And they were bringing children to him that he might touch them, and the disciples rebuked them. But when Jesus saw it, he was indignant and said to them, “Let the children come to me; do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.” And he took them in his arms and blessed them, laying his hands on them.
The term "childlike faith" comes from this passage. When I consider it my mind flashes back to the way that my children trusted me when they were very young. Before they were influenced by their friends, their teachers and TV shows they had a simple faith in the things that I taught them. Such is the way that our heavenly Father wants us to come to him.
Unfortunately for many God's kingdom has become less about trusting him like a child and more about understanding him as an adult. To such an end we develop all sorts of intellectual theologies and heady ways to explain things that aren't meant to be explainable. It is like we have rejected the wonder of childlike faith for something less miraculous.
Help me Lord to never to forget that you are my heavenly Father and that I am your child.
