J. Oswald Sanders on Anger
“F. W. Robertson was similarly stirred by righteous anger on one occasion. Describing his reaction he said: ‘My blood was at the moment running fire, and I remembered that once in my life I had felt a terrible might; I knew and rejoiced to know that I was inflicting the sentence of a coward’s and a liar’s hell.’ Martin Luther claimed that he ‘never did anything well until his wrath was excited, and then he could do anything well.’”
