I don't think I would call it a miracle, but I also believe I was guided by holy spirit when I was mysteriously bounced from a die hard KJV site to one about universal reconciliation. I first thought it was just a strange coincidence as I've been told about when I was compelled to look in the drawer beside a hospital bed and found nothing but a Gideon Bible. I think mystical experiences happen to lots of folks in various ways, and those who are spiritually discerning eventually recognize what's up. I think the miracles Jesus performed were in a different class though because they were obvious visual phenomena that were mind blowing to all who saw them, and I think they were meant to show the power of God. So the folks who claimed they were being performed by the power of the chief of demons weren't just doubting Jesus. They were insulting God. That's why it was called an unpardonable sin, but even the folks guilty of that will eventually be reconciled with God at the consummation of the eons. I think folks now who are deceived by church doctrine about torture in fire forever are simply misinformed, but may even be believers in God. Since Christ was sacrificed for the sins of the whole world, I think we are in the time when God is conciliated with mankind, and mankind needs to be conciliated with God. I don't think what you read in Matthew 12:31 applies to folks today because justification, not pardon, is what we have now. A pardon can be withdrawn, but there is no condemnation in Christ. So I think, even though believers may be misled by some false doctrine, those believers who have been taught torture in fire forever are saved.
