Eternity asks 

Eternity asks you and every individual in these millions and millions only one thing: whether you have lived in despair or not, whether you have despaired in such a way that you did not realize that you were in despair, or in such a way that you covertly carried this sickness inside of you as your gnawing secret... or in such a way that you, a terror to others, raged in despair.

The Sickness Unto Death,
a book written by Danish philosopher Søren Kierkegaard in 1849 under the pseudonym Anti-Climacus.
