It would be a tie between the agnostic and the Mormon bishop because of the following teaching by Spencer W. Kimball (former LDS president):
Pray as if everything depended on the Lord, then work as if everything depended on you.
But you remind me of a great joke I heard once (told from the Mormon perspective, you may change the punch line to suit your religion of preference without ruining the joke.)
Billy Graham, Pope John Paull II, and Gordon B. Hinckley were sitting together fishing in a boat. They were getting hungry, so the Pope offered to get some sandwiches from the small store on the shore some hundred yards distant.
The Pope jumps out of the boat, dashes across the top of the water, buys the sandwiches, and comes walking back across the water and into the boat.
After eating the sandwiches, they get thirsty, so President Hinckley offers to grab some sodas. He hops out of the boat, trots across the surface of the water to the store, gets the sodas and walks back across the water into the boat.
A short time after that, they run out of bait. Wanting to take his turn to help, Billy Graham offers to buy some bait.
He hops out of the boat, whereupon he immediately sinks below the water.
The Pope turns to President Hinckley and says: Do you think we should have told him about the sand bar?
President Hinckley responds: What sand bar?
That's like the joke I heard years ago.
The Pope's assistant answers the phone one day, goes completely white and runs to the Pope.
"I have good news and bad news", he reports
The Pope says "Well, give me the good news."
The assistant says "God is on the telephone and wants to talk to you."
The Pope jumps up and says "That's great news! But what is the bad news?"
The assistant bows his head and starts studying his feet..."He is calling from Salt Lake."
