In the mighty power of God, who is both God and human, and in every place–for his power extends everywhere–the faithful must be empowered by the four Evangelists, pondering God’s precepts and filled with virtuous prudence, so that they may understand from where they’ve come and what they will become. For God is fire, and his angels, from time to time, announce to humankind his miracles and the wonders of his throne. They are burning spirits, who shine before his face and who are so on fire in their love for him that they desire nothing other than what he wishes.
