Psalm 51: Create in Me a Clean Heart

Passage: Psalm 51

The Big Idea

David wrote Psalm 51 after Nathan confronted him about his adultery with Bathsheba and the murder of Uriah. It’s the great prayer of repentance. David doesn’t plead his record; he pleads God’s lovingkindness and mercy. He asks not for reform but for a new creation: a clean heart and a steadfast spirit. And he discovers the sacrifice God won’t despise: a broken and contrite heart.

Reflections

Have mercy upon me, O God, according to Your lovingkindness (v. 1). As a guilty person, it’s hard to believe I can ask a holy God for mercy. But that’s grace: You give mercy to the undeserving and give what I could never earn. The reason isn’t that I’m good or deserving, but Your lovingkindness and the multitude of Your tender mercies. Jesus, You’re full of grace. I plead Your blood: Your mercy, grace and life poured out for me.

Wash me thoroughly (v. 2). I need You to do the washing, inside and out. I feel dirty and ashamed. There’s a stain on my heart only Your blood can remove.

I acknowledge my transgressions (v. 3). I confess everything. You’re the only one I trust with how bad it is inside, yet it scares me to be that open. What if You reject me? But You’ve promised never to reject the humble and broken. What if I’m not humble enough, or sorry enough? My sin is always before me; Your Spirit convicts me. Make me even more sensitive to Your holiness.

Against You, You only, have I sinned (v. 4). You’ve surrounded me with people, but ultimately I deal with You. If everyone were taken away, I’d still have You. And I’ve hurt You. Forgive me and receive me. You’d be right to judge me completely, yet You chose to put all that judgment on Jesus. Help me see it and believe it.

I was brought forth in iniquity (vv. 5-6). Rebellion has been my path since birth; it’s the nature I inherited from Adam. You desire truth in the inward parts. Your mission is to transform that nature, so that I know truth, do truth and, as Your child, by nature do what pleases my Father.

Purge me with hyssop, and I shall be clean (v. 7). Only the blood can change me, forgive me and give me confidence. I shall be whiter than snow. Jesus, I receive Your precious blood by faith.

Make me hear joy and gladness (v. 8). I want to hear the joy of a family that knows You. I have no greater joy than to hear that my children walk in truth (3 John 4). I’m asking for that.

Hide Your face from my sins, and blot out all my iniquities (v. 9). I haven’t been good, not even OK. Don’t deal with me according to my failures. Do what I never could: make me as if I’d never sinned. Only grace can do this.

Create in me a clean heart, O God, and renew a steadfast spirit within me (v. 10). I need a new creation, not a reformed old heart. A new spirit, Your Spirit. Teach me to depend on and walk in the Spirit, with a steadfast connection that doesn’t flicker.

Do not cast me away from Your presence (v. 11). You’d have every right. But I need Your mercy to abide, and Your help when I fail. Your adoption comforts me. Cast the evil out of my heart instead. Let Your refining fire drive out fear and deceit, and let the fruit of the Spirit grow. I don’t want this relationship of love to end. I want to know how much You love me and love You as You deserve.

Restore to me the joy of Your salvation (v. 12). Joy is normal for someone forgiven and set free. I feel it’s gone, and I need to remember what You’ve done. Your salvation: that’s where all joy is found, not in what I’ve done, have or hope for, but in what You accomplished at the cross. Uphold me by Your generous Spirit. I can’t hold myself up. And Your Spirit is genuinely generous: You delight to provide everything, even in the furnace of trial, even when I’m broken, doubtful or selfish. You love to give.

Then I will teach transgressors Your ways (v. 13). Jesus, let the mercy You’ve poured into my life be used for Your kingdom, to encourage people You love. Transgressors and sinners: that’s who I’m praying for. Pour Your living water into me so others are refreshed.

Deliver me from the guilt of bloodshed (v. 14). Guilt is something to be saved from, and that’s what the Savior does. My tongue shall sing aloud of Your righteousness. You reach out to me when I’m dead and distant, bring me back when I run, forgive and restore.

O Lord, open my lips (v. 15). I’ll wait for You to open them. If I force it, it’s self-sourced. My lips are shut with shame. I need Your Spirit’s washing and resurrection; then praise will flow.

You do not desire sacrifice (vv. 16-17). My works aren’t what You’re after. You love me for Your own reasons; my efforts don’t make a dent. The sacrifices of God are a broken spirit, a broken and contrite heart; these, O God, You will not despise. You like those. So I’ll bring them.

Do good in Your good pleasure to Zion (vv. 18-19). You love to do good, even to me. I need You to build my walls before I can do anything right. I can’t offer any sacrifice until Your sacrifice has done its full work in me. Waiting on the Lord isn’t just letting time pass; it’s humbly placing my hope in Him while time passes.

Grace Takeaway

You don’t need to clean yourself up before you come. Come broken. Ask Him to wash you, create a clean heart in you, and restore the joy of His salvation. A broken and contrite heart, He will not despise.
