In Acts 8:9-24 there was a witch named Simon who gained followers because of the signs and wonders he performed using his sorcery.
Today there are people (even in the church) who do the same thing under the pretense of “spiritual gifts.”
Jesus warned in Matthew 24:24: For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect.
We need to be careful that we don’t trust in someone just because of the gifts they have or miracles we see. We should first ask the Holy Spirit to reveal that person’s true nature to us.
Exodus 8:6-7 NIV
So Aaron stretched out his hand over the waters of Egypt, and the frogs came up and covered the land. But the magicians did the same things by their secret arts; they also made frogs come up on the land of Egypt.
