To Become Mature, We Must Become Like Children: The Upside-Down Way of Spiritual Growth
The child’s littleness, immaturity and need of assistance, though commonly disparaged, keep the way open for the fatherly love of God, whereas grown-ups so often block it.
In first-century thought children were often very little esteemed. Jesus ascribes to them great value, but here his more immediate point is that would-be disciples must share their condition of utter dependence, in this case, on God. Without a recognition of one’s fundamental inability to save oneself and without a subsequent complete reliance on God’s mercy, no one can enter the kingdom of heaven. Conversely, those who most clearly perceive their helplessness and who respond accordingly are the greatest in the kingdom (again the “is” refers to the present aspect of the kingdom).32
The kingdom upturns secular values. Real greatness is not to be found in seeking to be praised and served by others, but in seeking others to serve, especially those who have no rights.
In the previous two chapters, we’ve seen Peter’s confession of Jesus as the Christ (16:16) as well as Jesus’ transfiguration before Peter, James, and John on the mountain (17:1–2). These significant events seem to be at least a part of the reason for the disciples’ question to Jesus in verse 1: “Who is greatest in the kingdom of heaven?” Perhaps some thought that the greatest was Peter, the disciple who was singled out by Jesus in the institution of the church (16:18) and who was also permitted to see Jesus’ glory on the mountain.
