18. These words of Jesus should be understood as referring to the wrath which His doctrine will provoke, the momentary conflicts which it will create and to the fights it will have to endure before it is established, just as happened to the Hebrews before they entered into the Promised Land. It should not be understood as inferring a predetermined design on His part to sow disorder and conflict. Evil comes from Man, never from Jesus. He was like the doctor who comes to cure, but whose medicine provokes a beneficial crisis in those who are sick.
