Unless you change and become like children, you will not enter the kingdom heaven. (Matt. 18:3)
Jesus spoke these words as a response to a question from his disciples. Which of us, they demanded to know, was the greatest in the kingdom of heaven. Jesus must have been struck by the contrast between his rivalrous disciples, so-called friends bickering and vying for attention, and the children who were playing nearby. He could have said, “I am, you silly gooses! Don’t compete with me – follow me!” But he had tried words before to no avail. So he summoned the children to show that greatness in the kingdom means playing joyfully in the moment with a humility that is heedless of rank or position. Only such as these, he explained, are able to know me and follow me.
