You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man's self is not kept clean and bright, his glimpse of God will be blurred - like the Moon seen through a dirty telescope. That is why horrible nations have horrible religions: they have been looking at God through a dirty lens.
C. S. LewisBut length of days with an evil heart is only length of misery and already she begins to know it. All get what they want; they do not always like it.
C. S. LewisGoodness is, so to speak, itself; badness is only spoiled goodness. And there must be something good first before it can be spoiled.
C. S. LewisThere have been men before who got so interested in proving the existence of God that they came to care nothing for God himself, as if the good Lord had nothing to do but to exist. There have been some who were so preoccupied with spreading Christianity that they never gave a thought to Christ.
C. S. Lewis
