I cannot think of one single liberal position, objective, concept, belief, persuasion, tenet, ideology, principle, solution, theory, viewpoint, or conviction of the left in any matters of governance, economics, environmentalism, social issues, or even religion that are not diametrically opposed to the clear teachings of the Word of God. In fact, I think the term "liberal Christian" is an oxymoron.
So there's the challenge. If you can think of any position of the left that is compatible with a truly biblical Christian worldview, please let me know. And, if you are successful, I will publicly repent here on my blog.
