Luke 9:46-50

46An argument started among them as to which of them might be the greatest [surpassing the others in esteem and authority].

47But Jesus, knowing what they were thinking in their heart, took a child and had him stand beside Him,

48and He told them, “Whoever welcomes this child in My name welcomes Me; and whoever welcomes Me [also] welcomes Him who sent Me; for the one who is least among all of you [that is, the one who is genuinely humble—the one with a realistic self-view]—he is the one who is [truly] great.”

49John replied, “Master, we saw someone driving out demons in Your name; and we tried to stop him because he does not follow along with us.”

50But Jesus told him, “Do not stop him; for he who is not against you is for you.”
