I just started the book last night, but here are a few gold nuggets so far:
"If you add to or subtract from the cross, even if it is to factor in biblically mandated religious practices like prayer and evangelism, you rob God of his glory and Christ of his sufficiency. Romans 8:1 tells us that there is no condemnation for us, not because of all the great stuff we've done but because Christ has set us free from the law of sin and death. My sin in the past: forgiven. My current struggles: covered. My future failures: paid in full all by the marvelous, infinite, matchless grace found in the atoning work of the cross of Jesus Christ."
"There is nothing confining God. His creativity is transcendent because his very being is transcendent. Everything that is is his, and he can make more of anything he wants out of nothing at all. There is no human category for this kind of richness. It makes Bill Gates a pauper, Rockefeller a beggar, and one of those island-owning sheiks in the Middle East a hobo. I don't know what it makes you and me, but it certainly moves us into the perspective of awe that God deserves. Now we get a glimpse of what would move Paul to sing from his soul, "Oh, the depth of the riches and wisdom and knowledge of God!"
"Romans 11:33 tells us instead that God is incomprehensibly immense, exceedingly expansive, and eternally powerful, and so much so that time and time again our response to many of the things of God ought to be "I don't know." Rather than respond to his incalculable God-ness with our slide rules and flowcharts, we would do better to worship him with reverence and awe. How can God see, know, and do all that he does? I don't know."
He talks about worship and why we must talk about Hell in order to fully embrace the Gospel. VERY good stuff.
