The point is that we're here to make our moral choices ourselves. No one can sacrifice himself as a substitute for a person's genuine repentance, much less so that he doesn't even have to try to be good as Paul declared. The idea is Satanic, symbolically speaking of course. Paul was almost certainly the Beast of Revelation, the number of the beast (which isn't 666, Arabic numerals coming later) is Jewish Gematria for Tarsus. Let him who has wisdom understand. (Which I'm not claiming btw. I was put on to Gematria by some modern day Jewish followers of (a human) Jesus, Ebionites.
Yes, sorry, I gotta go where the evidence, or lack of it, leads me, and this just looks like a set up. You may be sincere, but I don't see an inkling of anything that would make me doubt the rock solid reality I've been witness to, and seen the evidence build up for, all my life. Why would God or the Holy Spirit or whatever seek out a minuscule chosen few and give you nothing but It's word as validation--in the face of this vast, exceedingly rational universe. If God was going to break It's silence and violate our free will, why not everywhere at once, in all the different languages, so no one could exploit that power? How do we know it's not a hallucination, or a (self-)deception? How do you know? Did you at least receive some proof, some verification? We're hearing this on the Internet after all, and look at all that unbroken string of false religions, with none of them having the first thing to show for themselves besides hearsay.
If you'd been told to sacrifice one of your children, or even your dog, would you have? I don't ask that question lightly This stuff is dangerous.
