Where do people get the strength to be so caring, so compassionate, so human in the best sense of the word, if not from a God who renews their strength, who restores their soul when they have depleted their soul, so that they can do what they know is the right thing, even if it is a difficult thing, to do? If depression is the "dark night of the soul", God is the magnetic force that guides people through the dark night and brings them into a brighter world.
— Harold S. Kushner, The Lord Is My Shepherd
