I grew up in and around churches. It's funny about music. Our choir always had a grad student for a director because it was a university town and there were an endless supply of young people getting their masters or PHD who needed a choir for their final project. It improved the quality of sound during service enormously. There may be more than one young undeclared atheist in you church who appreciates the sound of your organ just for the quality.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
