I went to attend Summit Ministries in Manitou Springs, CO the last two weeks of August, and I heard Dr. Sean McDowell speak for almost a solid day. He is in my top three favorite speakers that I heard there. His book "Ethix" is a very good overview of what he spoke on, plus some other material that he didn't speak on. The topics range from same-sex marriage versus traditional marriage, to how you should decide what to do with your life. It was definitely worth reading it. I highly recommend that any and every one should read this book.
