The modern habit of doing ceremonial things unceremoniously is no proof of humility; rather it proves the offender's inability to forget himself in the rite, and his readiness to spoil for every one else the proper pleasure of ritual.
C. S. LewisWe are told that Christ was killed for us, that His death has washed out our sins, and that by dying He disabled death itself. That is the formula. That is Christianity. That is what has to be believed.
C. S. LewisOnly those who try to resist temptation know how strong it is. ... We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation meansโthe only complete realist.
C. S. LewisAbove all, do not attempt to use science (I mean, the real sciences) as a defence against Christianity. They will positively encourage him to think about realities he canโt touch and see.
C. S. LewisAfter each failure, ask forgiveness, pick yourself up, and try again. Very often what God first helps us toward is not the virtue itself but just this power of always trying again. For however important chastity (or courage, or truthfulness, or any other virtue) may be, this process trains us in habits of the soul which are more important still. It cures our illusions about ourselves and teaches us to depend on God. We learn, on the one hand, that we cannot trust ourselves even in our best moments, and, on the other, that we need not despair even in our worst, for our failures are forgiven.
