'Spirit of God' in the Bible

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

Now we have received, not the spirit of the world, but the Spirit of God; that we might know the things that are graciously bestowed upon us by God:

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

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

but she is happier, in my opinion, if she continue as she is: and I think I have the Spirit of God.

I must acquaint you, that no one speaking by the Spirit of God, calleth Jesus a curse: and no one can say that Jesus is the Lord, but by the holy Ghost.
