Obama has an immutable hardened heart. His lifelong and unaltered commitment to "my [his] Muslim faith" (his very words) assures he'll never have a Saul on the road to Damascus awakening. As a avowed Marxist, a key part of his very being is to hate Christianity and all the Good that it represents.
You're right that such a conversion, as far fetched as it may be, would be utterly stunning. Still, I personally can't envision being in the same Eternal Heaven with the likes of Obama since the treachery and unspeakable evil he has sown here on earth can't be undone.
“Obama has an immutable hardened heart.”
I fear you’re right. I believe that some people are beyond hope, and he’s one of them.
