Every thinking person wants to lead a life of meaning and purpose. For thousands of years, holy books have told us that such a life is available only through obedience and submission to some higher power. Today, the faithful keep popular devotionals and tracts within easy reach on bedside tables and mobile devices, all communicating this common message: Life is meaningless without God. Former pastor Dan Barker eloquently, powerfully, and rationally upends this long-held belief in life-driven purpose. Offering words of enrichment, emancipation, and inspiration, he reminds us how millions of atheists lead happy, loving, moral, and purpose-filled lives. Practicing what he preaches, he also demonstrates through his own personal journey that life is valuable for its own sake-that meaning and purpose come not from above, but from within.
