Strictly speaking, there are no such things as good and bad impulses. Think...of a piano. It has not got two kinds of notes on it, the 'right' notes and the 'wrong' ones. Every single note is right at one time and wrong at another. The Moral Law is not any one instinct or set of instincts: it is something which makes a kind of tune (the tune we call goodness or right conduct) by directing the instincts.
C. S. LewisThe Scotch catechism says that man's chief end is 'to glorify God and enjoy Him forever.' But we shall then know that these are the same thing. Fully to enjoy is to glorify. In commanding us to glorify Him, God is inviting us to enjoy Him.
C. S. LewisWhen He [God] talks of their losing their selves, He means only abandoning the clamour of self-will; once they have done that, He really gives them back all their personality, and boasts (I am afraid, sincerely) that when they are wholly His they will be more themselves than ever.
C. S. LewisProsperity knits a man to the world. He feels that he is finding his place in it while really it is finding its place in him. His increasing reputation, his widening circle of acquaintances, his sense of importance, the growing pressure of absorbing and agreeable work build up in him a sense of being really at home on earth which is just what we want.
