If you take seriously that the first are last and the last are first, Christ as servant is not a deep, mystical idea to meditate on, but one that is incredibly foreign to the present age, to the powers and principalities of this world - this includes not just those who naturally capitulate to those powers and principalites, but also much of the Church. Jesus doesn't wash the disciples feet to simply show love, but to show the way things are supposed to be, that the meek, the poor, the lowliest are the inheritors of the Kingdom and are victors with God. This isn't rhetoric but reality: God in Christ lived it perfectly and is now King of kings.
Do you demand your rights? Do you rely on the powers and kingdoms to protect you? Do you believe that success is found within advantage? When the idea of giving up such securities crosses your mind do you think you have to stop thinking foolishly and get yourself back to reality? If you instead give into that "foolishness", you practice what the foot-washing, cross-bearing, risen Christ did.
