Fixation With Forgiveness?

I know a minister who suffered deep injustice in his ministry, and his greatest influence ended through injustice. He dealt with it by proclaiming that he had forgiven everyone. Yes, he said, he had forgiven everyone. Ten years later, he had forgiven everyone. Twenty years later, thirty years later, he preached about it, wrote about it, and advised everyone else to do the same always. Then suddenly he walked into one of his past Churches – not the one which had done him the injustice – and read them the riot act. People were stunned, baffled, confused. Someone said to me, perhaps it was still sitting with him all along? OBSERVATION: If so, what of such ministers in general, who forgive?
