What Is the Unforgivable Sin? Understanding God’s Promise of Forgiveness

I don’t know who needs to read this; I just know that many do.

Do you know what the unforgivable sin is? 

The only unforgivable sin is rejecting the forgiveness of God.

So embrace that forgiveness.

Here’s what God promises about that forgiveness. First, God promises to forget about your sin. This is what the Bible records God saying through the prophet Jeremiah: “I’ll wipe the slate clean for each of them. I’ll forget they ever sinned!” (Jer. 31:34).

That’s right. When you are forgiven, God gets a case of holy amnesia. You may have gone to God a thousand times to ask for forgiveness of a sin that he forgot about after the first time you asked him to forgive you. Or maybe you’ve repeated a particular sin over and over, and you go to God and say, “God, I’m so sorry—I did it again.” And he’s asking, “Did what?”

When God forgives, he chooses to forget.

But that’s not all.

God doesn’t just forget; he promises to cleanse you from it. In his eyes, forgiveness completely purifies and cleanses you. Read these words from God through the prophet Isaiah:

“Though your sins are like scarlet, I will make them as white as snow. Though they are red like crimson, I will make them as white as wool” (Isa. 1:18).

But that’s not all. There’s more. God promises to remove your sin from your record. This is how the Bible puts it:

“He has removed our sins as far from us as the east is from the west” (Ps. 103:12).

Once you are forgiven by God, your sins are gone. They are cast away. They are never able to come back and haunt you, accuse you, nor condemn you. As Corrie ten Boom once said, when God forgives us, he takes our sins to the deepest part of the ocean, attaches a large weight, drops them overboard, and puts up a “No Fishing” sign.
