OK...I stand corrected. He does say he is a Christian there, if a rather indifferentist one.
You need to read the article a bit closer. Obama DOES NOT have a Christian worldview.
He is quoted as saying:"I am a Christian.… So, I have a deep faith. I'm rooted in the Christian tradition. I believe that there are many paths to the same place, and that is a belief that there is a higher power, a belief that we are connected as a people."
Jesus says, I am the Way, the Truth, and the Life. No man comes to the Father, except by Me. John 14:6
