Luke 9:46-48 NIV

[46] An argument started among the disciples as to which of them would be the greatest. [47] Jesus, knowing their thoughts, took a little child and had him stand beside him. [48] Then he said to them, “Whoever welcomes this little child in my name welcomes me; and whoever welcomes me welcomes the one who sent me. For it is the one who is least among you all who is the greatest.”
