43 And they were full of wonder at the great power of God. But while they were all wondering at all the things which he did, he said to his disciples,
44 Let these words go deep into your ears, for the Son of man will be given up into the hands of men. 45 But this saying was not clear to them and its sense was kept secret from them so that they were not able to see it: and they had fear of questioning him about it.
46 Now there was a discussion among them about which of them would be the greatest. 47 But when Jesus saw the reasoning of their hearts, he took a small child and put him by his side, 48 And said to them, Whoever gives honour to this child in my name, gives honour to me: and whoever gives honour to me, gives honour to him who sent me: for whoever is least among you all, that man is great.
49 And John, answering, said, Master, we saw a man driving out evil spirits in your name, and we did not let him do it, because he was not one of us. 50 But Jesus said to him, Let him do it, for he who is not against you is for you.

Commentary on Luke 9:43-50
(Read Luke 9:43-50)
This prediction of Christ's sufferings was plain enough, but the disciples would not understand it, because it agreed not with their notions. A little child is the emblem by which Christ teaches us simplicity and humility. What greater honour can any man attain to in this world, than to be received by men as a messenger of God and Christ; and to have God and Christ own themselves received and welcomed in him! If ever any society of Christians in this world, had reason to silence those not of their own communion, the twelve disciples at this time had; yet Christ warned them not to do the like again. Those may be found faithful followers of Christ, and may be accepted of him, who do not follow with us.
