The Messiah has made things up between us so that we're now together on this, both non-Jewish outsiders and Jewish insiders. He tore down the wall we used to keep each other at a distance.
He repealed the law code that had become so clogged with fine print and footnotes that it hindered more than it helped. Then he started over. Instead of continuing with two groups of people separated by centuries of animosity and suspicion, he created a new kind of human being, a fresh start for everybody.
Christ brought us together through his death on the Cross. The Cross got us to embrace, and that was the end of the hostility.
Christ came and preached peace to you outsiders and peace to us insiders.
He treated us as equals, and so made us equals. Through him we both share the same Spirit and have equal access to the Father.
