But how?

RE: But how?
The Bible tells us “by their fruits, ye shall know them”.
The existence of demonic miracles is one reason why we must test all spirits: “Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world” (1 John 4:1). Any time we are in doubt, we are to make sure that what is being taught lines up with what Scripture says.
If the miracle worker is teaching something contrary to God’s Word, then his miracles, no matter how convincing they seem, are a demonic delusion.
