Knowledge of God

If we strive to cleanse our hearts from the passions, then according to the amount that we have purified ourselves, Divine Grace will open the eyes of our hearts to the vision of the true Light; for as it is written, Blessed are the pure in heart, for they shall see God (Mt. 5:8), but only when we perfect ourselves through humility, for through humility the mysteries are revealed. - St. Macarius of Optina
