John Portmann is professor of religious studies at the University of Virginia in Charlottesville. He is the author of When Bad Things Happen to Other People, Sex & Heaven, and Bad for Us.
In this most original and thought-provoking book, Portmann persuasively shows that humans will always sin, though they may attempt to decrease the number and the seriousness of such sins. A must-read, and not only for sinners.--Aaron Ben-Zeev
