'Spirit of God' in the Bible

For who of men knows the things of men except the spirit of man in him? so also the things of God no one knows, except the Spirit of God.

And the natural man receives not the things of the Spirit of God: for they are foolishness to him: and he cannot know, for they are spiritually examined.

Know ye not that ye are the temple of God, and the spirit of God dwells in you?

And she is happier if she so remain, according to my opinion: and I also think to have the Spirit of God.

Wherefore I make known to you, that none speaking in the Spirit of God calls Jesus anathema: and none can say Lord Jesus, but in the Holy Spirit.
