If you have once accepted Christianity, then some of its main doctrines shall be deliberately held before your mind for some time every day. That is why daily prayers and religious reading and churchgoing are necessary parts of the Christian life. We have to be continually reminded of what we believe. Neither this belief nor any other will automatically remain alive in the mind. It must be fed.
C. S. LewisIf you live for the next world, you get this one in the deal; but if you live only for this world, you lose them both.
C. S. LewisNature does not teach. A true philosophy may sometimes validate an experience of nature; an experience of nature cannot validate a philosophy. Nature will not verify any theological or metaphysical proposition (or not in the manner we are now considering); she will help to show what it means.
C. S. LewisCan a mortal ask questions which God finds unanswerable? Quite easily, I should think. All nonsense questions are unanswerable. How many hours are in a mile? Is yellow square or round? Probably half the questions we ask - half our great theological and metaphysical problems - are like that.
C. S. Lewis
