The grace of Knowledge in its purest form manifests through us as a revelation about the nature of the Divine. In rare instances, one can have a revelation of knowledge directly from God. Revealed knowledge does not just come through saints and mystics. Revealed knowledge is given to those who are vessels of service to humanity in ways great and small. This is the grace that draws us inward toward the pursuit of the knowledge of God as it expresses itself through our inner yearnings and personal mysteries that cannot be solved or satisfied by the riches of the world.
The three categories of knowledge are information, active knowledge, and gnosis, or knowledge revealed through grace. Your spiritual senses develop through these three levels, moving from organic survival gut instincts to an awareness of inner guidance motivated by personal need and, at last, to a devotion to mystical illumination.
