This is the thesis of Stephen Arterburn and Fred Stoeker in their recently published book Every Man's Battle. Every Man's Battle offers a biblical approach to achieving victory over sexual temptation. The book is salted with many helpful scripture references that are artfully interwoven with a series of brutally honest anecdotes and real-life stories. Having established God's standards for sexual purity, the writers then show how man's standards fall short of God's standards. To aim for obedience is to aim for perfection.
Excellence allows room for a mixture.
