The Integrity Crisis by Warren W. Wiersbe, Thomas Nelson Publishers, 1991, pp. 75-76
What we need today is not anger, but anguish, the kind of anguish that Moses displayed when he broke the two tablets of the law and then climbed the mountain to intercede for his people, or that Jesus displayed when He cleansed the temple and then wept over the city. The difference between anger and anguish is a broken heart. It's easy to get angry, especially at somebody else's sins; but it's not easy to look at sin, our own included, and weep over it.
