The Kingdom is built upon weakness. Strength is anti-kingdom.
Steve DeNeff was here last week, and he said this: "God divests himself into his people, so he is only as power as his people." This is very interesting as God is all powerful, there's nothing that he cannot do, but he chooses to limit himself. When Jesus was born, he was God, but yet he was defenseless as he trusted his well being to Joseph and Mary. Think about it, if Joseph hadn't left Bethlehem when he did, Jesus would have been killed by Herod. We do not see God just appearing and everybody falling down, instead he comes as a baby.
Possibly my favorite quote of all time is this: "The weakness of the Christ's cross is the ultimate criticism of all our attempts at power and security." What it is saying is that Jesus' salvific act was one that is trying to get us to see how dangerous our attempts at power and control are deadly! His act is not just about atonement, but it is also the way that the kingdom works. (Remember the cross was the sign of failure and the sign of being dominated a stronger nation.)
Thus, when we play power games we are not being like God or Jesus. They - even though all the power in the world was in their grasp - acted from positions of weakness!
