Abraham, Isaac, and Jacob always lived as strangers in their own land. That's actually a good thing. Assimilation into the local, Canaanite culture would have been a disaster. God wants us to be separate from the world, but separateness isn't the point. Service, justice, obedience, and the Gospel: these are the point.
