 If anyone ever asks you how you know that the Holy Spirit is God, here's how you can explain it. Number one, the Holy Spirit is omnipresent. Where can I go from your Spirit? Where can I flee from your presence? If I go up to the heavens, you are there. If I make my bed in the depths, you are there. Psalm 139, 7 and 8. Number two, the Holy Spirit is omniscient. First Corinthians 2, 10 and 11. But it was to us that God revealed these things by His Spirit. Four, His Spirit searches out everything and shows us God's deep secrets. No one can know a person's thoughts except that person's own Spirit, and no one can know God's thoughts except God's own Spirit. Number three, the Holy Spirit's power is equated with the power of the Most High. Thus, the Holy Spirit is omnipotent. The angel replied, the Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the baby to be born will be holy, and he will be called the Son of God. The Holy Spirit is omnipresent, omniscient, and omnipotent. Therefore, the Holy Spirit is God.
