What is there to live for?

In Where Love Is, God Is, Leo Tolstoy tells the story of Martin the Cobbler who despairs after losing all of his family to death. A priest tells him that he must trust the perfect will of God.

"As to your despair, that is because you live for your own happiness."

"What else is there to live for?"

"For God. For the glory of God."

"How do I do that?"

"Christ showed us the way."
