The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. The spiritual person judges all things, but is himself to be judged by no one. “For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ. (1 Corinthians 2:14-16)

The Greek word for ‘mind’ is νοῦς nous, which is a loan word, ‘nouse’, in English, colloquially meaning ‘know-how’ or ‘common sense’; this is close to the Biblical sense of νοῦς, being ‘understanding’ and referring more to faculty of reason than the other Greek word for mind, ψυχή, psyche, which is more the containment or vessel of that faculty, and thus is understood to represent the soul.  

Broadly speaking human knowledge of God can be said to be threefold in nature, innate, informed or inspired.  The Bible shows that we may inherently know of God’s existence, need testimony as to His character, but knowledge of God’s mind, our Godly ‘nouse’, falls into last category, that of revelation.
