He will turn again, He will have compassion upon us; He will subdue our iniquities; and Thou wilt cast all their sins into the depths of the sea. – Micah 7:19

As soon as a man believeth in Christ Jesus, his sins are gone from him, and gone away for ever. They are blotted out now. What if a man owe a hundred pounds, yet if he has got a receipt for it, he is free; it is blotted out; there is an erasure made in the book, and the debt is gone. Though the man commit sin, yet the debt having been paid before even the debt was acquired, he is no more a debtor to the law of God. Doth not Scripture say, that God has cast His people’s sins into the depths of the sea? Now, if they are in the depths of the sea, they cannot be on His people too. Blessed be His name, in the day when He casts our sins into the depth of the sea, He views us as pure in His sight, and we stand accepted in the Beloved. Then He says, “As far as the east is from the west, so far hath He removed our transgressions from us.” They cannot be removed and be here still. Then if thou believest in Christ, thou art no more in the sight of God a sinner; thou art accepted as though thou wert perfect, as though thou hadst kept the law for Christ has kept it, and His righteousness is thine. You have broken it, but your sin is His, and He has been punished for it. Mistake not yourselves any longer; you are no more what you were; when you believe, you stand in Christ’s stead, even as Christ of old stood in your stead. The transformation is complete, the exchange is positive and eternal. They who believe in Jesus are as much accepted of God the Father as even His Eternal Son is accepted; and they that believe not, let them do what they will, they shall but go about to work out their own righteousness; but they abide under the law, and still shall they be under the curse. Now, ye that believe in Jesus, walk up and down the earth in the glory of this great truth. You are sinners in yourselves, but you are washed in the blood of Christ.~ C.H. Spurgeon
