This seems to come up now and again, so I thought I would put out there that the answer is: Yes. This is the United States of America! everyone should be involved in how our government operates. Now since being a follower of Jesus is not a part time thing, you don’t get to hide your faith away from the public sector either. Does this mean that you should only support christians? no. It should ensure that you are most supportive of men and women of good character though. And towards those politicians that claim that they are christian, we should keep track of their actions and votes.
While we are not the judges of their hearts and salvation, we can indeed judge the fruits that they produce. If you say you’re a Duck but act like a Coyote I’m liable to toss you back out of office on the next election cycle.
I know we’re all busy, but politicians do need to be kept track of, so that you can know that they are doing what they said they would do. That is the only way to weed out those who don’t belong. Or better still… call and write them so that they know what their voters think on different issues. That can help keep things on track between elections.
