DHK, show us your exposition of this chapter.
Gladly:
At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven? (Matthew 18:1)
--The topic: Who is the greatest in the kingdom?
And Jesus called a little child unto him, and set him in the midst of them, (Matthew 18:2)
--A child is used as an illustration, an object lesson.
And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. (Matthew 18:3)
--The child itself is not converted. The child has faith. His faith in his parents, and at this moment in Christ who holds him. He is a trusting child. The topic here is trust, faith, without which you cannot please God. Without faith in Christ you cannot enter into His Kingdom. That is the illustration.
Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. (Matthew 18:4)
--The child in humility and faith came to Jesus. Servanthood and humility are the key to greatness in the kingdom. Notice the simile--"as this little child." He is not talking about children.
And whoso shall receive one such little child in my name receiveth me. (Matthew 18:5)
--This is a metaphor. The child is now the believer.
But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea. (Matthew 18:6)
--This is also a metaphor, but better defined. Notice the children, "
which believe in me". It is evident here that the children are believers in Christ. They have believed in Christ. Thus in verse 5 if we receive a believer in Christ's name, we also are receiving Christ. That doesn't apply to an actual "child." It applies only to believers.
But to those who offend believers (cause to stumble), it would be better for him to be dead. Christ is speaking of the severity of judgment that will come on those who cause believers, especially new believers to stumble, to fall, etc. Judgement will fall on those that persecute Christians. Perhaps not in this day, but that day will come.
His words only become stronger:
Woe unto the world because of offences! for it must needs be that offences come; but woe to that man by whom the offence cometh! (Matthew 18:7)
He is speaking against those who cause Christians to stumble and fall.
