The Irony and Tragedy of Sin

Why is it that people can become emotionally and morally indignant over poverty and exploitation and prejudice and abortion and the infractions of religious liberty and the manifold injustices of man against man, and yet feel little, or no, remorse or indignation or outrage that God is disregarded, disbelieved, disobeyed, dishonored, and thus belittled, by millions and millions of people in the world? And the answer is: sin. And that is the ultimate outrage of the universe. -  From "What is Sin" by John Piper
