The way you said this is interesting. “Jesus promise to return shortly in revelation” I get you were referring to the book? But how did Paul see Him? By Revelation?
either Jesus promise to return shortly in Revelation (Spirit?) was truth or it was a lie. —I don’t think it was a lie since Paul confirms that he was taught by the Revelation of Jesus Christ. Galatians 1:12 For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
What is Revelation if not a revealing or to reveal? Or to be made seen?
John wrote revelation to seven specifc churches of Jesus telling some of them to get rid of things that where hindering them or they would be cut off, there was a promise of destruction placed forth by Jesus to his apostles and this is the full scope of it all. And that Jesus was going to return shortly, quickly without delay, promised to come back the same way he ascended. Therefore I believe the faithful in the great tribulation seen the Son of Man, coming in the clouds as a reality which was promised.
