The Functions of the Three Parts of Man:
The Function of the Body
The Organ for Mans Existence
Mans physical body, the least mysterious of his three parts, is simply Gods provision for his existence. Without this body, man is not able to exist within the physical realm. When a mans body dies, the man himself ceases to exist. Thus, mans existence altogether depends on the functioning of his physical body (Witness Lee, Basic 10-11).
