This cenacle presentation addresses Humility as the "gateway" grace and the one attribute that makes possible our successful participation in the Flame of Love devotion. We discuss how the gifts of grace can be spiritually toxic without humility and how humility and love are two sides of the same coin. We describe the radical freedom of humility — the freedom from fear — the freedom to love. We examine some of the ways Jesus and Mary use to build humility in us using examples from The Spiritual Diary. We explore the idea of humiliation and note humility as the ultimate shield against Satan and the object of his attack.
