If you’re rehashing the same hurt every chance you get with anyone who will listen, I have a question: why are you doing God’s work for him? “Vengeance is mine,” God declared. “I will repay” (Hebrews 10:30). To assume otherwise is to assume God can’t do it. When we strike back we are saying, “I know vengeance is yours, God, but I just didn’t think you’d punish enough. I thought I’d better take this situation into my own hands.”
May I restate the obvious? If vengeance is God’s, then it is not ours. God has not asked us to settle the score or get even. Ever. Forgiveness is not saying the one who hurt you was right. Forgiveness is stating that God is fair and he will do what is right. After all, don’t we have enough things to do without trying to do God’s work too?
