Forgiveness of Sins Through the Blood: What the Bible Actually Says

Mike Mahaffey

Forgiveness of sins through the blood of Jesus is not a pardon. A pardon leaves the offense on the record and cancels the penalty. What the blood accomplished is something different — the sin itself is removed. Gone. That is what the Bible calls remission, and it is the only basis on which God forgives. (Ephesians 1:7; Hebrews 9:22)

What Does “Forgiveness of Sins” Actually Mean?

Most people hear “forgiveness” and think of a judge deciding not to punish someone. The offense still happened. The record still exists. The judge simply chose not to act on it. That is pardon.

The Bible does not use pardon language when it describes what the blood of Jesus accomplishes. It uses a different word entirely: remission.

Remission means the thing is sent away. Not filed away. Not sealed behind a decision. Sent. Away.

The writer of Hebrews makes this the structural rule of the entire sacrificial system:

And almost all things are by the law purged with blood; and without shedding of blood is no remission. (Hebrews 9:22)

There is no remission without blood. That is not a statement about God’s preferences. It is a statement about how sin is dealt with. The blood does not prompt a decision from God — it accomplishes a removal.

These are two different things, and the difference matters.

What Does the Blood Have to Do with It?

Paul connects the blood directly to forgiveness in the first chapter of Ephesians. Not as background. Not as context. As the mechanism.

In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace. (Ephesians 1:7)

The phrase “in whom” refers to Christ. The word “redemption” means a buying back — the image is a slave market. And tied directly to that redemption, through that same blood, is the forgiveness of sins. These are not two separate transactions. They happen together, through the blood, in Christ.

This is why the Cross is not incidental. You cannot separate forgiveness from the blood and have the same thing left over. Remove the blood, and you have no remission — Hebrews 9:22 makes that plain. The blood is not the occasion for forgiveness. It is the basis of it — one of seven distinct things the blood of Jesus accomplished at the Cross.

What Happened to the Record?

Paul describes what the Cross did to the written charge against us with striking specificity.

And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross. (Colossians 2:13–14)

“Blotting out” is not sealing. It is not archiving. It is erasure. The record is destroyed. And the method Paul describes is precise — it was nailed to the cross. Not stored somewhere sealed. Nailed there. The thing that stood against you was taken to the Cross and killed there.

The word “blotting out” in the Greek carries the image of washing a document clean — the text removed so thoroughly that the surface could be written on again. That is what God did with the record of your sin through the blood of His Son.

Does God Still Remember What Was Forgiven?

This is where many believers get stuck. They understand intellectually that sin is forgiven. But they still carry the weight of it. They assume that even if God chose not to punish, He still knows — still sees the record, still recalls the offense.

That assumption is precisely what the New Covenant addresses. God did not simply decide to look the other way. He made a promise about what He will no longer do:

And their sins and iniquities will I remember no more. (Hebrews 10:17)

God does not just refrain from punishing. He no longer recalls. This is a different category entirely from legal pardon. A judge who pardons still has full knowledge of what was pardoned. What God describes here is not forbearance — it is a complete severing of the sin from the record.

David expressed the same truth in the Psalms:

As far as the east is from the west, so far hath he removed our transgressions from us. (Psalm 103:12)

East from west has no closing point. You can travel north until north becomes south — the poles exist. But east never becomes west. The removal is without limit and without reversal.

This is a description of what actually happened when the blood was shed.

Is the Blood Still Working Today?

The New Testament does not speak of the blood only in the past tense. John makes this plain in his first epistle.

But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. (1 John 1:7)

Cleanseth — present tense. Not “cleansed” as a finished event only. The blood is active now. It is not a historical transaction that closed at Calvary and now exists only as a record. It is the present, ongoing basis on which the believer stands before God.

This does not mean sin is cleansed automatically or apart from faith. John is writing to believers walking in the light — people whose faith is placed in Christ and what He accomplished. For those people, the blood is not a past event they look back on. It is a present reality they stand in.

The ongoing nature of what the blood does has deep application for the believer’s daily life — for prayer, for conscience, for authority over sin.

But the foundation has to be secure first: the blood accomplished a real removal, not a legal adjustment. That removal is complete. It is permanent. And it is still in force today.
