'Spirit of God' in the Bible

For who among men knoweth the things of man, save the spirit of man which is in him? so also the things of God knoweth no man, but the Spirit of God.

Which things also we speak, not in discourses framed by human wisdom, but taught by the Spirit of God; comparing spiritual things with spiritual.

But the natural man receiveth not the things of the Spirit of God: for they are folly to him: and he cannot know them, because they are spiritually discerned.

Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?

But she is more blessed if she abide as she is, in my opinion: and I think I have the spirit of God.

Wherefore I advertise you, that no man speaking by the Spirit of God, call Jesus anathema: and no man can say, Lord Jesus, but by the Holy Ghost.
