Mark 9:33-40

33Then they came to Capernaum. While Jesus was in the house, He asked them, “What were you discussing on the way?” 34But they were silent, for on the way they had been arguing about which of them was the greatest.

35Sitting down, Jesus called the Twelve and said, “If anyone wants to be first, he must be the last of all and the servant of all.”

36Then He had a little child stand among them. Taking the child in His arms, He said to them, 37“Whoever welcomes one of these little children in My name welcomes Me, and whoever welcomes Me welcomes not only Me, but the One who sent Me.”

38John said to Him, “Teacher, we saw someone else driving out demons in Your name, and we tried to stop him, because he does not accompany us.”

39“Do not stop him,” Jesus replied. “For no one who performs a miracle in My name can turn around and speak evil of Me. 40For whoever is not against us is for us.
