I highly recommend God's Stories, by Fred Anderson, as one of the very best preaching resources I've come across in a long time.
This past Sunday I used one of the stories as a spoken call to worship, and had the attention of the entire congregation. They could relate to where the story took place, and they learned history as well as an appreciation for freedom of worship from that one story. God's Stories is a great resource.
