Your life is useful. If you don’t want it, don’t throw it away. Give your life to others who can use it. Volunteer. Look for opportunities to help wherever you can. A life spent solely in the service of one’s self is wasted. Become important to someone else. That is the true reason for living. [1 Peter 4:10]
As for the general view that the Church was discredited by the War—they might as well say that the Ark was discredited by the Flood. When the world goes wrong, it proves rather that the Church is right. The Church is justified, not because her children do not sin, but because they do.
