Luther and Lewis

[Christ] is pleased when we acknowledge His gifts and thank Him for them; moreover, He gives His blessing so that it becomes better and extends farther than the great riches and excessive possessions of the unbelievers.—Martin Luther, Homily for Trinity 7 AE 78:265

[Screwtape] And how disastrous for us is the continual remembrance of death which war enforces. One of our best weapons, contented worldliness, is rendered useless. In wartime not even a human can believe that he is going to live forever.—C. S. Lewis, Business of Heaven, p. 192.
