John said to him, “Teacher, we saw a man who was driving out demons in your name, and we told him to stop, because he doesn't belong to our group.”
Believers will be given the power to perform miracles: they will drive out demons in my name; they will speak in strange tongues;
“Do not try to stop him,” Jesus told them, “because no one who performs a miracle in my name will be able soon afterward to say evil things about me.
If this is how I drive them out, how do your followers drive them out? Your own followers prove that you are wrong!
