Gethsemane teaches us that the kingdom of God is entered only through the denial of one's own will and the affirmation of the will of God. Therefore, the cross must stand central to an understanding of the kingdom. Since the essence of the kingdom is our obedience to the absolute will of God, we understand it only as we bring our own will to the foot of the cross. No self-will can live unchallenged in God's kingdom.
