Psalm 51:1 NKJV
Have mercy upon me, O God,
According to Your lovingkindness;
According to the multitude of Your tender mercies,
Blot out my transgressions.
The Power of Mercy: A Return to Faith
MY NOTES
“Have mercy upon me, O God, according to Your lovingkindness; according to the multitude of Your tender mercies, blot out my transgressions.” — Psalm 51:1 (NKJV)
We’ve all been there—that “sinking feeling” in the pit of your stomach when you realize you’ve really, truly blown it. For King David, this wasn’t just a minor slip-up; it was a catastrophic moral collapse. Adultery, murder, and a cold-hearted cover-up that lasted nearly a year. He was “hardened” against repentance until the prophet Nathan called him out with four stinging words: “You are the man!”
But here is where David’s story becomes a masterclass in grace. Once he was shaken, he didn’t run away from God; he ran to Him.
Dropping the Resume Notice what David doesn’t say. He doesn’t mention his “public service” as Israel’s champion. He doesn’t bring up the giant he killed or the Ark he brought back. He drops the crown, the titles, and the excuses. He comes as a man who has stopped self-justifying. He doesn’t ask for mercy because he’s “mostly a good guy”—he asks for it “according to Your lovingkindness.“
His prayer is quite similar to what our Savior says to the penitent publican in the parable: “God be merciful to me a sinner!” (Luke 18:13). David was a man of great worth for many reasons; he had accomplished so much and endured so much for God. Yet, when he realizes he has sinned, he doesn’t try to make up for his wrongdoings by doing good deeds. He also doesn’t believe that his efforts will make up for his mistakes. Instead, he turns to God’s boundless mercy and trusts in it alone for forgiveness and peace: “Have mercy upon me, O God!”
The Mathematics of Mercy David’s plea is perfectly calibrated to his crisis. He uses three specific words to describe what he needs:
- Mercy: God’s assistance to the pitiful.
- Lovingkindness (Hesed): God’s “unfailing love”—the kind of covenant loyalty that stays even when we stray.
- Tender Mercies: This suggests that God actually feels our infirmities. He’s not just a judge; He’s a Father with a broken heart for His broken child.
David was terrified by the multitude of his sins, but he found comfort in the multitude of God’s mercies. It’s a divine math lesson: if your sins are as numerous as the hairs on your head, God’s mercies are as countless as the stars in the sky.
The Red Line through the Black Ledger When David asks God to “blot out” his transgressions, he’s asking for more than a “pass.” He’s asking God to erase the record—to wipe the writing from the ledger of his life. One old commentator puts it beautifully: he’s asking God to cross out the “black lines” of his sin with the “red lines” of Christ’s blood.
Whatever you’re carrying today—whether it’s a big “Corinthian-sized” failure or just the heavy dust of daily mistakes—take a cue from David. Stop the excuses. Stop the running. The God of the multitude of mercies is waiting to pick up the pen and clear the ledger.
Key Takeaways
- Honesty is the Only Path: True repentance means stopping all self-justification. We don’t apologize for our sin; we confess our guilt.
- Hope is Character-Based: David’s hope wasn’t in his ability to do better; it was in God’s Hesed (loyal love). Our security lies in who God is, not what we’ve done.
- Abundance for Abundance: No matter how great the “multitude” of your sins, God has an even greater “multitude” of mercies ready to meet them.
- The Power of “Blotting Out”: God doesn’t just overlook sin; He removes the record of it through the redemptive work of Christ.
Cross References (NKJV)

A Closing Prayer
Abba, I come before You today with no excuses. I don’t want to balance my good deeds against my bad ones. I simply ask for Your mercy—not because I deserve it, but because of Your lovingkindness. Thank You that Your mercies are new every morning and that You delight in blotting out the record of my failures. Thank You for the ‘red lines’ of Jesus that cancel my debt. Help me to live today in the freedom of Your tender compassion. I thank You for this Father in Jesus’ name, Amen.
Some Things to Think About:
- The “Nathan” Moment: When was the last time God “shook” you out of a period of hardness or sin? How did you respond? Did you run toward Him or away?
- Resume vs. Relationship: List three things you’ve ever used to “plead” with God (your service, your church attendance, etc.). Now, cross them out and write “According to Your Lovingkindness” over them.
- The Ledger: Write down the “transgressions” that have been weighing on your mind. Beside them, write “Blotted Out.” What does it look like to truly believe God has erased that record?
- Special Mercy: Thinking of God’s Hesed (loyal love), describe a time when God’s “tender mercies” felt specifically tailored to your infirmity.

