I just wanted to pass along some of the reading I did last week on the issue of lust, sexual sin, fornication, and pornography. There are a few books and articles that I will not list do to its content, but this is a good list to get you started:
Joshua Harris - Sex is Not the Problem (Lust Is): Sexual Purity in a Lust-Saturated World - this was the best and most important book I read. I highly recommend that everyone (young and old) read this book.
David Akin - God on Sex: The Creator's Ideas about Love, Intimacy, and Marriage - This is a great book on Song of Solomon.
Craig Gross - Dirty Little Secret: Uncovering the Truth Behind Porn - This is more of a book about revealing the darkness of the porn industry. Its a call for Christians to respond to the pornography problem especially addiction.
Dr. R. Albert Mohler, Jr. - Desire and Deceit: The Real Cost of the New Sexual Tolerance - Everything Mohler writes is worth writing.
Stephen Arteburn - Every Man's Battle - This is standard reading on the issue of fighting lust.
Emerson Eggerich - Love and Respect: The Love She Most Desires, the Respect he so Desperately Needs
CJ Maheny - Sex, Romance, and the Glory of God: What Every Christian Husband Needs to Know - This is a must read for every engaged and married man. Its a short and very important book.
Jim Burgen - What's the Big Deal About Sex? Loving God's Way - This is by far the easiest read on the issue of sex available, especially for young people. The author covers every major topic from a biblical perspective. I read this when I was a teenager and we went through it when I was a youth pastor. Plus, Amazon has used copies starting at a penny!
Richard and Sharon Phillips - Holding Hands, Holding Hearts - Recovering a Biblical View of Christian Dating - This is the most comprehensive treatment of what the Bible says about dating. Highly recommend.
Mark Driscoll and Gerry Breshears - Death By Love: Letters From the Cross - this is one of my favorite books of all time. Though it isn't about sex or lust, the authors take real life issues (including sexuality) and show how the cross shows us how to deal with them.
This should get you started. More could be added and I may add more later. Hope this helps!
