" Natural Man Cannot Know the Things of God"
Spiritual things can only be judged or discerned by the spiritual man; the natural man can neither judge nor know them. It is not a question of research. One may indeed spend time in doing research, yet he still is ignorant because he lacks a basic factor within him. The natural man is a man of reason, not of spirit; which means he is a man controlled by the soul (and not the spirit). He is, like Adam, a living soul, void of God's Spirit, and therefore unable to know the things of God.
