The Walls We Build ... and the ones God takes down

One day at the Medair retreat we did a little exercise in which we built a dividing wall. See the photo for what the wall looked like.
       I had everyone do a powerful little exercise in which I had them divide based on a series of questions:
* Men on one side, women on the other
* Those who have voted in an election, those who have NOT;
* Those from cultures which were colonized, those from cultures who were imperial;
* Those from cultures who were victims of genocide, those from cultures who perpetrated them.
       And so it went, as we experienced first-hand the LACK of shalom we all experience because of the walls we build between peoples and cultures.
       Then we read these astonishing words from the apostle Paul regarding Jew and Gentile:

For [Christ] himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, and in one body to reconcile both of them to God through the cross, by which he put to death their hostility. He came and preached peace to you who were far away and peace to those who were near. For through him we both have access to the Father by one Spirit. (Ephesians 2:14-18)
