Matt 24: 23-27
5 For many shall come in my name, saying, I am Christ; and shall deceive many. (Matt. 24: 5)
23 Then if any man shall say unto you, Lo, here is the Christ, or, Here; believe it not.
24 For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect.
25 Behold, I have told you beforehand.
26 If therefore they shall say unto you, Behold, he is in the wilderness; go not forth: Behold, he is in the inner chambers; believe it not.
27 For as the lightning cometh forth from the east, and is seen even unto the west; so shall be the coming of the Son of man.
Yeshua says not to listen to people who say they meet him in the desert. He says that when he returns everyone will see him.
You have another problem because Paul was the only one to validate his personal revelation. It takes 2 or 3 to make a witness valid and all we have is Paul's word.
Again you misunderstand.
When Christ would return in an invisible presence he would not come as a man on earth. Therefore Christians should not look for him in the wilderness, so that they could train with him in some out-of-the-way place for a revolution. Nor would he be in some secret inner chambers, where he could conspire against world governments with his followers. No, his presence was to be like lightning, not in its being instantaneous and unexpected, but in its being seen over a wide area, in the open, for everyone to behold. (Luke 17:24; compare Psalm 97:4.) His followers would not keep their knowledge of his invisible presence secret, but would give it widespread proclamation.Matt. 10:26, 27.
The chosen ones, Jesus said, would not be deceived and disappointed by false Christs. They are symbolically like eagles in having sharp spiritual insight. As an eagle knows where the carcass on which he is to feed is to be found, so the farsighted chosen ones would gather together to the looked-for Messiah, Jesus, to feed on the spiritual food at the right Messianic place, because they would discern the true Christ.Luke 17:37.

You also have to remember,those who followed Jesus Christ knew that the destruction of Jerusalem had to take place first.This happened in 70 C.E.
Jesus gave these warnings, which had an application, first, to Jerusalem with her people, and then to Christians during the centuries after Jerusalems destruction. Following this warning he used the expression immediately after the tribulation of those days. (Matt. 24:29) This expression constituted a division, timewise. What he said from this point on applied only in one sense, namely, in modern times, not to Jerusalem back there. How can this be properly said?

Another thing
You mentioned there would need to be 2 or 3 witnesses to confirm Paul's story.There were those men who saw the light when Paul was riding to Damascus.Ananias is also a witness.
