Humility is not common in a sinful world, especially amongst adults who think that they are 'someone'.  As parents were pushing their children forwards for Jesus to commend them to His Father and bless them, the disciples were upset that He was paying them too much attention.  After all, children were not important, they thought.  So the men from Jesus' team decided to stop the flow of youngsters who were getting in the way of the 'real ministry' as they saw it.
 
Jesus disagreed. “Let the little children come to Me”, He said, repeating His teaching in Matthew 18:1-4.  Little children had nothing to contribute except a lot of excitement, and the peaceful pleasure that Jesus was welcoming them.  "Do not hinder them", was a rebuke - followed by His explanation.  His kingdom was not for self-important people, even if they had been helping Him ... it was for humble people who are willing to come to Jesus, without any conditions, and be open to receive His love.
 
The children were willing to come, and glad that their parents had encouraged them.  They had just the right attitude: they saw Jesus as a wonderfully kind person with 'something special' about Him and they wanted to be with Him.  They could not analyse Him but somehow felt that He knew all about them; and they were content with that.  Jesus said that such a heart attitude is essential if anybody is to enter His kingdom.  Indeed, without child-like humility it is impossible to enter His kingdom.  Both Mark and Luke record Jesus saying, “I tell you the truth, anyone who will not receive the kingdom of God like a little child, will never enter it” (Mark 10:15; Luke 18:17).
 
Arrogance and pride, in their many forms, always let their owners down.  The hollow reality behind the bravado and sanctimonious wisdom is so easily seen by Jesus.  He is not at all impressed by the 'spiritual' impression given by power-hungry people.  What He is looking for are honest people who bring nothing more than their weakness and faith in Him, eager to receive whatever He will give.  That idea mystifies many people who believe that God is pleased when they try hard.  However, simple faith is neither immature nor mentally defective; it is the essential qualification for being welcomed by Jesus.  Stop pretending how good you are, be real: repent of your pride and be grateful that Jesus wants to bless you.  It will be a pivotal moment in your relationship with Him.
