To generate imagery in the mind, of things which are not real in our spatio-temporal reference frame is a form of deception, IF we choose to think of it that way. That raises an interesting notion: when Jesus appeared to Saul on the road to Damascus, was Saul being deceived with an image that was not physically real, or was Saul given a special ability to see what his companions could not see as clearly ... the compn\anions apparently sense something but could not identify a coherent message in what they sensed.
That brings to mind what Moses experienced on the mountain, when God covered eyes as Moses stood in the cleft of the rocks as God passed by him. I believe that to be one of the 'Christophanies', but that's just simple me ... and a few dozen Biblical Scholars.
Interesting thought...
I certainly don't question Paul's nor any of that which they saw and experienced before Christ came and while here..and for that matter, what the Apostles saw and did. But that was another time then what we live ..for we have the Scriptures and His Spirit within us to guide and lead. God did some amazing things at that time though, and I take them as written.
I do think that many today seek these encounters because they ‘want to believe’ in UFO'S and a spiritual realm they desire access to and seek... So they're ‘already’ in a state of mind to be deceived....and the enemy of men's souls is happy to accommodate, as in the long run it will lead people away from the true reality which is in Christ and “experiencing” Him as he would have them do.
