I haven't written anything about the disasters in Japan yet. I still am trying to get my head around it. Having family there means that it's too personal to separate from.
I worry. I pray. I give. I took my family on campus last week for the benefit concert hosted by the Nikkei Student Union. We folded cranes, made donations, bought cool beadwork that says "I Love Japan." We were there. Sometimes that's all you can do.
Here is a link to an article by one of our United Methodist Bishops on the disaster. I hope his thoughts are helpful to you.
