There are plenty of things to worry about and we can't fix everything. We need a healthy balance of concern and relinquishment of concern. What is within our control and what is not? In todays reading Paul shakes his clothes to symbolise his decision to stop trying to influence the Jews in Corinth. He had done all he could do and they were not his problem any more. Sometimes we need to do this too and just leave what is not within our circle of control.
