Mark ch 13 21And then if anyone tells you, Look, here is the Messiah, or, there he is, dont pay any attention. 22For false messiahs and false prophets will rise up and perform miraculous signs and wonders so as to deceive, if possible, even Gods chosen ones. 23Watch out! I have warned you!
So far no names just an internet account. I believe in miracles but I believe in reasonable caution and verification as well. Christ after healing told ones to show themselves to the Priest.
One fairly well known account I have heard of was a preacher who was killed in a car wreck and a fellow preacher who saw the aftermath of the wreck knew him & prayed over him for about 90 minutes after he was pronounced dead. He was pronounced dead, documented as such by professionals, and through a miracle from GOD came back. I believe he wrote a book called 90 minutes in heaven.
I also try to find out about the source, whether they have sound doctrines such as believing in The Trinity etc. for devils are able to produce false "miracles" that are ultimately no more than just tricks and the false fruits of emotionalism used to promote lies and entrap the simpleton.
