This is such a hard thing to do, but as I read this on Saturday morning I was reminded that we forgive, extend grace, etc, not because a person is worthy of it. We do those things for God's sake - because He asks us to. Ultimately it is for our good, as well.
He reveals Himself to us in each situation that comes our way -
"I am your healer"
"I am your protector"
I am your comfort"
"I am your father"
"I am your friend"
What a precious gift of Himself He gives to us.
