Jesus Is No Accessory to Any American Political Position

It seems to me that too many Christians gravitate to right-wing Republican politics or left-wing Democratic politics because they see some parallel between a political plank and a part of the gospel. It's like saying that the party that uses candles must be the true one because they're shaped so much like sticks of gospel dynamite. The gospel was meant to explode with saving power in the lives of politicians and social activists, not help them decorate their social agenda. 

So John Piper writes in his book on race and the gospel, Bloodlines. Piper goes on to suggest ways that the gospel can transform race relationships, and the personal/political solution to racism. It's not a complete answer for how the gospel interacts with politics, but it's helpful.
