I’ve been asked that question numerous times over the past few months. Here’s a brief response:
For whoever’s policies and values you think are most consistent with God’s Kingdom. That’s sometimes hard to tell–but not usually. If you’re going to vote, don’t waste it protecting your agenda. Don’t waste it trying to create the society your flesh thinks ought to be. Seek God’s will on earth as it is in heaven.
A vote is an important thing. However: voting is not the most important thing you can do. Following Jesus faithfully and leading in your church faithfully is the most important thing you can do to influence society.
