Saint Augustine Ignorant Quotations

If I am given a formula, and I am ignorant of its meaning, it cannot teach me anything, but if I already know it what does the formula teach me?

It will not be held against you that you are ignorant against your will, but that you neglect to seek out what it is that makes you ignorant; not that you cannot bring together your wounded limbs, but that you reject Him that would heal them.

No one knows what he himself is made of, except his own spirit within him, yet there is still some part of him which remains hidden even from his own spirit; but you, Lord, know everything about a human being because you have made him...Let me, then, confess what I know about myself, and confess too what I do not know, because what I know of myself I know only because you shed light on me, and what I do not know I shall remain ignorant about until my darkness becomes like bright noon before your face.
