Bob Sorge gives excellent advise and his book is a joy to read. It has a good list of places to go for P&W music etc. He covers worship from a Biblical prospective. It was a book that will be one of my chief resources for our Music Department.
Our dance ministry is using this book for a Bible Study and from the little I have read it is going to be an eye opener for us all. Worship goes beyond just lifting the hands and opening your mouth. Worship is a behavior and posture for all believers. I cannot wait until we really get into the study.
