"Jesus perceived the thought of their hearts"

Scripture: Luke 9:46-50

The appetite for glory and greatness seems to be inbred in us. Who doesn't cherish the ambition to be "somebody" whom others admire rather than a "nobody"? Even the psalms speak about the glory God has destined for us. "You have made them a little lower than God, and crowned them with glory and honor" (Psalm 8:5). Jesus made a dramatic gesture by placing a child next to himself to show his disciples who really is the greatest in the kingdom of God.
What is the significance of Jesus' gesture? Jesus elevated a little child in the presence of his disciples by placing the child in a privileged position of honor at his right side. It is customary, even today, to seat the guest of honor at the right side of the host. Who is the greatest in God's kingdom? The one who is humble and lowly of heart — who instead of asserting their rights willingly empty themselves of pride and self-seeking glory by taking the lowly position of a servant or child.
Jesus, himself, is our model. He came not to be served, but to serve (Matthew 20:28). Paul the Apostles states that Jesus "emptied himself and took the form of a servant" (Phil. 2:7).
