Book excerpt: The Bible has a way of shocking us. If Americans could still blush, we might blush at the words, "Rejoice in the wife of your youth, a lovely deer, a graceful doe. Let her breasts fill you at all times with delight; be intoxicated always in her love" (Proverbs 5:18-19). But, of course, sin always tries to trash God's gifts. So we can't just celebrate sex for what God made it to be; we have to fight what sin turned it into. The contributors to this unique volume encourage you to do both: celebrate and struggle. This book has something for all-men and women, married and single-from contributors like John Piper, C. J. and Carolyn Mahaney, Mark Dever, Al Mohler, Carolyn McCulley, and others.
