The fourth degree of Love

God has made all for His own glory (Isa. 43:7), so that man should not even love self save for God’s sake.
To reach this state is to become godlike. As a drop of water poured into wine loses itself, and takes the color and savor of wine; or as a bar of iron, heated red-hot, becomes like fire itself, forgetting its own nature; or as the air, radiant with sun-beams, seems not so much to be illuminated as to be light itself; so in the saints all human affections melt away by some unspeakable transmutation into the will of God.

(Bernard of Clairvaux, On Loving God Ch. 10)
