It is double speak. Everything obama says is for deceptive purposes. His ignorant worshippers can call him “christian” (small c) because he utters these words.
I think it was Frances Schaeffer who talked about those that use “God” words to try to affect a conversation and to beware of them.
You are right, it is double speak, but to me actions speak louder than words and his actions run the gambit between being very hostile to indifferent toward Christianity.
