30 They went on from there and passed through Galilee. And he did not want anyone to know, 31 for he was teaching his disciples, saying to them, "The Son of Man is going to be delivered into the hands of men, and they will kill him. And when he is killed, after three days he will rise." 32 But they did not understand the saying, and were afraid to ask him.
33 And they came to Capernaum. And when he was in the house he asked them, "What were you discussing on the way?" 34 But they kept silent, for on the way they had argued with one another about who was the greatest. 35 And he sat down and called the twelve. And he said to them, "If anyone would be first, he must be last of all and servant of all." 36 And he took a child and put him in the midst of them, and taking him in his arms, he said to them, 37 "Whoever receives one such child in my name receives me, and whoever receives me, receives not me but him who sent me."

Commentary on Mark 9:30-40
(Read Mark 9:30-40)
The time of Christ's suffering drew nigh. Had he been delivered into the hands of devils, and they had done this, it had not been so strange; but that men should thus shamefully treat the Son of man, who came to redeem and save them, is wonderful. Still observe that when Christ spake of his death, he always spake of his resurrection, which took the reproach of it from himself, and should have taken the grief of it from his disciples. Many remain ignorant because they are ashamed to inquire. Alas! that while the Saviour teaches so plainly the things which belong to his love and grace, men are so blinded that they understand not his sayings. We shall be called to account about our discourses, and to account for our disputes, especially about being greater than others. Those who are most humble and self-denying, most resemble Christ, and shall be most tenderly owned by him. This Jesus taught them by a sign; whoever shall receive one like this child, receives me. Many have been like the disciples, ready to silence men who have success in preaching to sinners repentance in Christ's name, because they follow not with them. Our Lord blamed the apostles, reminding them that he who wrought miracles in his name would not be likely to hurt his cause. If sinners are brought to repent, to believe in the Saviour, and to live sober, righteous, and godly lives, we then see that the Lord works by the preacher.
