If it’s been said once it’s been said a thousand times: Jimmy Carter may have been a very unsuccessful U.S. president, but his life after the White House has been top-notch.

In fact, according to a 2015 poll, the American public thinks he’s No. 1 among the nation’s post-presidents.

Obviously, there was that Nobel Peace Prize in 2002, which was awarded for “his decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development." But if you ask average Americans what they admire about Carter’s life post-White House, I think most of them would mention two, or maybe three, parts of his life.

First, there is his record in volunteer work and public service, symbolized by decades of work with Habitat For Humanity building homes for the working poor. If you have followed that story at all, you know that Carter doesn’t just show up with a hammer for the photo-ops. Second, there is the remarkable marriage-partnership between Jimmy and Rosalynn Carter. I have heard Southerners refer to them as the “anti-Clintons,” as in Bill and Hillary Rodham.

Finally, there is — as Jerry Falwell, Jr., of all people, once put it — Carter’s many decades of work as the “world’s most famous Sunday school teacher.” Ths smiling Baptist did that work week after week whether there were TV cameras present or not.

That faith element was the subject of this week’s “Crossroads” podcast (click here to tune that in) in which host Todd Wilken and I looked at three mainstream-press features about Jimmy and Rosalynn Carter celebrating their 75th wedding anniversary. If readers are interested in the faith tie that binds in this marriage, they should start with this fine Washington Post feature, with it’s one-word headline: “Inseparable.” Here’s the overture:

PLAINS, Ga. — When they arrived, they strolled hand-in-hand toward their pond with a graceful willow at its edge.

“We’re going to be buried right there, on that little hill,” Jimmy Carter said, motioning toward the lawn sloping up from the pond.
