Jesus made it clear that he wants us to believe in him like children. In other words, before we can become the children of God, we must first be like little children. A child has a simple soul. The younger ones are especially innocent. They believe in whatever they're told easily. Unlike adults, they don't plot or scheme with selfish motives in mind. Unlike adults, their minds are not cluttered with complicated analyses or plans. We grownups can all recall our carefree childhood days when we just ate, went to school, and played, not worrying about what all the adults had to worry about. When Jesus renews us, we are actually transformed into such new childlike creatures, living the carefree days again.
