Cleansing by the Appointed Means

layers Part 8 of 16 menu_book More on Psalms lightbulb 9 illustrations in this sermon

Pastor Albert N. Martin expounds Psalm 51:7, 'Purge me with hyssop, and I shall be clean; wash me, and I shall be whiter than snow,' as a model for repentance. He argues that true confession involves a deep understanding of sin's defiling nature and a plea for cleansing through the appointed means: the atoning blood of Christ and the purifying work of the Holy Spirit. Martin emphasizes that sin defiles believers, bars them from realized fellowship with God, and that the blood of Christ is the only refuge for the sinning saint, urging believers to forsake self-righteous efforts and cling to Christ alone for cleansing and access to God.

Key Quotes

“One of the greatest factors involved in a life of increasing Christian maturity is the ability to scripturally deal with sin.”
“So, when we come to confess, let us never feel, that if we find ourselves confessing to God certain things that we've already confessed, or pleading with God for certain things we've already pled for, let's not be condemned with a wrong sense of condemnation that this is vain repetition.”
“Purify me by the appointed means. This is the core of David's prayer.”
“No, I would remind you that sin is always ugly to God. The difference is, we shall not be brought under the legal condemnation of our sin.”
“If you've never been troubled with the problem of whether or not you should reconfess something, I doubt that you've ever truly confessed anything.”
“A Christian is content with nothing less than the realized experience of the presence of God.”
“Oh, dear child of God, may I purge you and exhort you to learn the lesson that I am so painfully slow at learning, that all my groaning and moaning won't purge away my evil conscience.”

Applications

All listeners

  • Study David's model of repentance so that you, by the grace of God, may know the same kind of repentance when you, like David, have sinned.
  • Enter more and more into the closet life of your own individual experience, Monday through Saturday, to the spirit of Psalm 51, praying it with greater understanding and heart involvement.
  • When you come to confess, never feel condemned that confessing things you've already confessed, or pleading for things you've already pled for, is vain repetition.
  • Recognize that when you, as a Christian, sin, you are polluted and defiled by that sin, and need to pray as David did, 'Purge me with hyssop,' pleading for a fresh application of the blood of Christ.
  • Confess your sin to God, crying out 'Purge me with hyssop,' and cleanse me by the blood of Christ, again.
  • Examine whether you have known at least something of the realized presence of God in the past week, and if not, consider the role of unconfessed sin.
  • Learn that all your groaning, moaning, flagellating yourself, or trying to appease God with works will not purge away your evil conscience or give you boldness of access; only the sprinkling of the blood of Christ will.
  • Come to the cross 'just as I am, without one plea, but that thy blood was shed for me,' clinging simply to Christ.
  • Overcome the human heart's tendency to build up its own merit and trust solely in the blood of Christ for cleansing.
  • Acknowledge your sins and plead to the only source of forgiveness, even Jesus Christ, to know the forgiveness of your sins.
