How Can The All Knowing God No Longer Remember Our Sins?
How can God who sees all things, no longer see sin in believers? The Lord Jesus Christ is the answer. The Messiah (Hebrew word for Christ), of whom Daniel wrote, was, “To finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness” (Daniel 9:24). To make an end of sins! The Lord Jesus Christ has so effectually redeemed His people, so perfectly reconciled His people, so absolutely propitiated God, so thoroughly removed the sins of His people – that God declares – the God who cannot change – “Their sins and iniquities will I remember no more” (Hebrews 10:17). “There is therefore now no condemnation to them which are in Christ Jesus” (Romans 8:1). In Christ, He sees us in Christ, in the Beloved, “In whom He is well pleased.”
Every child of God needs to realize the fact that at this very moment all of his sins are gone – effectually, completely, perfectly gone – through the great sacrifice of the Lord Jesus Christ. All of your sins, from the cradle to the grave, sins before conversion and sins after conversion, and sins of every kind are washed away in Immanuel’s precious blood.
Since Christ has died in our stead, under the sentence of God’s law, we shall never be charged with sin. God has removed our sins from His book, from His memory, and from us. In Christ we have been freed from sin. “As far as the east is from the west, so far hath he removed our transgressions from us.” (Psalm 103:12)
“I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins.” (Isaiah 43:25)
“Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of hos heritage? he retaineth not hos anger for ever, because he delights in mercy. 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 7:18-19)
“In those days, and in that time, saith the LORD, the iniquity of Israel shall be sought for, and there shall be none found: for I will pardon them whom I reserve.” (Jeremiah 50:20)
Where are the sins of God’s people?
Hezekiah says: “Behold, for peace I had great bitterness: but thou hast in love to my soul delivered it from the pit of corruption: for thou hast cast all my sins behind thy back.” (Isaiah 38:17)
Amen!

“Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing. And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.” (Revelation 5:12-13) Amen! :)
