Piper's new book, Spectacular Sins, arrived on my door step yesterday. Here is just a taste of what you can expect when you read it. Never have I heard anyone talk like this.
"My aim is to show that sin and evil, no matter how spectacular, never nullify the decisive, Christ-exalting purposes of God. No, my aim is more than that. These spectacular sins do not just fail to nullify God's purpose to glorify Christ, they succeed, by God's unfathomable providence, in making his gracious prupose come to pass" (p. 17).
