The Holy Spirit opens up the Heavens
The Spirit restores our original beauty and fills us with his grace, leaving no room for anything unworthy of our love. The Spirit frees us from sin and death, and changes us from the earthly men we were, men of dust and ashes, into spiritual men, sharers in the divine glory, sons and heirs of God the Father who bear a likeness to the Son and are his co-heirs and brothers, destined to reign with him and to share his glory.
In place of earth the Spirit reopens heaven to us and gladly admits us into paradise, giving us even now greater honour than the angels, and by the holy waters of baptism extinguishing the unquenchable fires of hell.
Speaking quite literally, and also in harmony with the words of water and the Spirit, John the Baptist says of Christ: He will baptize you with the Holy Spirit and with fire. Since we are only vessels of clay, we must first be cleansed in water and then hardened by spiritual fire – for God is a consuming fire. We need the Holy Spirit to perfect and renew us, for spiritual fire can cleanse us, and spiritual water can recast us as in a furnace and make us into new men.
