Christians believe that the Holy Spirit is the third Person of the Trinity. God the Father, and God the Son, and God the Holy Spirit. This would make the Holy Spirit a He. Through out Scripture the attributes of God and a real person are attributed to the Holy Spirit. The Holy Spirit is a He and not an it.
Zeus is the king of the gods and the heavens. Apollo is a son of Zeus and the Titan goddess Leto, his sister is Artemis the goddess of the moon and the hunt; he was the god of the sun and music. Ares was the son of Zeus and Hera, he is the god of war. Hades is the elder brother of Zeus, and god of the Underworld and it's ruler.
