The context of the following conversation is Jesse was fasting so they could focus on God. They ran on empty.:
Jesse says I will starve myself for our lord, our God..
The friend responds That's a bit extreme, don't you think Jesse?..
Jesse responds I am hungry, but this pain doesn't even compare to the reward..
The friend responds I'm actually an atheist, I don't know what you're talking about..
Jesse responds You just wouldn't understand. Focusing on God is the greatest act a human could perform..
The friend responds You've lost me..
