Then children were brought to him that he might lay his hands on them and pray. The disciples rebuked the people, but Jesus said, “Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven.” And he laid his hands on them and went away. (Matthew 19:13-15)
In his book The Ragamuffin Gospel, Brennan Manning writes:
The kingdom belongs to people who aren’t trying to look good or impress anybody, even themselves. They are not plotting how they can call attention to themselves, worrying about how their actions will be interpreted or wondering if they will get gold stars for their behavior. Twenty centuries later, Jesus speaks pointedly to the preening ascetic trapped in the fatal narcissism of spiritual perfectionism, to those of us caught up in boasting about our victories in the vineyard, to those of us fretting and flapping about our human weaknesses and character defects. The child doesn’t have to struggle to get himself in a good position for having a relationship with God; he doesn’t have to craft ingenious ways of explaining his position to Jesus; he doesn’t have to create a pretty face for himself; he doesn’t have to achieve any state of spiritual feeling or intellectual understanding. All he has to do is happily accept the cookies, the gift of the kingdom.
