If we are all connected

What does it mean, "There but for the grace of God go I?"
Jesus said in Matthew 25 v 40 "...Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me."

Perhaps this is related to our connection to each other. For what I do to the least of my brethren I do to myself. "Do unto others as you would have done unto you"; "love your neighbour as you love yourself..."- the opposite of Sartre's comment that "hell is other people" ("L'enfer, c'est les autres") This "us" vs "them" mindset enables the atrocities of war. We often have vicious attack thoughts directed at our siblings, and often a reminder of our connectedness triggers us to change our perspective. The offense has not gone away, but we may become more tolerant or understanding. Nothing changes but our own awareness of the connection. What about my connection to my neighbour? What about my connection to the worst offenders at the most maximum security prison? How do my feelings towards one of them change if I discover it's my high school chum, or my brother, or my mother? What if I realize that it's me? For somewhere, someone is in that prison realizing, "it's me. How could I have done such a thing?" If I suddenly realize it's my mother in that prison, what do I say to maintain my "us" vs "them" ideology? Do I still think we should "just hang them all"?

We are connected. We are ALL connected. The pierced foul mouthed rocker is not just the same age as my son. He IS my son. He is ME. So NOW what do I want to tell him?
