Grace is from God, and works in the depth of the soul whose powers it employs. It is a light which issues forth to do service under the guidance of the Spirit. The Divine Light permeates the soul, and lifts it above the turmoil of temporal things to rest in God. The soul cannot progress except with the light which God has given it as a nuptial gift; love works the likeness of God into the soul.
–Meister Eckhart (1260-1328)
