Luke 9:46-49

An argument started among them as to which of them might be the greatest [surpassing the others in esteem and authority]. [Matt 18:1-5; Mark 9:33-37] But Jesus, knowing what they were thinking in their heart, took a child and had him stand beside Him, and 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.” John 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.” [Mark 9:38-40]
