Do I believe that there are charlatans and scam artists that present themselves as "holy men of God" and screw people out of money and mess w/their minds? Yes.
But do I believe that God could raise anyone He wants from the dead in any way He chooses? Yes. Do I believe this guy in the first video (only one I watched) was used by God to raise the dead in 2 people? If he's looking for $ in regard to it, then I am going to have a hard time believing about anything he says.
AGree w/loco on the next "wave" of public signs and wonders:
Matt 24:23-24
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.
Rev 13:11-17
11 Then I saw a second beast, coming out of the earth. It had two horns like a lamb, but it spoke like a dragon. 12 It exercised all the authority of the first beast on its behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed. 13 And it performed great signs, even causing fire to come down from heaven to the earth in full view of the people. 14 Because of the signs it was given power to perform on behalf of the first beast, it deceived the inhabitants of the earth. It ordered them to set up an image in honor of the beast who was wounded by the sword and yet lived. 15 The second beast was given power to give breath to the image of the first beast, so that the image could speak and cause all who refused to worship the image to be killed. 16 It also forced all people, great and small, rich and poor, free and slave, to receive a mark on their right hands or on their foreheads, 17 so that they could not buy or sell unless they had the mark, which is the name of the beast or the number of its name.
