Psalm 39 O Lord Help Me to Know My End
Title: “O Lord, Make Me Know My End”
Text: Psalm 39:1–13
Setting: Sunday Evening Worship
Introduction
Beloved congregation of the Lord Jesus Christ,
There are certain subjects that we, as human beings, would rather avoid. We fill our days with activity, our ears with noise, and our schedules with tasks—partly, perhaps, to drown out the deeper questions that haunt us: How long do I have to live? What will become of me when I die? What is the point of all my striving if I must soon leave it all behind?
Psalm 39 forces us to face those questions head-on. It is one of David’s most searching and sobering prayers. You will notice it is not a psalm of praise or thanksgiving. It is a psalm of lament, born out of deep affliction. David is wrestling with the brevity of life, with the futility of human labor, and with the heavy hand of God’s discipline. He cries out: “O LORD, make me know my end and what is the measure of my days; let me know how fleeting I am!” (v. 4).
In this psalm, David comes to terms with truths that every one of us must reckon with sooner or later:
- Life is short.
- Death is certain.
- Wealth and human achievements cannot last.
- And only God Himself can be our hope.
This is not morbid reflection. It is wisdom. Moses prayed in Psalm 90:12, “So teach us to number our days that we may get a heart of wisdom.” In the same spirit, David here is asking the Lord to make him deeply aware of the brevity of life, so that he might live wisely, humbly, and hopefully before God.
Psalm 39 is unique in that it leaves us with a sense of longing rather than resolution. It ends with a plea, not a triumph. But that longing is meant to drive us beyond David to David’s greater Son—the Lord Jesus Christ—who entered into our frailty, bore our rebuke, and secured for us eternal hope.
So tonight, as we study this psalm, I want us to walk with David through his struggle: his silence, his lament, his confession, and his prayer. And in each movement, we will see how Christ fulfills this psalm and how He enables us to live as pilgrims in this fleeting world.
Sermon Theme: Because life is fleeting and uncertain, we must fix our hope in the Lord through Christ, who alone gives permanence and peace.
We will consider the psalm in four parts:
- A Resolution to Guard the Tongue (vv. 1–3)
- The Brevity and Vanity of Life (vv. 4–6)
- Turning to God in Hope (vv. 7–11)
- The Plea of a Pilgrim (vv. 12–13)
I. A Resolution to Guard the Tongue (vv. 1–3)
David begins his psalm not with his affliction but with his resolution: “I said, ‘I will guard my ways, that I may not sin with my tongue; I will guard my mouth with a muzzle, so long as the wicked are in my presence.’” (v. 1).
David knows that suffering has a way of loosening the tongue. Pain presses us to speak quickly, often foolishly. When pressed by trial, how easy it is to murmur against God, or to lash out at others. David, however, is determined not to dishonor the Lord. He will not give the enemies of God occasion to scoff. In the ancient world of honor and shame, the careless word of Israel’s king would bring not only personal shame but dishonor upon the Lord whom he served.
So David restrains himself. He resolves to place a muzzle on his mouth—like one placed on an animal—lest in the heat of trial he say what cannot be unsaid. Verse 2 says, “I was mute and silent; I held my peace to no avail, and my distress grew worse.” His silence was costly. His grief churned within, and his sorrow deepened. By verse 3, he confesses, “My heart became hot within me. As I mused, the fire burned; then I spoke with my tongue.”
What a vivid description of the human heart! We bite our tongues, but grief grows hotter and hotter until it bursts forth. But notice carefully: David’s words do not break out in anger toward men, nor in complaint before his enemies. He takes his anguish to God. His tongue, though burning, pours itself out in prayer. That is wisdom.
The lesson for us is clear: when suffering comes, when grief weighs upon us, the right response is not to vent before the watching world. It is not to take our complaint to social media, or to lash out at those around us, or to speak rashly and sin against the Lord. No—the right place to take our words is into the presence of God in prayer.
But dear friends, here is the challenge: who among us has perfectly guarded the tongue? How often have you spoken words in anger, words of complaint, words of gossip, words of despair? How many times have you regretted what you said—yet could not take it back? David’s resolution is noble, but it exposes our weakness.
