After 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.
C. S. LewisThe time when there is nothing at all in your soul except a cry for help may be just that time when God can't give it: you are like the drowning man who can't be helped because he clutches and grabs. Perhaps your own reiterated cries deafen you to the voice you hoped to hear.
C. S. LewisThe Future is, of all things, the thing least like eternity. It is the most temporal part of time--for the Past is frozen and no longer flows, and the Present is all lit up with eternal rays.
C. S. LewisAnd yet all loneliness, angers, hatreds, envies, and itchings that it contains, if rolled into one single experience and put into the scale against the least moment of the joy that is felt by the least in Heaven, would have no weight that could be registered at all. Bad cannot succeed even in being bad as truly as good is good.
C. S. LewisYou have a traitor there, Aslan," said the Witch. Of course everyone present knew that she meant Edmund. But Edmund had got past thinking about himself after all he'd been through and after the talk he'd had that morning. He just went on looking at Aslan. It didn't seem to matter what the Witch said.
