'Spirit of God' in the Bible

For what man knoweth the things of a man, but the spirit of a man which is in him? So the things of God also knoweth no one, but the Spirit of God.

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

But she is happier, if she continue as she is, in my judgment; and I think that I also have the Spirit of God.

Therefore I give you to know, that as no one speaking by the Spirit of God, calleth Jesus accursed; so no one can say, Jesus is the Lord, but by the Holy Ghost.