This is where the psalm drives us to Christ. Peter tells us of our Lord Jesus: “When he was reviled, he did not revile in return; when he suffered, he did not threaten, but continued entrusting himself to him who judges justly.” (1 Pet. 2:23). Here is the true King who fulfilled what David longed to do. Christ guarded His tongue under far greater provocation. False witnesses accused Him. Soldiers mocked Him. Crowds hurled insults at Him as He hung upon the cross. Yet not a rash or sinful word escaped His lips. Instead, He prayed, “Father, forgive them, for they know not what they do.”
Jesus not only gives us the perfect example of a bridled tongue—He is the Redeemer for our unbridled ones. Every idle word that you and I have spoken was laid upon Him at the cross. He bore the guilt of our rash speech, our gossip, our complaints, our slanders. And now, risen from the grave, He pours out His Spirit upon His people to tame our tongues and to sanctify our speech.
Beloved, what does this mean for us? It means that in Christ you are forgiven for every careless word. And it means that by His Spirit you can grow in wisdom, so that your lips become instruments of blessing rather than destruction.
Searching Applications:
- To the careless: Do you let your tongue run unchecked? Do you gossip, complain, or lash out in anger? Repent, and look to Christ who died for your words. Pray that His Spirit would set a guard over your lips.
- To the weary: Do you carry sorrows in silence until they fester? Do not let your heart burn in bitterness. Follow David’s path: pour out your complaint not before men but before God. Christ, your sympathetic High Priest, invites you to come to Him with your groaning.
- To the young: Do not excuse cruel words as “just joking.” Jesus said we will give account for every careless word (Matt. 12:36). Seek His grace now to shape your speech.
David resolved to guard his tongue. He struggled under the weight of silence. And at last, his words burst forth—not against men, but upward to God in prayer. And in Christ, that resolution is fulfilled perfectly and shared with us. He is the Word made flesh, whose words were always true and pure, and who gives His people lips of praise instead of rash complaint.
Transition: From his silence, David’s burning heart erupts in prayer. But what does he pray? Not for revenge upon his enemies. Not for ease from his pain. His first request is far deeper: that the Lord would teach him the brevity of his days.
II. The Brevity and Vanity of Life (vv. 4–6)
David’s tongue has finally been loosed, but what does he pray? Not first for deliverance from enemies, nor even relief from suffering. His first request is deeper, more searching:
“O LORD, make me know my end and what is the measure of my days; let me know how fleeting I am!” (v. 4).
This is the heart of wisdom—to ask God to impress upon us the shortness of life. David does not simply acknowledge this truth intellectually; he prays that it would sink into his heart. For we can easily say, “Yes, life is short,” and then live as though it will last forever. David prays for the grace to live in the light of eternity.
He continues in verse 5: “Behold, you have made my days a few handbreadths, and my lifetime is as nothing before you.” A handbreadth was the smallest measure in Hebrew reckoning—only about three inches wide. David is saying: “Lord, my life is not even the span of a cubit; it is the smallest measure in Your sight.” Then he adds: “Surely all mankind stands as a mere breath!” That word breath is the same Hebrew word (hebel) used in Ecclesiastes—vanity, vapor, mist.
Verse 6 presses the point further: “Surely a man goes about as a shadow! Surely for nothing they are in turmoil; man heaps up wealth and does not know who will gather!” What a piercing picture: men rushing, striving, sweating to accumulate wealth, and then death comes—and another man reaps the fruit. A lifetime of labor vanishes in a moment, leaving nothing behind but a shadow.
Historical and Rhetorical Background
In the ancient world, wealth, land, and inheritance were everything. To secure property for your descendants was the chief mark of success. Yet here David acknowledges the futility of it all. In the end, he says, we are shadows; the things we pile up will be left behind for others.
Notice also the rhetorical force of this stanza: the repeated word “surely” (’ak) in verses 5 and 6—surely, surely, surely! The repetition hammers the truth into our hearts. There is no escaping it: life is short, man is vain, death is certain.
Biblical-Theological Trajectory
This theme runs like a thread through Scripture:
- Job 14:1–2: “Man who is born of a woman is few of days and full of trouble. He comes out like a flower and withers; he flees like a shadow and continues not.”
- Isaiah 40:6–8: “All flesh is grass… the grass withers, the flower fades, but the word of our God will stand forever.”
- James 4:14: “What is your life? For you are a mist that appears for a little time and then vanishes.”
David here is in harmony with the whole Bible: life is fragile, fleeting, and frail.
