Historical & Cultural Context

A Prayer from the Wilderness

This psalm is uniquely attributed to Moses, placing its setting in the wilderness during Israel's forty years of wandering. This was a generation under God's judgment, facing the reality of their own mortality as they were barred from the Promised Land. This backdrop of discipline and transience gives the psalm its raw honesty about life's hardships and the consequences of sin. It is a community lament, spoken on behalf of a people keenly aware of their fleeting existence.

From Sober Reality to Hopeful Plea

The psalm follows a powerful emotional and theological arc, moving from sober reflection to hopeful petition. It begins by magnifying God's eternal nature against the backdrop of human frailty. It then honestly confronts the reason for this hardship - God's wrath against sin - before pivoting to a heartfelt plea for wisdom, mercy, and joy. The prayer doesn't end in despair but with a forward-looking request for God's favor to give their lives meaning, modeling a journey from lament to hope.

A Verse-by-Verse Journey Through Psalm 90

Psalm 90, the great prayer of Moses, unfolds as a conversation with the eternal God from the perspective of mortal man. It begins by establishing God's timeless majesty before turning to the harsh realities of a short and difficult life. The psalm then pivots, making a desperate and beautiful plea for the wisdom to live meaningfully and for God's favor to rest upon His people, giving their work lasting significance.

God's Eternity and Our Frailty  (Psalm 90:1-6)

1 Lord, you have been our dwelling place in all generations.
2 Before the mountains were brought forth, or ever you had formed the earth and the world, from everlasting to everlasting you are God.
3 You return man to dust and say, “Return, O children of man!”
4 For a thousand years in your sight are but as yesterday when it is past, or as a watch in the night.
5 You sweep them away as with a flood; they are like a dream, like grass that is renewed in the morning:
6 in the morning it flourishes and is renewed; in the evening it fades and withers.

Commentary:

God is our eternal home, while our lives are as brief and fragile as grass that withers in a day.

Moses begins by establishing God as the eternal 'dwelling place' - the only true source of security for His people through all time. This infinite God, who existed before the mountains were formed, is contrasted with humanity. Our lives are compared to grass that flourishes in the morning but is cut down and withered by evening. A thousand years, a vast span for us, is like a single day or a few hours of the night to God. This powerful imagery isn't meant to devalue us, but to give us a proper perspective on our place in the universe. We are temporary, but our home is in the One who is eternal.

The Weight of Sin and God's Wrath  (Psalm 90:7-11)

7 For we are brought to an end by your anger; by your wrath we are dismayed.
8 You have set our iniquities before you, our secret sins in the light of your presence.
9 For all our days pass away under your wrath; we bring our years to an end like a sigh.
10 The years of our life are seventy, or even by reason of strength eighty; yet their span is but toil and trouble; they are soon gone, and we fly away.
11 Who considers the power of your anger, and your wrath according to the fear of you?

Commentary:

Our short and troubled lives are a consequence of our sin, which stands exposed before a holy God.

The psalm takes a sobering turn, explaining why life is so fleeting and full of trouble: God's righteous anger against sin. Moses is brutally honest, acknowledging that their suffering is a direct consequence of their rebellion. He states, 'You have set our iniquities before you, our secret sins in the light of your presence.' This is the just response of a holy God to wrongdoing. It is not the anger of a petty tyrant. The psalmist recognizes that their days pass under this cloud of wrath, ending 'like a sigh.' This section is a crucial admission of responsibility, understanding that their hardship is rooted in their broken relationship with God.

A Prayer for Wisdom and Renewed Joy  (Psalm 90:12-15)

12 So teach us to number our days that we may get a heart of wisdom.
13 Return, O Lord! How long? Have pity on your servants!
Satisfy us in the morning with your steadfast love, that we may rejoice and be glad all our days.
15 Make us glad for as many days as you have afflicted us, and for as many years as we have seen evil.

Commentary:

Recognizing life's brevity, the psalmist prays for wisdom to live meaningfully and for God's love to restore their joy.

