You don't forgive for the OTHER person. You forgive for YOURSELF. Who cares if the other person knows or not if you've forgiven them. Chances are they couldn't care less. We need to forgive for our OWN sake. If we don't, we'll eat ourselves alive. "Resentment is the poison I take to kill you." And it's true. The people we resent don't have a CLUE that we resent them. They don't care!! They're off living their own little lives, while we're at home killing ourselves with our resentments!!
WE MUST forgive others so keep ourselves healthy mentally and physically! That doesn't mean we have to ask them to dinner. LOL It just means we need to forgive them for what they've done -- and get on with OUR lives.

It IS divine to forgive.
Take care and God bless. Big hugs, Lee
