His POWER (not a 'Ghost-God') that guides, empowers, encourages, and instructs is the
"Power of the Most High".
1 Cor 2:10- But unto us God revealed them through the spirit: for the spirit searcheth all things, yea, the deep things of God.
11- For who among men knoweth the things of a man, save the spirit of the man, which is in him? even so the things of God none knoweth, save the spirit of God.
12- But we received, not the spirit of the world, but the spirit which is from God; that we might know the things that were freely given to us of God.
13- Which things also we speak, not in words which man's wisdom teacheth, but which the spirit teacheth; combining spiritual things with spiritual words.
14- Now the natural man receiveth not the things of the spirit of God: for they are foolishness unto him; and he cannot know them, because they are spiritually judged.
15- But he that is spiritual judgeth all things, and he himself is judged of no man.
16- For who hath known the mind of the Lord, that he should instruct him? But we have the mind of Christ.
Note; there is OUR spirit, God's spirit, and the WORLD'S spirit; the Bible isn't talking about Ghosts!
