I’ll ask you the same thing I asked him...You say it’s true, can you prove either exist? Can you supply proof that would convince anyone, anywhere? Can the proof be repeated? Is it just a matter of what one believes?
I have an authoritative work from Someone Who knows.
You have your own “experience”.
Such a position begs the question. If one only beliefs such things if given absolute proof independent of faith, then such a thought is just as alien to what God provides as not having any notion about it in the first place.
Not to worry, though, every human will be exposed to such beings in due time. It's won't be an enjoyable experience for those who reject what God provides for salvation. Meanwhile, we are also warned no to allow others take our crowns from us.
