COLOSSIANS 3:13 MATTHEW 6:14
We need to forgive others period. No matter what they have done, is it because what they have done is ok, no some things done against are us are horrid and evil, we forgive because God has forgiven us, that is the reason. Forgiveness does not make sin right, but is does let go of the hate, and helps us with our relationship with God and also helps us to move on.
