God, love your neighbor. The day after, we watch Paul live the answer out.
Prayer guidance: read Psalm 90:1–6, 13–17 three times. First aloud, second silently, third pausing after each verse to answer God in your own words. Linger especially on verses 12 and 17: entrust your "days" and "the work of your hands" concretely — name the work out loud. And try praying verse 14 as your own morning petition for the rest of this week: "Satisfy me in the morning with Your steadfast love, that I may rejoice all my days." Say it before you check your phone. Let mercy set the day's agenda before anxiety does.
Pray with me: Lord, our dwelling place in all generations, our days fly away — teach us to count them. Satisfy us in the morning with Your steadfast love, that we may rejoice all our days. The work of our hands — establish it Yourself. We don't ask for our names to last; only for You to look at the work of our hands and say, "This counts, my child." Amen.
