OUTWARD MAN AND INWARD MAN.

Paul clearly distinguishes between these two when he said, for which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
The outward man is the physical body and it's five senses organ. These senses are his medium for relating with his environment.
The inward man, however is the woman spirit and his soul. He's the one the Bible calls the hidden man of the heart.
