Mark 9:39
Do not stop him, Jesus said. For no one who does a miracle in my name can in the next moment say anything bad about me — the permissive response is unequivocal: do not stop him. The logic is theological: using Jesus' name to drive out demons is an implicit confession of Jesus' power and authority — someone who acknowledges that authority in practice cannot be an enemy in principle. The kingdom's work is not restricted to the authorized inner circle.
