"It's Tuesday and I still don't know what hymns we're going to sing on Sunday! I don't even have the text or sermon topic. How am I supposed to choose organ music that will integrate with the service"?"
Just then the phone rings. It's the pastor, and he's chosen his text. He's selected some hymns too, although he's still not sure which stanzas to sing.
"Oh well, at least I can choose the prelude, postlude, and offertory. I'll work on the hymns later—after he decides about the stanzas."
