Jesus actually told us not to believe anyone who claims to have seen Him.
For they are all false messiahs and false prophets.
Here are the verses in Matthew Chapter 24:
23 At that time if anyone says to you, ‘Look, here is the Messiah!’ or, ‘There he is!’ do not believe it. 24 For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect. 25 See, I have told you ahead of time.
26 “So if anyone tells you, ‘There he is, out in the wilderness,’ do not go out; or, ‘Here he is, in the inner rooms,’ do not believe it. 27 For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. 28 Wherever there is a carcass, there the vultures will gather.
Because when the genuine appearance of Jesus takes place, it won't be just 1 or 2 or 5 or 10 or even a thousand people will see it but everyone will see it, all the billions of people around the world will see it.
Lots of Christians are falling for the false appearances because of ignorance of scriptures.... Don't!