Summary of Commentaries:
Crushed by guilt, David abandons all self-justification, appealing solely to God’s hesed—His loyal, covenant-keeping love. Recognizing his “multitude of sins,” he relies on an even greater “multitude of tender mercies” to “blot out” his record of transgression. This prayer represents a total reliance on divine character over personal merit. Like a legal debt erased, David seeks a pardon that only infinite compassion can provide, transforming his brokenness into a powerful testimony of gospel grace.
Commentaries:
Charles Spurgeon
“Have mercy upon me, O God.” He appeals at once to the mercy of God, even before he mentions his sin. The sight of mercy is good for eyes that are sore with penitential weeping. Pardon of sin must ever be an act of pure mercy, and therefore to that attribute the awakened sinner flies.
“According to thy lovingkindness.” Act, O Lord, like thyself; give mercy like thy mercy. Show mercy such as is congruous with thy grace. What a choice word is that of our English version, a rare compound of precious things: love and kindness sweetly blended in one—”lovingkindness.”
“According unto the multitude of thy tender mercies.” Let thy most loving compassions come to me, and make thou thy pardons such as these would suggest. Reveal all thy gentlest attributes in my case, not only in their essence but in their abundance. Numberless have been thine acts of goodness, and vast is thy grace; let me be the object of thine infinite mercy, and repeat it all in me. Make my one case an epitome of all thy tender mercies. By every deed of grace to others I feel encouraged, and I pray thee let me add another and a yet greater one, in my own person, to the long list of thy compassions.
“Blot out my transgressions.” My revolts, my excesses, are all recorded against me; but, Lord, erase the lines. Draw thy pen through the register. Obliterate the record, though now it seems engraven in the rock for ever; many strokes of thy mercy may be needed, to cut out the deep inscription, but then thou has a multitude of mercies, and therefore, I beseech thee, erase my sins. (Spurgeon)

Enduring Word
Have mercy upon me, O God, according to Your lovingkindness: The title of this psalm gives the tragic context for David’s plea. He had sinned in murder, in adultery, in covering his sin, and in hardness against repentance. It took the bold confrontation of Nathan the Prophet to shake him from this (2 Samuel 12); yet once shaken, David came in great honesty and brokenness before God. (Guzik)
i. Have mercy upon me, O God is the prayer of a man who knows he has sinned and has stopped all self-justification. David said to Nathan, I have sinned against the LORD (2 Samuel 12:13) – a good and direct confession, without excuse and with clarity. (Guzik)
ii. David asked for mercy, and that according to the measure of God’s lovingkindness. This is God’s hesed, His loyal love, His covenant mercy. It was a well-phrased request with the eloquence of true brokenness. (Guzik)
According to the multitude of Your tender mercies: In slightly different words, David repeated the thought of the previous appeal. He had before experienced the multitude of God’s tender mercies; he asks for this outpouring again. (Guzik)
i. Multitude of Your tender mercies: “Men are greatly terrified at the multitude of their sins, but here is a comfort – our God hath multitude of mercies. If our sins be in number as the hairs of our head, God’s mercies are as the stars of heaven.” (Symson, cited in Spurgeon)
ii. David used several words to speak of the kindness he desired from God. “Mercy denotes God’s loving assistance to the pitiful. Unfailing love [lovingkindness] points to the continuing operation of this mercy. Compassion [tender mercies] teaches that God feels for our infirmities.” (Boice)
Blot out my transgressions: David felt a register of his many sins condemned him, and he wanted the account of them to be erased. The blotting out may refer to David’s own conscience, or to God’s accounting of sin – or perhaps to both. (Guzik)
i. Blot out my transgressions: “The plea, blot out, means ‘wipe away,’ like the writing from a book (Exodus 32:32; Numbers 5:23).” (Kidner)
ii. Blot out my transgressions: “Out of thy debt-book; cross out the black lines of my sins with the red lines of Christ’s blood; cancel the bond, though written in black and bloody characters.” (Trapp)

Have mercy upon me, O God – This is the utterance of a full heart; a heart crushed and broken by the consciousness of sin. The psalmist had been made to see his great guilt; and his first act is to cry out for mercy. There is no attempt to excuse his sin, or to apologize for it; there is no effort to vindicate his conduct; there is no complaint of the righteousness of that holy law which condemned him. It was “guilt” that was before his mind; guilt only; deep and dreadful guilt. The appeal properly expresses the state of a mind that is overwhelmed at the remembrance of crime, and that comes with earnestness to God to plead for pardon. The only hope of a sinner when crushed with the consciousness of sin is the mercy of God; and the plea for that mercy will be urged in the most earnest and impassioned language that the mind can employ. “Accordingly to thy Iovingkindness.” On the meaning of the word used here, see Psalms 36:7.
(a) The “ground” of his hope was the compassion of God:
(b) the “measure” of that hope was His boundless beneficence; or, in other words, he felt that there was need of “all” the compassion of a God.
His sin was so great, his offense was so aggravated, that he could have no hope but in a Being of infinite compassion, and he felt that the need of mercy in his case could be measured and covered “only” by that infinite compassion.
According unto the multitude of thy tender mercies – The same idea occurs here also. The psalmist fixed his eye on the “vastness” of the divine mercy; on the numberless “acts” of that mercy toward the guilty; here he found his hope, and here alone. Every instance of extraordinary mercy which had occurred in the world furnished him now with an argument in his appeal to God; was an encouragement to him “in” that appeal; was a ground of hope that his appeal would not be rejected. So to us: every instance in which a great sinner has been forgiven is evidence that we may be forgiven also, and is an encouragement to us to come to God for pardon. See 1 Timothy 1:16.
Blot out my transgressions – In allusion to an account that is kept, or a charge made, when such an account is wiped away, erased, or blotted out. Compare Exodus 32:32-33; see the notes at Isaiah 43:25; notes at Isaiah 44:22; notes at Colossians 2:14. Never was a more earnest appeal made by a sinner than that which is made in this verse; never was there a more sincere cry for mercy. It shows us where we should “begin” in our prayers when we are pressed down with the consciousness of sin – with a cry for “mercy,” and not an appeal to “justice;” it shows us what is to be the “ground” and the “measure” of our hope – the mere compassion of an infinitely benevolent God; it shows us the place which we must take, and the argument on which we must rely – a place among sinners, and an argument that God has been merciful to great sinners, and that therefore he may be merciful to us.

