Psalm 51 New International Version (NIV)

For the director of music. A psalm of David. When the prophet Nathan came to him after David had committed adultery with Bathsheba.

1 Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions.

2 Wash away all my iniquity and cleanse me from my sin.

3 For I know my transgressions, and my sin is always before me.

4 Against you, you only, have I sinned and done what is evil in your sight; so you are right in your verdict and justified when you judge.

5 Surely I was sinful at birth, sinful from the time my mother conceived me.

6 Yet you desired faithfulness even in the womb; you taught me wisdom in that secret place.

7 Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow.

8 Let me hear joy and gladness; let the bones you have crushed rejoice.

9 Hide your face from my sins and blot out all my iniquity.

10 Create in me a pure heart, O God, and renew a steadfast spirit within me.

11 Do not cast me from your presence or take your Holy Spirit from me.

12 Restore to me the joy of your salvation and grant me a willing spirit, to sustain me.

13 Then I will teach transgressors your ways, so that sinners will turn back to you.

14 Deliver me from the guilt of bloodshed, O God, you who are God my Savior, and my tongue will sing of your righteousness.

15 Open my lips, Lord, and my mouth will declare your praise.

16 You do not delight in sacrifice, or I would bring it; you do not take pleasure in burnt offerings.

17 My sacrifice, O God, is a broken spirit; a broken and contrite heart you, God, will not despise.

18 May it please you to prosper Zion, to build up the walls of Jerusalem.

19 Then you will delight in the sacrifices of the righteous, in burnt offerings offered whole; then bulls will be offered on your altar.


is the only hope of the guilty before God.

Big Idea: God is merciful.

God’s mercy is an expression of his (vv. 1-6).

God shows mercy in ways.

  1. He justice as an act of mercy.

“The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance 10 But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.” —2 Peter 3:9-10


2. He forgives unjust as an act of mercy (vv. 2, 7).


“13 Then David said to Nathan, ‘I have sinned against the Lord.’ Nathan replied, ‘The Lord has taken away your sin. You are not going to die.’” —2 Samuel 12:13

God his mercy and justice through the death of Christ.

  • Because Jesus paid for all sin, God’s justice is satisfied.


    “God presented Christ as a sacrifice of atonement… to demonstrate his righteousness at the present time, so as to be just and the one who justifies those who have faith in Jesus.” —Romans 3:25-26

  • Because God’s justice is satisfied, he shows mercy according to his will.

God is rich in mercy but his offer of mercy has an date.

“But because of his great love for us, God, who is rich in mercy, 5 made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved.” —Ephesians 2:4-5

“For many years you were patient with them. By your Spirit you warned them through your prophets. Yet they paid no attention, so you gave them into the hands of the neighboring peoples. 31 But in your great mercy you did not put an end to them or abandon them, for you are a gracious and merciful God.” —Nehemiah 9:30-31

“Who is a God like you, who pardons sin and forgives the transgression of the remnant of his inheritance? You do not stay angry forever but delight to show mercy.” —Micah 7:18

“The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance 10 But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.” —2 Peter 3:9-10

When you receive God’s mercy, it you.

God’s mercy changes the way you think about .

  • It creates which leads to salvation.


    “But because of his great love for us, God, who is rich in mercy, 5 made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved.” —Ephesians 2:4-5


    “Let the wicked forsake their ways and the unrighteous their thoughts. Let them turn to the Lord, and he will have mercy on them, and to our God, for he will freely pardon.” —Isaiah 55:7

  • It calls for and regular .


“Whoever conceals their sins does not prosper, but the one who confesses and renounces them finds mercy.” —Proverbs 28:13

God’s mercy changes the way you think about .

“13 Just as it is written: ‘Jacob I loved, but Esau I hated.’ 14 What then shall we say? Is God unjust? Not at all! 15 For he says to Moses, ‘I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.’ 16 It does not, therefore, depend on human desire or effort, but on God’s mercy. 17 For Scripture says to Pharaoh: ‘I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.’ 18 Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden. 19 One of you will say to me: ‘Then why does God still blame us? For who is able to resist his will?’ 20 But who are you, a human being, to talk back to God? “Shall what is formed say to the one who formed it, ‘Why did you make me like this?’” 21 Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use? 22 What if God, although choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction? 23 What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory— 24 even us, whom he also called, not only from the Jews but also from the Gentiles?” —Romans 9:13-24

God’s mercy changes your .

“But you are a chosen people, a royal priesthood, a holy nation, God’s special possession, that you may declare the praises of him who called you out of darkness into his wonderful light. 10 Once you were not a people, but now you are the people of God; once you had not received mercy, but now you have received mercy.” —1 Peter 2:9-10

“Therefore, I urge you, brothers and sisters, in view of God’s mercy, to offer your bodies as a living sacrifice, holy and pleasing to God—this is your true and proper worship.” —Romans 12:1

God’s mercy calls you to be to others.

“He has shown you, O mortal, what is good. And what does the Lord require of you? To act justly and to love mercy and to walk humbly with your God.” —Micah 6:8

“Blessed are the merciful, for they will be shown mercy.” —Matthew 5:7

“….32 “Then the master called the servant in. ‘You wicked servant,’ he said, ‘I canceled all that debt of yours because you begged me to. 33 Shouldn’t you have had mercy on your fellow servant just as I had on you?’ 34 In anger his master handed him over to the jailers to be tortured, until he should pay back all he owed. 35 This is how my heavenly Father will treat each of you unless you forgive your brother or sister from your heart.” —Matthew 18:21-35

  • Be merciful to others by other sinners about God’s mercy (vv. 9-13).

“Jesus did not let him, but said, ‘Go home to your own people and tell them how much the Lord has done for you, and how he has had mercy on you.’ 20 So the man went away and began to tell in the Decapolis how much Jesus had done for him. And all the people were amazed.” —Mark 5:19-20
