Natural Selection Seems Insufficient

[Jal]

You should believe Religion-X only if you find it impossible to disbelieve Religion-X. 

Clear?   I mean, how else could it work?  What other approach might God take? None, right?

Therefore when God is ready to help someone convert, He must take it upon Himself to impose an invincible persuasion. 

Evangelicals call it, "The Inward Witness of the Holy Spirit"  (I thought you and I discussed this already?).

That doesn't make it a tautology.  It's only an invincible persuasion if God exists and provided such.  If God doesn't exist, it's just a false belief.

This is just you using words incorrectly again.

 Nope. Whether God exists is irrelevant to my point.  Unlike blind faith, a belief is justifiable/ warranted if you cannot relinquish it. 

In fact that is virtually the ONLY scenario where a belief is fully justified.
