Now, that suggests to us that Christian people are out of their places, even in the eyes of worldly people, when they are fighting shoulder to shoulder with them in certain causes; and it suggests the propriety of keeping apart. 'Come ye out from among them, and be ye separate, saith the Lord' 'What do these Hebrews here?' is a question that Philistia often asks. But now turn to the other question. Elijah had fallen into the mood of depression which so often follows great nervous tension. He had just offered the sacrifice on Carmel, and brought all Israel back to the Lord, and Jezebel had flamed out and threatened his life. The usually undaunted prophet, in the reaction after his great effort, was fearful for his life and deserted his work, flung himself into solitude and shook the dust off his feet against Israel. Was that not just doing what I have been saying that Christian people ought to do--separating himself from the world? In a sense, yes, but the voice came, 'What dost thou here, Elijah?' 'Go back to your work; to Ahab, to Jezebel. Go back to death if need be. Do not shirk your duty on the pretence of separating yourself from the world.' So we put the two questions together. They limit one another, and they suggest the _via media,_ the course between, and lead me to say one or two plain things about that duty of Christian separation from an evil world. I. The first thing that I would suggest to you is the inevitable intermingling, which is the law of God, and therefore can never be broken with impunity.
