46 An argument arose among them as to which one of them was the greatest. 47 But Jesus, aware of their inner thoughts, took a little child and put it by his side, 48 and said to them, "Whoever welcomes this child in my name welcomes me, and whoever welcomes me welcomes the one who sent me; for the least among all of you is the greatest."
49 John answered, "Master, we saw someone casting out demons in your name, and we tried to stop him, because he does not follow with us." 50 But Jesus said to him, "Do not stop him; for whoever 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.
