The Israelites traveled through the desert for 40 years, with God providing constant guidance and constant sanctuary.  My father was a Marine in the Pacific in World War II.  He emerged from that war, where he killed many Japanese soldiers, refusing to be corrupted morally or ethnically by the experience.  He then welcomed with joy the news that his daughter would serve as an exchange student in Japan a couple of decades later.  We treat all people as our friends - and make sure that all enemies become friends of ours.  That is what living in God's sanctuary does for us.
