What art Thou then, my God? what, but the Lord God? For who is Lord but the Lord? or who is God save our God? Most highest, most good, most potent, most omnipotent; most merciful, yet most just; most hidden, yet most present; most beautiful, yet most strong; stable, yet incomprehensible; unchangeable, yet all-changing; never new, never old; all-renewing, and bringing age upon the proud, and they know it not; ever working, ever at rest; still gathering, yet nothing lacking; supporting, filling, and overspreading; creating, nourishing, and maturing; seeking, yet having all things.

Sin is to a nature what blindness is to an eye. The blindness of an evil or defect which is a witness to the fact that the eye was created to see the light and, hence, the very lack of sight is the proof that the eye was meant... to be the one particularly capable of seeing the light.
