1st - there is no "Christian Hell" because they've been redeemed from corruption by the Blood of the Lamb<quoted text>
What does temperature at Earth's core have to do with it? Are you really naive enough to believe the Christian Hell is actually located inside our planet? Is that actually what you're implying?
2nd - you'll know soon enough if there's a hell for the unredeemed and where it might be. are you the crazy reckless gambling sort?
