After Jesus had finished teaching the
disciples, John said to him,
"Teacher, we saw someone
casting out demons in your name,
and we tried to stop him,
because he was not following us."
But Jesus said,
"Do not stop him;
for no one who does a deed of power
in my name will be able
soon afterward to speak evil of me.
Whoever is not against us is for us."
