'Spirit of God' in the Bible

For what man knoweth the things of a man: save the spirit of a man which is within him? Even so the things of God knoweth no man, but the spirit of God.

For the natural man perceiveth not the things of the spirit of God, for they are but foolishness unto him: Neither can he perceive them, because he is spiritually examined.

Are ye not aware that ye are the temple of God, and how that the spirit of God dwelleth in you?

But she is happier if she so abide, in my judgement. And I think verily that I have the spirit of God.

Wherefore I declare unto you that no man speaking in the spirit of God defieth Jesus. Also no man can say that Jesus is the Lord, but by the holy ghost.
