What I mean is that for some people, the Gospel toggle some previously unknown bits in the brain that activates and transforms them. And, worship just becomes what they do. It's the freedom of it - they become unshackled. I really don't know how to describe it in a way that my previous atheist self would understand.
How about "shackled" instead of "unshackled"? That might make the thing you're describing seem less extraordinary.

Slave. That's what you describe.
I'm not attacking you when I say this: drugs can get you there, too.
