Here is an interesting reference to holy spirit:
Acts 8:26- And the angel of the Lord spake unto Philip, saying, Arise, and go toward the south unto the way that goeth down from Jerusalem
unto Gaza, which is desert.
27- And he arose and went: and, behold, a man of Ethiopia, an eunuch of great authority under Candace queen of the Ethiopians, who had the
charge of all her treasure, and had come to Jerusalem for to worship,
28- Was returning, and sitting in his chariot read Esaias the prophet.
29- Then the spirit said unto Philip, Go near, and join thyself to this chariot...
If by now, after reading all these many scriptures (in order from Genesis!), you are still thinking the Holy Spirit might be a GHOST-God- why was the ANGEL there with Philip?
To me, it's easy to see that God was guiding both the angel and Philip WITH His spirit (Breath) - His POWER that his servants are "Filled" with, which is "Poured" out and divided. Not Coming Himself and bringing an angel to relay a simple message...
We all have to choose for ourselves!
