46 Then his disciples began arguing about which of them was the greatest. 47 But Jesus knew their thoughts, so he brought a little child to his side. 48 Then he said to them, "Anyone who welcomes a little child like this on my behalf welcomes me, and anyone who welcomes me also welcomes my Father who sent me. Whoever is the least among you is the greatest."
49 John said to Jesus, "Master, we saw someone using your name to cast out demons, but we told him to stop because he isn't in our group." 50 But Jesus said, "Don't stop him! Anyone 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.
