Enlightenment:
The Lord came through incarnation to bring God into us and He went through death and resurrection to bring us into God. Both transpire in our spirit. As far as our spirit is concerned, God has been brought into us by the Lord’s coming, and we have been brought into God by the Lord’s going. Yet, as far as our physical body is concerned, we are still here on this earth. In our spirit we have been joined to something heavenly, spiritual, and eternal, but in our body we are still on the earth. In our spirit the Lord has brought God into us and us into God, in our spirit we are one with God, and in our spirit we are in the heavenlies because we are in God. But in our body we are still on earth. As far as our regenerated spirit is concerned, we are no longer the old creation; we are the new creation. However, as far as our body is concerned, we are still in the old creation and on the earth. On the one hand, we are the new creation, we are in God, and we are in the heavenlies. This is true and this is a reality. On the other hand, we are still in the old creation, still on this earth.
Although we have the divine life and have become the church, we are still living in this fallen flesh on the earth. Through the earthly touch we are often dirtied. This is inevitable, for we cannot avoid the earthly touch. Our feet are the members of our body that touch the earth. Day by day we are touching the earth with our feet. In the ancient days of Judea, the people went almost everywhere by walking, by contacting the earth with their feet. Whenever they contacted the earth, their feet certainly became dirty. Consequently, foot-washing was a necessity for them. Spiritually speaking, it is the same for us.
Dirtiness is different from sinfulness. To be sinful is one thing and to be dirty is another. You may be absolutely sinless and yet be very dirty. Perhaps nothing is wrong, but you are dirty simply because of the earthly touch. Do you realize that we are still in the body and are still walking on this earth? We constantly touch the earth, and this makes us dirty. As a result, much of the time we are not clean. Therefore, we need foot-washing.
