Once, Jesus’ disciples–who were beginning to realize that God’s kingdom was not like earthly kingdoms–asked him to clarify: Who is the greatest in the kingdom of heaven? In other words, how do you move ahead? By way of reply, Jesus “called a little child, whom he placed among them. And he said: ‘Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. Therefore, whoever takes a humble place–becoming like this child–is the greatest in the kingdom of heaven'” (Matt. 18:2-4, NRSV).
