The full version of Professor Carwardine’s essay appears on p. 223-48 of Our Lincoln.
Naturally, you’ll want to look at three of his book length studies (including a recent biography of Lincoln) of the issues he raises in this essay:
Evangelicals and Politics in Antebellum America ( New Haven: Yale University Press, c1993)
Lincoln: A Life of Purpose and Power (New York: Knopf, 2006)
Transatlantic Revivalism: Popular Evangelicalism in Britain and America, 1790-1865 (Westport, CT.: Greenwood Press, 1978)
For other materials, printed and online, I’ll refer you to George Rable’s essay on “Lincoln’s Civil Religion” in our December 2005 issue:

and my suggested sources for that earlier essay:
/historynow/12_2005/ask2d.php
I can add a pair of useful additions to the online sources available then. The first is an essay in a scholarly journal now available (free)on the Web:
Michael Nelson, “Fighting for Lincoln’s Soul,” Virginia Quarterly Review (2003)
http://www.vqronline.org/articles/2003/autumn/nelson-fighting-lincolns-soul/
And the second is this contribution to the “Teacher’s Parlor” collection of lesson plans at Northern Illinois University’s Lincoln Website:
Dirst, Tara L. “The Importance of Religion in Political Life in the 19th Century: Abraham Lincoln's Experience”
