Let me ask you a question: If you went to the airport and were told there was a 10 percent chance your flight was going to crash, would you get on board? No, of course not. It would be too great a gamble to risk taking that flight.
And yet that's exactly what you're doing with your soul. What if there is only a 10 percent chance that you're wrong, and that hell actually does exist? (I'll get to hell's reality in a moment.) Why gamble with your soul -- which is exactly what you're doing? After all, you can't prove that hell doesn't exist; you only hope it doesn't.
But hell does exist; it isn't just something religious people dreamed up. I know it because Jesus warned us about it -- and Jesus spoke with the full authority of God Himself. He called hell a place of "darkness, where there will be weeping and gnashing of teeth" (Matthew 25:30). As I've often said, not one word in the Bible about hell would ever make you want to go there.
My real question for you, however, is this: Why do you reject hell -- and God and Jesus? The reason, I suspect, is because you want to run your own life. But that's a dead-end road, and I urge you to stop and reconsider. God loves you, and Christ died for you. Don't gamble with your eternal soul, but repent of your sins and give your life to Christ without delay. You'll never regret it -- never.
