Prayer is request. The essence of request, as distinct from compulsion, is that it may or may not be granted. And if an infinitely wise Being listens to the requests of finite and foolish creatures, of course He will sometimes grant and sometimes refuse them.
C. S. LewisThe naturalists have been engaged in thinking about Nature. They have not attended to the fact that they were thinking. The moment one attends to this it is obvious that one's own thinking cannot be merely a natural event, and that therefore something other than nature exists. The Supernatural is not remote or abstruse; it is a matter of daily and hourly experience, as intimate as breathing.
C. S. LewisCreatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water...If I find in myself a desire, which no experience in this world can satisfy, the most probable explanation is that I was made for another world.
C. S. LewisIf God 'foresaw' our acts, it would be very hard to understand how we could be free not to do them. But suppose god is outside and above the Time-line... You never supposed that your actions at this moment were any less free because God knows what you are doing. Well, He know your tomorrow's actions in just the same way--because He is already in tomorrow and can simply watch you. In a sense, He does not know your action till you have done it: but the moment at which you have done it is already 'NOW' for Him.
C. S. Lewis
