“Again, it is certain that man never achieves a clear knowledge of himself unless he has first looked upon God’s face and then descends from contemplating Him to scrutinize himself. For we always seem to ourselves righteous and upright and wise and holy–this pride is innate in all of us–unless by clear proofs we stand convinced of our own unrighteousness, foulness, folly and impurity. Moreover, we are not thus convinced if we look merely to ourselves and not also to the Lord, who is the sole standard by which this judgement must be measured.”
~ John Calvin
