Even though I have my criticism of Christianity and its adherents, I would say Christianity when done right, is the best, most impressive religion. I have witnessed miracles, the supernatural, in Jesus' Name. So, we can argue all day about the historicity of the events described in the gospels and in the Bible in general (OT-NT), but when it comes down to it, irrespective of the historicity of events, there's something there that is real and powerful. Maybe it's the way that Christian beliefs affect human consciousness, "triggering" miracles, as if the universe approves of the beliefs, even if it's not historical in a literal sense. Christ might be a cosmic "archetype" symbolizing self-sacrifice and love.
We still don't fully grasp the nature of human consciousness and how the universe works. It's pretty much a mystery that we're researching and trying to unravel. Maybe a mind "possessed" or maybe I should say occupied, by a certain set of values and sentiments, "faith", can alter the physical world, with their minds. Christians who have suspended their disbelief or rational mind and are operating in a meta-rational state of thinking, a supra-rational form of thought that is in a higher dimension, allowing that person to function at a "higher frequency" of alignment with higher beings ("angelic beings"). Maybe that's how a true, genuine disciple of Jesus can perform miracles.
I believe most so-called "Christians", aren't truly Christians, they're charlatans and jokers, trying to trick God into saving them, because they refuse to die. To carry their crosses and follow Christ to Golgotha, the place of the skull, outside the walls of the city. Life in Christ requires the death of the disciple. The true born again (born from above) believer, is someone who is fully committed to The Way, of the straight and narrow, carrying their cross daily and dying, loving their brothers and sisters as Christ loved them. Such people are rare. What we have are "fad Christians", the greasy-grace "sinner's prayer", mega-church "Christianity", that Jesus will reject.
Mat 7:21-23 Not everyone that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. (22) Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? (23) And then will I profess unto them, I never knew you: depart from me, ye that work iniquity (GRK-ANOMIA-LAWLESSNESS).
