Luke 9:46-50

An argument started among the disciples as to which of them would be the greatest. Jesus, knowing their thoughts, brought a little child to his side and said to them, "Whoever welcomes a little child like this in my Name, also welcomes me; and whoever welcomes me also welcomes the One who sent me. For whoever is least among you - will be great." John responded by saying, "Master, we saw someone casting out demons in your Name, and we tried to stop him, because he is not one of us." But Jesus said, "Do not forbid him, for anyone who is not against us, is for us."
