Mr. Obama doesn’t have a preacher. He’s boasted in the past of having a “healthy skepticism of organized religion” that he got from his agnostic mother.
He is on record in 2004 saying that sin is anything that goed against “his values” (Obama’s, not God’s).
He says that going against those values are their own punishment. God won’t punish those who doesn’t believe in Jesus as the Savior, the Way. He is agnostic as to whether there is any ultimate payoff for good or bad works. He sees Jesus as a historical figure. And it was considered “bad form” to push Obama on the Christian questions all the while the media was prodding GOP candidates with questions on evolution, creation (God as creator, not necessarily even a 6,000 year old world), polygamy, magic underwear, etc.
