Definitely worth pursuing. I think a bit more restraint in the verse, more breathe-y vocals. You've got a good chorus there, but I'm not hearing anything gospely, but I really like the staccato vocal delivery (the 'would you, would you...' bit). Its the delivery as much as the melody that creates the hook in this instance. I'm going to break ranks with the other suggestions and say keep it raw, veer away from wall of sound, gospel choirs etc! Church or hammond organ a good suggestion though.
