It turns out Jesus doesn’t forgive people’s sins; his followers do (or are supposed to).

So Jesus said to them again, “Peace be with you. Just as the Father has sent me, I also send you.” And after he said this, he breathed on them and said, “Receive the Holy Spirit. If you forgive anyone’s sins, they are forgiven; if you retain anyone’s sins, they are retained.”

John 20:21-23 NET