Christ’s Fulfillment
But here is where the psalm presses us to Christ. The eternal Son of God entered this brevity. He did not come to earth as an immortal conqueror immune to our frailty. He took on our flesh and lived our fleeting life. His days, too, were like a handbreadth—barely thirty-three years. Isaiah said, “He was cut off out of the land of the living” (Isa. 53:8). He knew the transience of human existence, but He lived it without vanity.
While men heap up wealth they cannot keep, Jesus laid up no treasure for Himself. He had no house to leave, no fortune to pass on, no monument to preserve His memory. Instead, He gave His life to secure for us what we could never achieve: “an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you” (1 Pet. 1:4). He entered our brevity to give us eternity. He embraced our frailty to give us strength. He endured our mortality to grant us everlasting life.
Searching Applications
- To the proud and self-sufficient: Do you think you have endless days to make your mark? Remember David’s prayer: your life is a breath, a shadow. Humble yourself before the Lord, for your time is short.
- To the prosperous: Are you laboring to heap up wealth, to secure legacies, to build reputations? Friend, you cannot take it with you. Death will strip it away, and another will gather. Seek instead the treasures that moth and rust cannot destroy, the riches Christ alone provides.
- To the young: Do not think these words are only for the elderly. The graveyards are filled with both the old and the young. Your life, too, is a vapor. Do not put off Christ until later. He calls you now, in the days of your youth, to remember your Creator (Eccl. 12:1).
- To all God’s people: Let the brevity of life make you wise. Moses prayed, “Teach us to number our days that we may get a heart of wisdom” (Ps. 90:12). Live each day as a gift, each breath as grace, each moment as preparation for eternity.
Transition
David has looked honestly at life’s shortness and man’s vanity. He has acknowledged that riches cannot last and labor cannot save. Where, then, is hope? His prayer takes a turn in verse 7: “And now, O Lord, for what do I wait? My hope is in you.”
III. Turning to God in Hope (vv. 7–11)
David has considered the shortness of life and the vanity of human striving. He has seen that man is a breath, a shadow, a vapor. But he does not end in despair. Verse 7 marks the turning point of the psalm:
“And now, O Lord, for what do I wait? My hope is in you.”
Here the tone shifts from lament to faith. The word now is crucial. In light of the futility of wealth and the fleeting nature of life, now—in this moment of clarity—David resolves to place all his expectation in the Lord. This is the only sane conclusion. If life is short and death is certain, if riches cannot last and toil cannot save, then there is only one place to look: the Lord Himself.
Exposition of the Passage
David immediately couples this hope with confession: “Deliver me from all my transgressions. Do not make me the scorn of the fool!” (v. 8). The problem is not only life’s brevity—it is our sin. What makes death fearful is not just that it ends our earthly pursuits but that it ushers us before the judgment seat of God. So David pleads for forgiveness.
In verses 9–11, he acknowledges that his suffering is not random but the hand of God:
- “I am mute; I do not open my mouth, for it is you who have done it” (v. 9).
- “Remove your stroke from me; I am spent by the hostility of your hand” (v. 10).
- “When you discipline a man with rebukes for sin, you consume like a moth what is dear to him” (v. 11).
David interprets his affliction as divine discipline. Just as a moth silently destroys a garment, so God strips away earthly security until man is left with nothing but God Himself.
Socio-Historical and Rhetorical Insight
In the worldview of Israel, affliction was always to be interpreted theologically. It was never mere chance. Suffering was either God’s chastisement for sin, or His fatherly training for holiness. The repetition of “surely” continues in verse 11—“surely all mankind is a mere breath”—underscoring the certainty of God’s judgment and our frailty under His hand.
Christ’s Fulfillment
Here we must see the gospel shining through. David felt the heavy hand of God’s discipline, but only in part. Christ bore it in full. Isaiah prophesied: “He was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed” (Isa. 53:5).
At the cross, Jesus bore not only fatherly discipline but divine wrath. He endured the hostility of God’s hand—not for His sin, but for ours. The consuming moth of judgment fell upon Him, so that those who trust in Him might be clothed with garments that never fade.
And because Christ bore wrath in our place, our afflictions now have a new meaning. They are no longer punitive. They are not condemnations. They are fatherly disciplines, designed to wean us from idols and train us for holiness. Hebrews 12:10 says, “He disciplines us for our good, that we may share his holiness.”
