A Christian friend doesn’t understand how forgiving someone can help free him. I’d said “The moment you can truly forgive (Matthew 5:44 Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you) is the moment the doors will open and you’ll be set free.” I say it works because no one can weave with you a bond of hatred if you contribute no strands to the weaving. Let it ALL go and your cork will bob to the surface in a heartbeat.
