Ezekiel 18:21-23
King James Version
21 But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
22 All his transgressions that he hath committed, they shall not be mentioned unto him: in his righteousness that he hath done he shall live.
23 Have I any pleasure at all that the wicked should die? saith the Lord God: and not that he should return from his ways, and live?
I remember feeling a lot of shame in my life at one point. How could I move on? But when I read these verses, it freed me.
I knew that if I turned to God that day and stopped backsliding, Id be saved. It really is simple. God is not interested in holding our past mistakes against us if we just turn to Him and obey Him from now on.
