THE SPIRITUAL MAN - Watchman Nee
Of these three elements the spirit is the noblest for it joins with God.
The body is the lowest for it contacts with matter. The soul lying between them joins the two together and also takes their character to be its own.
The soul makes it possible for the spirit and the body to communicate and to cooperate. The work of the soul is to keep these two in their proper order so that they may not lose their right relationship ---namely, that the lowest, the body, may be subjected to the spirit, and that the highest, the spirit, may govern the body through the soul. Man's prime factor is definitely the soul. It looks to the spirit to give what the latter has received from the Holy Spirit in order that the soul, after it has been perfected, may transmit what it has obtained to the body; then the body too may share in the perfection of the Holy Spirit and so become a spiritual body.
The spirit is the noblest part of man and occupies the innermost area of his being. The body is the lowest and takes the outermost place. Between these two dwells the soul, serving as their medium. The body is the outer shelter of the soul, while the soul is the outer sheath of the spirit. The spirit transmits its thought to the soul and the soul exercises the body to obey the spirit's order. This is the meaning of the soul as the medium. Before the fall of man the spirit controlled the whole being through the soul.
I pray this week has been a blessing to you. I download his book Sit Walk and Stand and I continue to go back to it over and over and always find some new truth I missed before. If you are trying and not receiving anything from his writing put them away and come back to them later. I have had to do this many times and when I go back the truth just leaps into my spirit. I obviously wasn't ready for it sooner--and that's okay.
