then he adds, “I will remember their sins and their lawless deeds no more.” Where there is forgiveness of these, there is no longer any offering for sin. (Heb. 10:17-18)
The New Covenant promise that God will “remember our sins no more” means that the whole category of “sins” is gone forever from God’s sight, as far as the law and satisfaction of justice are concerned. Believers have been “made prefect” as to their consciences and are no longer to have “consciousness of sin” with regard to the wrath of God! In this sense, there is “no more reminder of sin” (Heb. 10:3) in the New Covenant. “Now where there is forgiveness of these things, there is no longer any offering for sin.” (Heb. 10:18) “We have been sanctified through the offering of the body of Jesus Christ once for all.” (Heb. 10:10)
What does this mean in daily life? It means that, as a Christian, I can get up in the morning and know that I am accepted in Christ. God delights in me as His child, and the guilt of my sins is gone forever. If I commit a sin, I am “conscious” of my sin as a child, not as a convicted felon, and I confess my sin to God as a son confesses to his Father, not as a criminal confesses to a judge. I come with confidence into the holy place by the blood of Jesus.
