Like Lightning

According to a recent story in Newsweek magazine, a contemporary TV personality has built up quite a following by claiming to be the second coming of Jesus Christ:

"In the rapturous eyes of his flock, Jose Luis de Jesus Miranda is, in fact, the second coming of Christ. As the head of the Growing in Grace International Ministry, he presides over a sprawling organization that includes more than 300 congregations in two dozen countries, from Argentina to Australia. He counts more than 100,000 followers and claims to reach millions more through a 24-hour TV channel, a radio show and several Web sites." ('He Calls Himself God,' by Arian Campo-Flores, Newsweek, Feb. 5, 2007)

Is there any need, Biblically, to investigate this man's claims?:

“Then if anyone says to you, ‘Look, here is the Christ!’ or ‘There!’ do not believe it. For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect. See, I have told you beforehand.
“Therefore if they say to you, ‘Look, He is in the desert!’ do not go out; or ‘Look, He is in the inner rooms!’ do not believe it. For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be.”
(Matthew 24:23-27).

In other words, if you have to ask, it's not Him.
