Isaiah 4:24-25
But you have burdened me with your sins; you have wearied me with your iniquities. I, I am he who blots out your transgressions for my own sake, and I will not remember your sins.

And if Christ has not been raised, then our preaching is in vain and your faith is in vain. And if Christ has not been raised, your faith is futile and you are still in your sins.
1 Corinthians 15:14,17
