What to make of this religious bumper sticker?

A white Ford F-150 with a tool box in the bed and ladders on the side pulls in front of me at the light. I notice a bumper sticker that says, "My Boss is a Jewish Carpenter" and another one with a number to call to report bad driving. The light turns green and I switch lanes and pull up next to the truck. On the doors is painted, "Fishbein Construction".
