How Do You Live a Life Well? Psalm 90 and God’s Invitation to Wisdom
What does it mean to live a life well?
That question sounds simple, but most of us answer it differently. For some, a life well lived means building financial stability, creating a better future for our children, or leaving behind a legacy. For others, it means helping people, championing justice, growing in character, or making the most of every opportunity we have.
Those are not bad desires. Many of them are good. But Psalm 90 presses us to ask a deeper question: What does God say makes a life well lived?
Psalm 90 gives us an invitation to live our lives well in the light of the Lord. It is a prayer of Moses, the man of God, and it speaks honestly about the shortness of life, the seriousness of sin, the pain of living in a broken world, and the hope of God’s steadfast love.
At the center of the psalm is this prayer: “So teach us to number our days, that we may get a heart of wisdom.”
That is where a life well lived begins. Not with more control, more accomplishments, or more comfort, but with wisdom from God.
God Is Our Dwelling Place
Psalm 90 begins by turning our attention away from our small and fragile lives and toward the eternal God: “Lord, you have been our dwelling place in all generations.”
Before anything existed, God was. Before mountains, nations, cities, homes, careers, families, or our individual lives, God was God. “From everlasting to everlasting, you are God.”
That means the answer to a life well lived cannot be found by starting with ourselves. We are not the center of reality. God is. He is the Creator, the Sustainer, the One who holds all generations in His hands. He is not temporary, fragile, or uncertain. He is the dwelling place of His people.
That image matters. A dwelling place is not simply somewhere you visit in a crisis. It is where you live. It is where you return. It is the place that holds you.
Psalm 90 reminds us that God has always been the refuge of His people. Israel needed to hear this when they returned to a ruined land after exile. Their temple had been destroyed, their city had been broken down, and the place where God’s glory once seemed so visible felt empty. They needed to remember that God had not abandoned them. He was still their dwelling place.
We need the same reminder. We live in a world broken by sin, and we experience that brokenness in our bodies, our relationships, our work, our families, and our hearts. Psalm 90 calls us to fall back into the arms of the faithful Father who knows our pain and gives comfort that only He can provide.
Life Is Shorter Than We Think
Psalm 90 does not flatter us. It tells us the truth about human life. “You return man to dust,” the psalmist says. Human life is compared to a dream, to grass that flourishes in the morning and withers by evening.
That is hard for us to hear because most of us live as though we have unlimited time. We postpone forgiveness. We delay repentance. We assume we will eventually become the kind of people we want to be. We imagine that there will always be more time to seek God, love people, heal relationships, or obey what He has placed before us.
But Psalm 90 tells us that our days are numbered.
This is not meant to make us despair. It is meant to make us wise. When we understand that our lives are brief, we begin to see what matters. We stop treating every inconvenience as ultimate. We stop living as though comfort is the goal. We begin to ask better questions: What is God doing in me? How is He calling me to trust Him? What kind of person am I becoming? How can my numbered days be used for His glory?
That is why the psalmist prays, “Teach us to number our days.”
We cannot learn that wisdom on our own. God must teach it to us.
Sin Has Broken Everything
Psalm 90 is also honest about why life feels so painful. The psalm does not merely say that life is short. It says life is lived under the weight of sin and judgment. “You have set our iniquities before you, our secret sins in the light of your presence.”
That is an uncomfortable sentence. God sees not only the sins others know about, but the hidden ones too. He sees what we have done, what we have desired, what we have avoided, and what we have tried to bury.
The psalm gives voice to the burden of life in a fallen world. It reminds us of what began in Genesis 3, when Adam and Eve sinned and everything started to unravel. Shame entered the human story. Relationships became painful. Work became difficult. Creation itself was cursed. Bodies began moving toward death. Humanity was not destroyed, but our communion with God was bent and broken.
That same disintegration is still at work. Our relationships fracture. Our bodies weaken. Our work frustrates us. Our world groans. Our hearts hide.
Psalm 90 gives us language for that grief. It does not invite us to pretend life is easier than it is. It teaches us to lament honestly before God. Lament is not simply complaining. It is grieving with hope because we know God is good, faithful, and present. God uses lament to shape us, sanctify us, and draw us deeper into His love.
What Do You Do With Your Pain?
Psalm 90 asks a deeply personal question: What do we do with the pain and suffering in our lives?
Some of us avoid it. We hope it will fade if we do not name it. Others try to fix everything immediately. We work harder, take control, change circumstances, or distract ourselves from the ache.
But Psalm 90 invites us to bring our suffering to God. The way forward is not denial or frantic control. The way forward is honest dependence. God wants our attention in suffering, not because He is cruel, but because He is forming us. Pain can become a conduit toward knowing God and His love more deeply.
This does not mean God waves away every hardship. It means He meets us in it. He ministers to us by His Spirit and through His people. He teaches us steadfastness. He builds wisdom. He makes us more like Christ.
Teach Us to Number Our Days
The turning point of Psalm 90 comes in verse 12: “So teach us to number our days, that we may get a heart of wisdom.”
This is not a morbid prayer. It is a hopeful one. The psalmist is asking God to help us live in reality. Our days are limited, our sin is serious, and our suffering is real. But God is eternal, merciful, faithful, and near.
To number our days means we stop pretending we are invincible. It means we stop wasting our lives on what cannot last. It means we ask God to help us live with eternity in view.
A wise life is not necessarily an impressive life. It is not always a comfortable life. A wise life is one lived in God, before God, and for God.
Jesus Answers Psalm 90
Psalm 90 ends with a plea for God to reverse what sin has broken. The psalmist asks God to return, to have pity, to satisfy His people with steadfast love, to make them glad, to show His work to future generations, and to establish the work of their hands.
In other words, the prayer asks God to restore what sin has disintegrated.
The full answer to that prayer is Jesus Christ.
Jesus came as the second Adam. He entered the broken world that Adam’s sin unleashed. He took on flesh, lived faithfully, died in our place, and rose again to begin the restoration of all things. His death paid for sin in full. His resurrection defeated death. Through Him, the curse is being undone.
Psalm 90 has already been answered in Christ, though we do not yet experience that answer in full. We live in the “already, but not yet.” God has already given us His Spirit. He has already offered His steadfast love. He has already begun restoring what sin has broken. But we still wait for the day when every tear is wiped away, every sickness is healed, every sorrow is undone, and everything sad becomes untrue.
That day is guaranteed, not by our work, but by the finished work of Jesus.
Living Well Today
So how do we live a life well today?
We live with our days numbered and our hope secured. We lament honestly. We trust God’s covenant love. We receive the wisdom of the Spirit. We invite other believers into our suffering instead of trying to endure alone. We learn to forgive, to hope, to rest, and to keep walking with God.
A life well lived is not a life without pain. It is a life lived in the Lord, with hope that cannot be taken away.
Psalm 90 invites us to pray: Lord, teach us to number our days. Satisfy us with your steadfast love. Establish the work of our hands. Make us glad in you.
That is the beginning of wisdom.
