Sin is ever-present in man and allows evil to work in us. We cannot destroy sin, nor can we pay it back in kind - it is only Christ who pays it back in full for us.
What we can do to is to seek repentance. In repenting, we do not just correct our wrongdoings, nor do we just seek to do good. Instead, we realise that we have already been redeemed, and in receiving God’s grace and love, we learn to hate and reject sin.
