Spiritual Blindness

In vain does the man attempt to see, whose sight is obscured by the cataract, or by some other equally ruinous disease. Nor is he less blind, over whose spiritual eye sin has drawn its opaque scales and films. Hence it is said in Scripture, "The light shineth in darkness, and the darkness comprehended it not." But break off and purge away the spiritual cataract, and the power of vision will return. In proportion as the eye of the soul is purified from the perplexity of earthly corruptions, does Christ become the true light of the mind; and the beauty of the divine character begins from that moment to unveil itself in all its wonderful perfection. BLESSED  ARE  THE  PURE  IN HEART, FOR  THEY  SHALL SEE  GOD.
