46 And an argument arose among them as to which of them was the greatest. 47 But when Jesus perceived the thought of their hearts, he took a child and put him by his side, 48 and said to them, "Whoever receives this child in my name receives me, and whoever receives me receives him who sent me; for he who is least among you all is the one who is great."
49 John answered, "Master, we saw a man casting out demons in your name, and we forbade him, because he does not follow with us." 50 But Jesus said to him, "Do not forbid him; for he that 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.
