But forgiveness can’t be proven by our feelings, any more than it can be motivated or empowered by them. Forgiveness is a choice. And feelings often aren’t. It’s quite possible to forgive someone in totally the right way — God’s way — and still have thoughts flash across your mind that completely contradict the decision you made….
But that doesn’t negate what you’ve done. It simply gives you an opportunity to let Him rule over those emotions, to stay the course and keep on forgiving — by faith.
