In this eleventh sermon on Psalm 51, Pastor Albert N. Martin expounds verse 10, "Create in me a clean heart, O God, and renew a right spirit within me." He argues that David's prayer reveals the completeness of true repentance, addressing both the legal guilt and the moral pollution of sin, and highlights the essential inwardness of the Christian life. Martin emphasizes that only God's sovereign power can create a clean heart and renew a steadfast spirit, urging believers to pursue perfection in heart purity while acknowledging its full attainment is only in glory, and calling unbelievers to flee to Christ for both forgiveness and a new heart.

Key Quotes

“As David was a tragic example of how a most privileged child of God can become a most shameful sinner, so David is also a beautiful example of how a shameful sinner can become a most shameful sinner. A shameful sinner becomes a model of penitence and confession.”
“Abraham and David and the other saints of God whose sins are not by any means covered up or glossed over in the scripture but laid out clearly, the scripture makes clear that they sinned and sinned against the basic bent and direction of their own renewed desires. They sinned in their weakness, but to sin with a high hand and with impunity is to mark oneself as an unregenerate man.”
“David's prayer was a complete prayer. For in his confession and in his seeking the face of God for mercy, he did not stop short of pleading for those two basic needs, that sin always creates in the life of a believer or an unbeliever. A legal problem and a personal moral problem.”
“But the man or woman who is a true child of God, is not content with simply legal acceptance. He longs for personal experience of the presence of God, and he knows that this cannot be experienced unless he has a clean heart.”
“Fear a cold heart to Christ like you would fear open denial of him as Peter was guilty. Fear a cold heart like you would fear apostasy. For the first step to apostasy, to open denial, to open breach of the law of God is a cold heart.”
“But though I had power to forfeit these things, I have no power to restore them. And nothing short of the exercise of omnipotence can meet my need.”
“Again, I say, as I've said on other nights, this psalm is one that only the person smitten with a sense of his sin can truly understand. You've got to come at it heart first, with your head tagging along. If you come to it head first, you'll never understand it.”
“So when David is conscious of sin, he doesn't pray, creating me a half-clean heart, creating me a three-quarters clean heart, but, O God, creating me a heart that is nothing but cleanliness and purity. For if the heart is all pure, then the life will be all pure. For out of the heart are the issues of life.”

Applications

All listeners

  • Seek to avoid David's example of sin, but emulate his example of repentance.
  • If you are outside of Jesus Christ, you cannot begin to cope with impurity of thought and unholy desires until you are restored to God through Christ's blood and brought into a justified state.
  • When we have sinned, we must come first of all crying as David did, 'Blot out!' and then 'Create in me.'
  • Do not be content with simply knowing your record is set right; long for personal and moral purification of your heart.
  • If God has given you a clear word about some area of your life (e.g., finances, hidden sin, attitude, relationships) and you are not steadfast in obeying Him, there will be a breakdown that issues in other sin.
  • Guard your heart. Fear a cold heart like you would fear a fall into open immorality, open denial of Christ, or apostasy.
  • May God grant that we shall follow David's example in being concerned about the inward parts.
  • If you are a stranger to the grace of God, repent, believe the gospel, and flee to Christ. He will not only blot out your sins but change your heart and give you a desire to obey Him.
  • Let us not be content to know that God's wrath is turned away when we've confessed our sin, but let us pray that there be a purging, a renewing of the inner man as well.
  • Take time to guard your heart. Trace your sins back to their first spring in the heart. Do not rest short of pleading with God for cleansing of the heart and renewing of a steadfast spirit.
