In politics– as in other aspects of our world– one's hands are going to get “dirty”. Of course, less dirt is preferable to more– and much less dirt is much more preferable. One decides such things as a matter of conscience and principles– such as they are, rather than as we imagine them to be. And so Tim Kaine's pro-abortion Catholicism; and so Ted Cruz's Christian lack of charity; and so “liberals” who embrace a profoundly illiberal presidential candidate; and so “social conservatives” who French-kiss a crass lech; and so on. We all fool ourselves– but this election has revealed many things, including that some of us fool ourselves a lot more than others.
One way in which we should all dirty our hands– Christians especially– is in ministering to others, in the hard work of glorious marriages, effective parenting, and a robust fulfillment of the Great Commission's call to making disciples who can make disciples. If you're not doing that, what's the point anyway?
