Then John said, “Teacher, we saw a man using your name to force demons out of someone. He is not one of us. So we told him to stop, because he does not belong to our group.”
But if I use Satan’s power to force out demons, then what power do your people use when they force out demons? So your own people will prove that you are wrong.
And the people who believe will be able to do these things as proof: They will use my name to force demons out of people. They will speak in languages they never learned.
