You can gamble that I am wrong, but are you willing to risk it? Imagine this scenario: A gambler loses all his money in Las Vegas. The casino offers one last wager—

"If you win, you get all your money back. If we win, then two of our security men will haul you down to the basement and toss you into our huge roaring furnace."

Obviously, nobody in their right mind would risk those consequences. Yet, this is the gamble you take every day you reject Christ. If you die, you are guaranteed an eternity in the flames of hell.
