John Stackhouse has a post on the Top Ten apologists. He includes:
Mother Teresa–doubts and all–gotta be in the Top Ten
U2 and Arcade Fire: Christians can be cool, musical, and conscientious
Rodney Stark: All of Western history is not too big a canvas to make his case for the (generally positive) influence of Christianity
Tom Morris: Good philosophy (which is simply God’s truth, when done properly) can help your business . . . and your soul, and your family, and your nation . . .
Alister McGrath and John Polkinghorne: A theologian and a priest who pack serious scientific credentials
George Marsden, Mark Noll, and Harry Stout: Evangelicalism and Christianity in general deserve a serious (historical) look
Christopher Parkening: When he plays Bach, the angels listen
Billy Graham and John Paul II: Once you get to know them, they’re not nearly as bad as you thought, and actually pretty impressive . . .
International Justice Mission: Doing some of what needs to be done in some very dark places
World Vision and the Salvation Army: Work worth every dollar anyone gives them
A Rocha: See? Christians care about the environment, too!
The Wittenburg Door: See? Christians can be funny, too!
For me, off the top of my head, I think John Stott would possibly need to be included – he preaches and teaches his heart out. Going back in history, William Wilberforce and his amazing conversion, and then passion to free people, or in a more modern context Martin Luther King, who persevered in the face of opposition. Who is your nomination?
