Living Inside Psalm 51: A Conversation with David Roseberry
A Conversation with David Roseberry and Peter Johnston
Peter: David, I’m glad to share the background of your new book, Create In Me A Clean Heart: Experience God’s Love, Personal Renewal, and Ultimate Joy, with our readers—not only so they can buy it (available on Amazon here), but most of all so they can discover Psalm 51 afresh (the full text of the psalm is at the end of this article). It really is one of the most powerful psalms, and one that we read every year on Ash Wednesday.

So what was it like for you to write a book about this Psalm?
David: It was unsettling in the best possible way. I thought I knew Psalm 51. I knew it liturgically. I’d prayed it every Ash Wednesday for years. I knew the famous lines—“Create in me a clean heart, O God,” “O Lord, open my lips.” I had even assigned it at retreats as a way for people to reckon with their sins.
But living inside it—slowly, verse by verse—was something else entirely. It stopped feeling familiar once I moved past the one-liners. King David isn’t wrestling abstractly with sin. He’s been found out. He’s stopped defending himself.
As Evelyn Underhill puts it, he’s standing unprotected before God. That idea changes everything.
Reading the Whole Psalm 51
Peter: You’ve said that the psalm surprised you, especially toward the end. What do you mean by that?
David: I realized, almost to my shock, that I had only ever read part of Psalm 51. Both the 1979 and 2019 Books of Common Prayer omit the final verses from the Ash Wednesday liturgy—the verses about sacrifice and restoration. I understand why, but reading the psalm as a whole made it more compelling, not less.
At the end, King David still doesn’t have the answer to his most urgent question. He knows God is merciful. He knows sacrifice alone won’t do. But like Job before him, he seems to ask: Is there someone who can stand between God and me? (Job 9:33) He is looking for an arbiter. An umpire. Someone like God enough to represent Him, and like me enough to understand me.
That unresolved tension isn’t a flaw. To me, it is part of the psalm’s power. It prepares us for Holy Week without knowing its name.
In a sense, Psalm 51 is emblematic of the Old Testament. It struggles with sin and the distance it creates from God—a distance King David is very nervous about personally experiencing—but it doesn’t offer a path to reunion and redemption except through the offering described at the end of the Psalm.
King David is on the precipice, looking into Holy Week, almost. He sees the need, but he just can’t get there on his own.
Repenting and Forgiving
Peter: Your book also makes space for people who have been sinned against, not just those confessing sin. Why was that important?
David: Because forgiveness isn’t simple. We say it easily: “Forgive us our sins as we forgive those who sin against us.” But forgiveness is not easy. I wanted to be careful not to turn repentance into something cruel.
Psalm 51 is spoken in the voice of the sinner, but many people hear it through the echo of someone else’s sin. I wanted readers to know: God does not confuse guilt with grief. He does not rush healing. Repentance and forgiveness are often long obedience, not single moments.
Taking Time To Digest
Peter: What’s the best way to read Psalm 51?
David: You have to read it slowly, like a rich meal, taking time to digest.
As a pastor and writer, there’s always the danger that you prepare food for others without eating it yourself. You study, explain, and teach, but forget to digest.
Psalm 51 wouldn’t let me do that. It demanded time. Slowness. Attention. I kept asking myself whether I was reading it the way Cranmer intended: read, mark, learn, and inwardly digest.
This book is different for me. I don’t feel like I skimmed the surface. I feel like the psalm did its work on me before I ever tried to pass it on.
Peter: So what do you ultimately want readers to take away from this book?
David: I want them to use it.
Very practically, yes—I hope they buy the book. It’s in paperback because I want people to write in it, underline it, mark it up. There’s also a hardcover for those who want to keep it long-term.
But more than that, I want people to walk with Psalm 51 through Lent. For those who want to go deeper, I’ll be sending daily reflections to paid Substack subscribers every morning at 6:12 AM Central—verse by verse, day by day. You can join for a month and walk the season with me.
Psalm 51 has drawn some of the Church’s greatest minds—Augustine, Luther, Spurgeon, N. T. Wright—because it tells the truth without shortcuts and holds mercy without denial. My hope is that readers discover what they discovered: repentance is not self-improvement. It is return.
And return is always met by mercy.
Psalm 51 (ESV)
To the choirmaster. A Psalm of David, when Nathan the prophet went to him, after he had gone in to Bathsheba.
Have mercy on me, O God,
according to your steadfast love;
according to your abundant mercy
blot out my transgressions.
Wash me thoroughly from my iniquity,
and cleanse me from my sin!
For I know my transgressions,
and my sin is ever before me.
Against you, you only, have I sinned
and done what is evil in your sight,
so that you may be justified in your words
and blameless in your judgment.
Behold, I was brought forth in iniquity,
and in sin did my mother conceive me.
Behold, you delight in truth in the inward being,
and you teach me wisdom in the secret heart.
Purge me with hyssop, and I shall be clean;
wash me, and I shall be whiter than snow.
Let me hear joy and gladness;
let the bones that you have broken rejoice.
Hide your face from my sins,
and blot out all my iniquities.
Create in me a clean heart, O God,
and renew a right spirit within me.
Cast me not away from your presence,
and take not your Holy Spirit from me.
Restore to me the joy of your salvation,
and uphold me with a willing spirit.
Then I will teach transgressors your ways,
and sinners will return to you.
Deliver me from bloodguiltiness, O God,
O God of my salvation,
and my tongue will sing aloud of your righteousness.
O Lord, open my lips,
and my mouth will declare your praise.
For you will not delight in sacrifice, or I would give it;
you will not be pleased with a burnt offering.
The sacrifices of God are a broken spirit;
a broken and contrite heart, O God, you will not despise.
Do good to Zion in your good pleasure;
build up the walls of Jerusalem;
then will you delight in right sacrifices,
in burnt offerings and whole burnt offerings;
then bulls will be offered on your altar.
