'Thoughts' in the Bible

For what person knows the thoughts and motives of a man except the man’s spirit within him? So also no one knows the thoughts of God except the Spirit of God.

For who has known the mind and purposes of the Lord, so as to instruct Him? But we have the mind of Christ [to be guided by His thoughts and purposes].

and again, “The Lord knows the thoughts of the [humanly] wise, that they are useless.”
