We are righteous. Hell is deserved by other people, not by us. Oh, the blindness of self-righteousness. Let the Word of God tear those blinders from our eyes and prick our hearts. No, you cannot remove your sin.
Sin is an infinite thing.
It is an infinite wrong against God. Sin is so heavy, so lasting in its vileness, that nothing can remove it. Your suffering for it eternally in hell cannot remove it. Only God's mercy can remove it. The offended God must bring my sin to an end.
