Come out from among them, and be ye separate. 2 Corinthians 6:17.
With all the world in his choice, God placed His ancient people in a very remarkable situation. On the north they were walled in by the snowy ranges of Lebanon; a barren desert formed their eastern boundary; far to the south stretched a sterile region, called the howling wilderness; while the sea—not then, as now, the highway of the nations, facilitating rather than impeding intercourse—lay on their west, breaking on a shore that had few harbors and no navigable rivers to invite the steps of commerce.
May we not find a great truth in the very position in which God placed His chosen people? It certainly teaches us that to be holy, or sanctified, we must be a separate people—living in the world, but not of it—as oil, that may be mixed, but cannot be combined with water.—Guthrie.
