Authentic life is what we are after. "And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.  As for you, the anointing which you received from Him abides in you, and you have no need for anyone to teach you; but as His anointing teaches you about all things, and is true and is not a lie, and just as it has taught you, you abide in Him...always bearing about in the body the dying of Jesus, that the life also of Jesus may be manifested in our body. For we who live are always delivered unto death for Jesus' sake, that the life also of Jesus may be manifested in our mortal flesh" (Luke  10.27, 1 John 2.27, 2 Cor. 4.10-11).

Spirit, Soul, Body

The soulical man or woman is unsaved (unregenerated). The soulish man may or may not be saved. The reason why the soulical man is unsaved is because he lives by his soul ("ical" functions), not able to walk in a quickened spirit because his spirit is dead, insensitive to things of God and smothered by his soul's mind, will and emotion. Therefore, he lives soulishly. Soulical pertains to the functions or area of where the saved or unsaved lives, while soulish speaks of the person who is engrossed in that life.

For example, Watchman Nee says on page 21, Vol. 2 of The Spiritual Man, CFP, "everything belonging to the soulish is defiled and can defile the spirit", not speaking of the soulical since the soulical pertains to the natural functions attributable to the man. The unregenerated man is soulical because he lives in those functions, not in his spirit, nor can he since he is still without God's uncreated life (eternal life as typified by the tree of life) and the Holy Spirit (the life of God). "Upon experiencing the partition of soul and spirit, the latter's intuitive power becomes most keen", and "any contact with what is soulish - whether in themselves or in others - causes their intuitive spirit to feel defiled and to demand instant cleansing" which speaks of the person(s) rather than the area of the functions naturally attributable to the person. Sin is defiling, but so too can what we do in our self-life. This is really where the battlefield ensues, in the battlefield of the mind of our soul which needs the quickening of the spirit and to walk therein, renewing our mind with God's love and truth.

The soul's functions (mind, will, and emotion) are naturally attributes desirable to God in man, but they are not to be the guiding principle since God communicates His life by His Spirit to our spirit, that is, our inner man. Without this "line of communication" we can not commune with God therein, and vanity rules. God communicate His life by entering through the window of our conscience in the seat of intuition, residing there upon initial salvation or new birth. When a person is born-again, his or her old spirit is quickened and a new spirit of eternal life is given.
