'Spirit of God' in the Bible

For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God.

But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised.

Do you not know that you are a temple of God and that the Spirit of God dwells in you?

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

Therefore I make known to you that no one speaking by the Spirit of God says, “Jesus is accursed”; and no one can say, “Jesus is Lord,” except by the Holy Spirit.
