Truth and falsehood are opposed; but truth is the norm not of truth only but of falsehood also.
C. S. LewisThe human heart is not unchanging (nay, changes almost out of recognition in the twinkling of an eye).
C. S. LewisSomething of God... flows into us from the blue of the sky, the taste of honey, the delicious embrace of water whether cold or hot, and even from sleep itself.
C. S. LewisNow we cannot...discover our failure to keep God's law except by trying our very hardest (and then failing). Unless we really try, whatever we say there will always be at the back of our minds the idea that if we try harder next time we shall succeed in being completely good. Thus, in one sense, the road back to God is a road of moral effort, of trying harder and harder. But in another sense it is not trying that is ever going tobring us home. All this trying leads up to the vital moment at which you turn to God and say, "You must do this. I can't.