Thus Psalm 39 drives us to Christ: He is the one in whom forgiveness is found, the one who bore our rebuke, the one who transforms our trials into instruments of grace.
Searching Applications
- To the afflicted: When God’s hand is heavy upon you—through sickness, loss, disappointment—do not think it is His wrath. Christ has borne wrath for you. See instead a Father’s discipline, meant to draw you nearer to Him.
- To the weary: Do you feel consumed, as if moths have eaten away what you love? Take comfort: God strips us of lesser things so that He might give us Himself. Hope in Him.
- To the unrepentant: If you remain outside of Christ, your suffering is only the foretaste of judgment. Flee to Christ, who bore the chastisement that you deserve.
- To the proud: Have you grown bitter under trial, accusing God or resenting His providence? Learn from David’s silence: “I am mute; I do not open my mouth, for it is you who have done it.” Submit yourself under His mighty hand.
- To the church: Let us encourage one another in suffering. We walk together under the Father’s discipline, and together we point one another to the hope that is in Christ.
Transition
David has turned from despair to hope, from complaint to confession, from lament to submission. Yet the psalm is not finished. He closes not with triumph but with a pilgrim’s plea—a reminder that this world is not our home.
IV. The Plea of a Pilgrim (vv. 12–13)
David closes his psalm with a deeply personal and emotional prayer:
“Hear my prayer, O LORD, and give ear to my cry; hold not your peace at my tears! For I am a sojourner with you, a guest, like all my fathers. Look away from me, that I may smile again, before I depart and am no more!” (vv. 12–13).
Exposition of the Passage
Notice the intensity. David piles up phrases: prayer, cry, tears. He is not uttering cold theology; he is weeping in the presence of his God. He confesses his status: “I am a sojourner with you, a guest, like all my fathers.”
Here David identifies himself with Abraham, Isaac, Jacob, Moses—all who confessed they were strangers and pilgrims on earth (cf. Heb. 11:13). To be a pilgrim means to live as a guest in someone else’s land, dependent on the host’s provision. David recognizes that his life is not his own. He is God’s guest. He is under God’s roof, eating at God’s table, living on God’s earth. His life is a leasehold, not a freehold.
Then comes the striking final plea: “Look away from me, that I may smile again, before I depart and am no more!” This is not unbelief but desperation. David feels crushed under God’s hand and begs for some respite, a little relief before he dies. The psalm ends unresolved, with David still pleading, still longing.
Socio-Historical and Rhetorical Insight
For Israel, this language of pilgrimage was central. Abraham called himself a “sojourner and foreigner” when purchasing a burial plot in Canaan (Gen. 23:4). Israel lived as sojourners in Egypt, then wandered in the wilderness as pilgrims. Even in the Promised Land, God reminded them: “The land is mine, for you are strangers and sojourners with me” (Lev. 25:23).
So David’s words echo Israel’s identity. They are not settlers but pilgrims, guests under God’s roof. The rhetorical effect is humbling: even Israel’s king confesses he is only a guest in God’s house, dependent upon His mercy.
Christ’s Fulfillment
Once again, this longing finds its answer in Christ. Jesus was the ultimate sojourner. The eternal Son left His Father’s house to enter our world. He had no permanent home, no earthly wealth, no place to lay His head (Matt. 8:20). He lived as a stranger among His own creation.
On the cross, He uttered a prayer even more desperate than David’s: “My God, my God, why have you forsaken me?” David cried, “Look away from me, that I may smile again.” Christ bore the full forsaking of God’s gaze, so that God’s face might shine on us in grace.
And because of His resurrection, our pilgrimage is not unresolved. The psalm ends in longing, but Christ brings the answer. He has gone ahead to prepare a place for us (John 14:2–3). We are pilgrims still, but we have a destination secured. Our citizenship is in heaven (Phil. 3:20). Our journey will not end in the grave but in glory.
Searching Applications
- To the aged: You know the reality of pilgrimage more than most. Your tent is fragile; your days are few. But take comfort: your pilgrimage is almost over, and Christ has prepared for you a permanent home.
- To the church: We must not live as though this world were our final dwelling. Do not sink your roots too deep. We are strangers and exiles here. Let us walk lightly, holding earthly possessions loosely, looking to the city whose builder and maker is God.
