The Religious Right is dying. Compassionate Evangelicalism and Progressive Christianity are on the rise and growing.
I wouldn't be surprised if there's a "Religious Left" equivalent to the Religious Right that starts making its way into the mainstream political consciousness in the 2020s or early 2030s.
I've never identified as a member of the "Religious Right", and I find guys like Pat Robertson and Ralph Reed more than a little smarmy.
I do believe, however, in the Bible as the Infallible Word of God. As such, that has implications for my voting. I've not always voted for the "pro-life" candidate, for example, but there are certainly reasons in Scripture which would cause me to ask myself why I'm NOT supporting a pro-life candidate. I don't think God views the GOP as "His" party of choice. But I do think God holds me responsible for how I vote, and the implications for that vote on His Will being done.
I would think of your voting patterns this way. We're saved by GRACE, and not by WORKS. And as believers in Christ, we have soul liberty to live our lives. 1 Corinthians 10:23.
You can justify your voting for the pro-choice candidate by saying "I'm covered by grace."
