Christ says, 'Give me all. I don't want so much of your time and so much of your money and so much of your work: I want you....Hand over the whole natural self, all the desires which you think innocent as well as the ones you think wicked- the whole outfit. I will give you a new self instead. In fact, I will give you myself: my own will shall become yours.
C. S. LewisDo you mean to say," asked Caspian, "that you three come from a round world (round like a ball) and you've never told me! It's really too bad for you. Because we have fairy-tales in which there are round worlds and I have always loved them … Have you ever been to the parts where people walk about upside-down?" Edmund shook his head. "And it isn't like that," he added. "There's nothing particularly exciting about a round world when you're there.
C. S. LewisYou 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. LewisAll day I have been tossed and whirled in a preposterous happiness; was it an elf in the blood? Or a bird in the brain? Or even part of the cloudily crested, fifty-league-long, loud, uplifted wave of a journeying angels transit over and through my heart?
C. S. LewisGood and evil both increase at compound interest. That is why the little decisions you and I make every day are of such infinite importance. The smallest good act today is the capture of a strategic point from which, a few months later, you may be able to go on to victories you never dreamed of. An apparently trivial indulgence in lust or anger today is the loss of a ridge or railway line or bridgehead from which the enemy may launch an attack otherwise impossible.
