The God of Abraham

Joshua Zeitz's new book, "Lincoln's God: How Faith Transformed a President and a Nation," is a gamble, since Lincoln never handed out descriptions of what his religion was. He is the only president never to have joined a church, never to have been baptized, never to have taken communion, and attempts to lure affirmations (or denials) from him on religious topics usually fizzed away evasively into qualifications and metaphors.
