New International Version - UK
Whoever is not against us is for us
38 ‘Teacher,’ said John, ‘we saw someone driving out demons in your name and we told him to stop, because he was not one of us.’
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, 40 for whoever is not against us is for us. 41 Truly I tell you, anyone who gives you a cup of water in my name because you belong to the Messiah will certainly not lose their reward.
Causing to stumble
42 ‘If anyone causes one of these little ones – those who believe in me – to stumble, it would be better for them if a large millstone were hung round their neck and they were thrown into the sea. 43 If your hand causes you to stumble, cut it off. It is better for you to enter life maimed than with two hands to go into hell, where the fire never goes out.
‘“the worms that eat them do not die,
and the fire is not quenched.”[c]
