Jesus knew what thoughts were going through their minds, and he took a little child whom he set by his side and then he said to them, ‘Anyone who welcomes this little child in my name welcomes me; and anyone who welcomes me, welcomes the one who sent me. The least among you all is the one who is the greatest.’ John spoke up. ‘Master,’ he said, ‘we saw someone driving out devils in your name, and because he is not with us we tried to stop him.’ But Jesus said to him, ‘You must not stop him: anyone who is not against you is for you.’
