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. LewisThere is a story about a schoolboy who was asked what he thought God was like. He replied that, as far as he could make out, God was 'the sort of person who is always snooping around to see if anyone is enjoying himself and then trying to stop it.'
C. S. LewisWe are afraid that Heaven is a bribe, and that if we make it our goal we shall no longer be disinterested. It is not so. Heaven offers nothing that the mercenary soul can desire. It is safe to tell the pure in heart that they shall see God, for only the pure in heart want to. There are rewards that do not sully motives. A man's love for a woman is not mercenary because he wants to marry her, nor his love for poetry mercenary because he wants to read it, nor his love of exercise less disinterested because he wants to run and leap and walk. Love, by definition, seeks to enjoy its object.
C. S. LewisMen became scientific because they expected Law in Nature, and they expected Law in Nature because they believed in a Law Giver.
