Ok so say I suddenly believe in God, now what?

You can say thoughts and prayers instead of just thoughts.

I have always wondered about teetotal religious people, perhaps when they arrive at the pearly gates St. Peter will say "if only you knew how much trouble God went to, to make malted barley and hops taste that good"

Wait patiently for Him to give you instructions.

I don't see a problem with those things.

are you part of a religion? If so, which one?

Can u dance to begin wit?

Depends on your contribution ☺

Then continue being an antagonistic atheist

You can drink beer, just drink it in moderation.
You can still party, just don't do anything stupid.
You can still dance, don't be silly.
