Havin a tough time? Let me recommend Mike Cleveland's "PURITY CHALLENGE".

Description: "Blessed are the pure in heart, for they shall see God." These powerful words from Jesus are the goal of Purity Challenge. As you work through this book you will be directly in the area of sexual purity; but don't lose sight of this great promise found in Matthew 5:8. Seeing God is the point! The prerequisite for seeing God is being pure in heart, and the only way for that to happen is for you to become increasingly captivated by Jesus Christ above all other pleasures. Set up as purity lessons for each day for thirty days. For about 11 bucks, you'll be a changed person! --- (in your local bookstores now).
