Crossway Books has now posted an online
PDF of the endorsements, my introduction, and John Piper's essay on "Sex and the Supremacy of Christ" in the book of the same title. The book will also contain a DVD, and I believe Crossway will soon be launching a website where you can watch the plenary sessions of the conference--from which the book derives--streamed through this site. I'll let you know when the site is up and running.
