“Grow up!” “Don’t be such a child!” “Act like an adult!” These are all familiar messages that we start to hear as we get older. We are encouraged to leave behind the things of childhood and enter “the real world.” And there is a truth in this way of thinking. But the Lord also says almost the opposite: “unless you are converted and become as little children, you will by no means enter the kingdom of heaven” (Matthew 18:3). Although we do leave childhood behind, there is some spiritual element of childhood that it is essential for us to hold onto.