Have mercy upon me, O God,…. David, under a sense of sin, does not run away from God, but applies unto him, and casts himself at his feet, and upon his mercy; which shows the view he had of his miserable condition, and that he saw there was mercy in God, which gave him hope; and upon his bended knees, and in the exercise of faith, he asks for it;
according to thy lovingkindness; not according to his merits, nor according to the general mercy of God, which carnal men rely upon; but according to his everlasting and unchangeable love in Christ; from which as the source, and through whom as the medium, special mercy comes to the children of men. The acts of special mercy are according to the sovereign will of God: he is not moved to mercy neither by the merits nor misery of men, but by his free grace and favour; it is love that sets mercy to work: this is a most glaring gleam of Gospel light, which none of the inspired writers besides, except the Apostle Paul, saw, Ephesians 2:4;
according unto the multitude of thy tender mercies blot out my transgressions; for his sin was complicated, attended with many others; and, besides, upon a view of this, he was led to observe all his other sins; and particularly the corruption of his nature, his original sin, which he mentions, Psalm 51:5. These he desires might be “blotted out”; out of the book of account, out of God’s debt book; that they might not stand against him, being debts he was not able to pay or make satisfaction for; and out of the table of his own heart and conscience, where they were ever before him, and seemed to be engraven; that they might be caused to pass from him, and he might have no more conscience of them; or that they might be blotted out, as a cloud by the clear shining of the sun of righteousness, with the healing of pardoning grace in his wings; or that they might be wiped away, as any faith is wiped from any person or thing: and all this “according to the multitude of [his] tender mercies.” The mercy of God is plenteous and abundant; he is rich in it, and various are the instances of it; and it is exceeding tender, like that of a father to his children, or like that of a mother to the son of her womb; and from this abundant and tender mercy springs the forgiveness of sin, Luke 1:77. The psalmist makes mention of the multitude of the mercies of God, because of the multitude of his sins, which required a multitude of mercy to forgive, and to encourage his hope of it.

Matthew Henry
His prayer is much the same with that which our Savior puts into the mouth of his penitent publican in the parable: God be merciful to me a sinner! Lu. 18:13. David was, upon many accounts, a man of great merit; he had not only done much, but suffered much, in the cause of God; and yet, when he is convinced of sin, he does not offer to balance his evil deeds with his good deeds, nor can he think that his services will atone for his offenses; but he flies to God’s infinite mercy, and depends upon that only for pardon and peace: Have mercy upon me, O God! He owns himself obnoxious to God’s justice, and therefore casts himself upon his mercy; and it is certain that the best man in the world will be undone if God be not merciful to him. Observe,
What his plea is for this mercy: “have mercy upon me, O God! not according to the dignity of my birth, as descended from the prince of the tribe of Judah, not according to my public services as Israel’s champion, or my public honors as Israel’s king;” his plea is not, Lord, remember David and all his afflictions, how he vowed to build a place for the ark (Ps. 132:1, 2); a true penitent will make no mention of any such thing; but “Have mercy upon me for mercy’s sake. I have nothing to plead with thee but,”
(1.) “The freeness of thy mercy, according to thy lovingkindness, thy clemency, the goodness of thy nature, which inclines thee to pity the miserable.”
(2.) “The fulness of thy mercy. There are in thee not only lovingkindness and tender mercies, but abundance of them, a multitude of tender mercies for the forgiveness of many sinners, of many sins, to multiply pardons as we multiply transgressions.”

Miscellaneous Comments
“MY transgressions.” Conscience, when it is healthy, ever speaks thus: “MY transgressions.” It is not the guilt of them that tempted you: they have theirs; but each as a separate agent, has his own degree of guilt. Yours is your own: the violation of your own and not another’s sense of duty; solitary, awful, unshared, adhering to you alone of all the spirits of the universe.
