Purge me with hyssop, and I will be clean; wash me, and I will be whiter than snow.
— Psalm 51:7
We must come and ask God to cleanse us in every part of our being. Many people forget that even their memory is tainted by its intimate connection with the old self. All manner of sin has been brought into the sanctuary of the mind. Our memory needs to be cleansed. Have you ever asked God to cleanse your memory from all of the evil stored there? Our affections need to be cleansed and purified. Our wills need to be cleansed.
We need to realize that only through the blood of Christ is there cleansing for sin. “What can wash away my sin? Nothing but the blood of Jesus.”
If we are going to come into the presence of God and expect Him to hear and answer our prayers, we dare not come into His presence besmirched and befouled and tainted with our sins.
“Cleanse me, O God!” That means, of course, that we are going to confess our sins and repent of them as well as ask to be cleansed from them.
