Luke 9:46-50

46 Then there arose a reasoning among them, which of them should be greatest.

47 And Jesus perceiving the thought of their heart, took a child, and set him by him,

48 And said to them, Whoever shall receive this child in my name, receiveth me; and whoever shall receive me, receiveth him that sent me: for he that is least among you all, the same shall be great.

49 And John answered and said, Master, we saw one casting out demons in thy name; and we forbad him, because he followeth not with us.

50 And Jesus said to him, Forbid [him] not: for he that is not against us, is for us.
