I miss the media reports on how many people "incorrectly" fail to identify Obama as a Christian; even as recently as a year ago: "just 34 percent of Americans correctly identify Obama as a Christian". I am a Christian. I've read and studied the Bible for decades. While there are a broad range of understandings that I accept as reasonable, I have never met a Christian who honestly interprets scripture as anything like Obama's positions. Obama is very clearly on the other side in the battle between good and evil.
As for lines in the Bible that are difficult, I know the feeling, although I respond very differently from those who claim to speak for God but from the far left. There are several passages that I find confusing, challenging, or otherwise disconcerting. My general assumption, which should make sense to any Christian, is that if my views disagree with God's, I should re-read the Bible and see if I misunderstood. If I understood the Bible correctly and still want to act differently, I'm wrong and will try to follow God's word. It's not hard. Life doesn't get any better than following the Creator of the universe. He is far more likely to make the most perfect decisions possible for my life than I am, and so far He has done a much better job than I could possibly have done alone. I just have to look at Obama, Weiner, Clinton, and the rest of those who follow darkness instead of Light - there but for the grace of God go I.
