I take it that your answer is 'no'. You could have simply said so instead of putting up all this interference. So if Christ was not in them, how were they able to prophesy, cast out demons, and perform signs and wonders?
"Even him, whose coming is after the WORKING OF SATAN with ALL POWER AND SIGNS AND LYING WONDERS."(2 Thess.2:8,9).
Did they actually do those things or did they merely claim to have done them?
"Even him, whose coming is after the working of Satan with all power and signs and lying wonders" (2 Thess 2:9)
...how was this fellow able to perform signs and wonders?
Act 19:13 Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth.
Act 19:14 And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so.
Act 19:15 And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye?
2Co 11:14 And no marvel; for Satan himself is transformed into an angel of light.
2Co 11:15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
There's plenty of scripture to support it...Simon the sorcerer was proficient at performing miracles but he couldn't lay his hands on people and have them filled with the spirit...