- To the suffering: Do you pray, “Lord, give me some relief before I die”? David prayed it too. Christ Himself prayed it in Gethsemane. God may grant relief, or He may give strength to endure—but in Christ, either way, your tears are heard, and your end is glory.
- To the careless: If you live as though this world is home, remember—you are only a guest. The breath in your lungs is borrowed air, the land beneath your feet is God’s land, and your soul will soon be required of you. Come to Christ, the only safe dwelling.
Transition to Conclusion
Psalm 39 ends unresolved, with David still pleading, still longing. But that longing is precisely the point. It prepares us for Christ. Where David sighed, Christ fulfills. Where David wept, Christ triumphed. And where David saw only shadows, Christ brings light and life.
Conclusion
Beloved congregation, Psalm 39 has led us down a sobering path.
- We have seen the danger of the tongue, and the wisdom of pouring our grief into prayer rather than into rash speech.
- We have faced the shortness of life, that we are but a handbreadth, a shadow, a vapor.
- We have heard that our afflictions are not random but the Lord’s hand, consuming what we cling to so that we might cling to Him.
- And we have confessed, with David, that we are sojourners and pilgrims on the earth.
But the psalm leaves us with longing. It ends with a plea unanswered: “Look away from me, that I may smile again, before I depart and am no more!” And that is why this psalm drives us to Christ.
In Christ the longing of David finds its resolution.
- He guarded His tongue perfectly, even under mockery and accusation.
- He entered our brevity, living only a short life, yet He rose to secure eternal life.
- He bore God’s rebuke in full, so that our afflictions would never be wrath but fatherly discipline.
- He lived as the ultimate sojourner with no place to lay His head, so that He might bring us to an eternal home.
Where David prayed, Christ fulfilled. Where David longed, Christ answered. Where David saw only shadows, Christ brought light.
So, dear friends, the question of this psalm is the question of your life: “And now, O Lord, for what do I wait? My hope is in you” (v. 7). Is that your confession tonight? Or are you still waiting for wealth, for health, for reputation, for pleasure? All of those are a breath, a shadow. Christ alone is hope that endures.
Searching Exhortations
- To the careless and worldly: Stop living as though this life will never end. Do not heap up riches that death will snatch away. Come to Christ now, before your breath departs.
- To the afflicted and weary: Your tears are not wasted. Your pain is not wrath. Christ bore wrath for you. What you suffer now is the Father’s hand of love, preparing you for glory. Endure in hope.
- To the proud and self-sufficient: Your strength will fade, your beauty will wither, your breath will fail. Humble yourself now before the Lord who gives life and takes it away.
- To the aged: Your pilgrimage is almost complete. Do not fear the end. Christ has gone ahead to prepare a place for you, and soon your faith will be sight.
- To the young: Do not say, “I have plenty of time.” Your life is a mist. Remember your Creator in the days of your youth. Seek Christ now, and you will never regret it.
- To the church together: Let us embrace our identity as pilgrims. We are not settlers in this world. Let us walk together in hope, encouraging one another, until we reach the heavenly city.
Final Pastoral Exhortation
Beloved, life is a handbreadth, a vapor, a shadow. But in Christ, your end is not nothingness—it is glory. So take David’s words upon your lips: “And now, O Lord, for what do I wait? My hope is in you.” Make that your confession tonight, tomorrow, and all the days of your pilgrimage, until you reach the city whose builder and maker is God.
Closing Prayer
O Lord our God,
We thank You for speaking to us through Your servant David. Teach us to number our days that we may gain a heart of wisdom. Forgive us for every idle word, and bridle our tongues by Your Spirit. Remind us daily how brief our life is, and keep us from living for shadows. When Your hand is heavy upon us, help us to submit in faith, knowing that Christ has borne wrath in our place.
Lord Jesus, we thank You that You entered our frailty, bore our rebuke, and opened the way to our eternal home. Fix our eyes upon You as our only hope. Help us to live as pilgrims, not settling in this world, but pressing on to the city that You have prepared.
Father, comfort the afflicted, humble the proud, awaken the careless, strengthen the weary, and draw every heart here tonight to say with David: “And now, O Lord, for what do I wait? My hope is in You.”
We ask this in the name of Jesus Christ, our risen and reigning Savior.
Amen.