This is the heart of the psalm, where lament turns into petition. Having accepted reality, Moses makes an important request: 'So teach us to number our days that we may get a heart of wisdom.' He doesn't ask for more days, but for the wisdom to make each day count. This is followed by a cry for God's mercy and presence - 'Return, O Lord! How long?' He asks God to satisfy them in the morning with His 'steadfast love' so they can experience joy again. The request to 'make us glad for as many days as you have afflicted us' is a bold prayer for restoration, asking for joy to match their years of sorrow.

A Hope for Lasting Purpose  (Psalm 90:16-17)

17 Let the favor of the Lord our God be upon us, and establish the work of our hands upon us; yes, establish the work of our hands!
17 Let the favor of the Lord our God be upon us, and establish the work of our hands upon us; yes, establish the work of our hands!

Commentary:

The psalm ends with a hopeful plea for God's favor to give their work and lives lasting meaning.

The prayer concludes with a look toward the future, asking for God's favor to give their lives meaning. Moses prays, 'Let the favor of the Lord our God be upon us, and establish the work of our hands.' After reflecting on how quickly life fades, this is a plea for their efforts to have lasting significance. It's a recognition that without God's blessing, everything they do is ultimately temporary and meaningless. This final request places all their hope for purpose and legacy in the hands of the gracious, eternal God.

God's Timelessness and Our Brief Lives

The Eternality of God

Psalm 90 powerfully declares that God is 'from everlasting to everlasting.' He exists outside of time and is the uncreated Creator, making Him the only stable and secure 'dwelling place' in a universe where everything else is temporary.

The Brevity of Human Life

The psalm uses vivid metaphors like dust, a flood, a dream, and withering grass to emphasize how short and fragile our lives are. This realism is not meant to cause despair, but to create an urgency to live for what truly matters.

Wisdom as Right Perspective

The central request to 'number our days' is a prayer for perspective. Biblical wisdom involves seeing life from God's point of view - recognizing our limits and living with purpose in the time we have.

Dependence on God's Favor

The psalm concludes that human effort is ultimately futile without God's blessing. The prayer to 'establish the work of our hands' reveals that true and lasting meaning is found only when our lives are aligned with God's will and empowered by His grace.

True wisdom lies in acknowledging the fleeting nature of our days and aligning our lives with eternal truths.

Living Wisely in Light of Eternity

How does recognizing life's brevity change my daily priorities?

Psalm 90:12 urges you to 'number your days' to gain wisdom. This means consciously shifting your focus from temporary anxieties and fleeting pleasures to things of eternal value, like your relationship with God and others. It challenges you to live each day with intention, treating your time as a precious gift.

Where do I find my security and 'dwelling place'?

Moses declares, 'Lord, you have been our dwelling place in all generations' (Psalm 90:1). This psalm invites you to find your ultimate security not in your career, finances, or even family, but in the unchanging character of God. He is the only permanent home in a world where everything else eventually fades away.

How can I find joy and purpose even in difficult seasons?

The prayer to be satisfied with God's love in the morning (Psalm 90:14) teaches that joy is not based on perfect circumstances but on God's presence. Even when facing hardship, you can ask God to fill you with His steadfast love, which brings a deep and resilient gladness that circumstances cannot take away.

Finding Purpose in Fleeting Time

Psalm 90 delivers an important and timeless message: our lives are incredibly short, but they can be filled with eternal meaning. By contrasting our fleeting days with God's everlasting nature, Moses reveals that wisdom isn't about living longer, but about living for what lasts. The psalm is a call to exchange anxiety over our limitations for a humble dependence on God, asking Him to give our work purpose and our days joy.

What This Means for Us Today

The prayer of Psalm 90 is an invitation to gain a divine perspective. It asks us to pause, look up from our brief and busy lives, and see the eternal God who is our true home. This shift invites us to live not in fear of our mortality, but in the wisdom and joy that comes from seeking God's favor each and every day.

  • What 'secret sins' (v. 8) might be hindering my relationship with God and my ability to live wisely?
  • How can I start my day asking God to 'satisfy' me with His love (v. 14)?
  • In what specific area of my life do I need to pray, 'establish the work of my hands' (v. 17)?
Acknowledging our fleeting existence leads to a deeper appreciation for the eternal.
