This is not just another book about the problem of evil. It is more specific and more radical. The focus is not on spectacular calamities, but spectacular sins. The question is not, Where was God in the storm? but, What is God's design in sin?
Piper's claim is that God does not just rule the wind; he rules wickedness, your sin, and the sin of those who have hurt you. How can this be good news--for you and for the world? That is the question. Piper answers with unswerving allegiance to God's Word. And it is good news.
