How about this passage?
John 20:23 "If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained.”
If of any ye may loose the sins, they are [have been] loosed to them; if of any ye may retain, they have been retained.' (Jn. 20:23 YLT)
Forgive what God has forgiven!
