Here is a selective excerpt:
There is no doubt in my mind that both Romney and Obama described America in such religious and exceptionalist terms because they are trying to win the election. As a nation we want to believe that we are special–a source of categorical good in the world. We want to believe that we are the greatest nation in the world, but more than that, that we are making the world a better place…
…My concerns about such glowing descriptions of America is that they assume things about our nation that may or may not be true. And such assumptions keep us from looking at the state of our union with sober judgement and consequently from seeing our weaknesses and failures. As Christians, we ought to hope that America would be a source of good in the world. But it is the height of hubris to assume that we are the greatest nation in the world. As Christians, we ought to be concerned primarily with God’s judgments over and against the judgments of others. And further, we should be very careful in presuming to speak for [God].
