Screwtape on courage

This, indeed, is probably one of the Enemys motives for creating a dangerous world—a world in which moral issues really come to the point. He sees as well as you do that courage is not simply one of the virtues, but the form of every virtue at the testing point, which means, at the point of highest reality. A chastity or honesty, or mercy, which yields to danger will be chaste or honest or merciful only on conditions. Pilate was merciful till it became risky.
