Mark 9:33-41

They arrived at Capernaum; and when He was in the house, He asked them, “What were you discussing and arguing about on the road?” [Matt 18:1-5; Luke 9:46-48] But they kept quiet, because on the road they had discussed and debated with one another which one [of them] was the greatest. Sitting down [to teach], He called the twelve [disciples] and said to them, “If anyone wants to be first, he must be last of all [in importance] and a servant of all.” Taking a child, He set him before them; and taking him in His arms, He said to them, “Whoever receives and welcomes one child such as this in My name receives Me; and whoever receives Me receives not [only] Me, but Him who sent Me.” [Matt 10:40; Luke 10:16; John 13:20] John said to Him, “Teacher, we saw someone casting out demons in Your name, and we tried to stop him because he was not accompanying us [as Your disciple].” [Luke 9:49, 50] But Jesus said, “Do not stop him; for there is no one who will perform a miracle in My name, and be able soon afterward to speak evil of Me. For he who is not against us is for us. [Num 11:27-29] For whoever gives you a cup of water to drink because of your name as followers of Christ, I assure you and most solemnly say to you, he will not lose his reward.
