So let's say all the verses are wrong and God tortures nonbelievers forever. What do you suppose will happen to a guy like me who mistakenly believed, and shared the belief, that God is loving and merciful and finds a way to save all men? Is God going to put me testicle in a nut cracker and crush them 60 times a minute forever and ever?
He certainly will not! We are saved by Grace through faith, not by doctrinal knowledge!
You can get all the doctrines wrong, but if you get Christ right, Brother, you belong to Him.
So what? You believed a false doctrine, but by the Grace of God, you no longer do!
It's the "false" in any doctrine that pushes man to take the "false" into reason and effect the truth of other things.
That's what's happening in the OP!
