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. LewisAll the delights of sense, or heart, or intellect, with which you could once have tempted him, even the delights of virtue itself, now seem to him in comparison but as the half nauseous attractions of a raddled harlot would seem to a man who hears that his true beloved whom he has loved all his life and whom he had believed to be dead is alive and even now at his door.
C. S. LewisIf people knew how much ill-feeling unselfishness occasions, it would not be so often recommended from the pulpit.
C. S. LewisThe Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; or — if they think there is not — at least they hope to deserve approval from good men. But the Christian thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it.
C. S. Lewis
