I go further and say that there is a great need in the contemporary world for more Christian anger. We human beings compromise with sin in a way in which God never does. In the face of blatant evil we should be indignant not tolerant, angry, not apathetic. If God hates sin, His people should hate sin too. If evil arouses His anger, it should arouse ours too. What other reaction can wickedness be expected to provoke in those who love God?
