In Rob Bell's book, Love Wins, he presents the belief that hell is here on earth. Hell is the pain and suffering, here, now. This isn't a new idea that Bell is presenting.
For example, here is a video of Ronnie James Dio talking about his views on religion, and in particularly, heaven and hell, since the name the first Black Sabbath album he was singer for was entitled, Heaven and Hell. In this video, he explains what heaven and hell both mean to him in that song...
The answer to the existence of heaven and hell, however, shouldn't be based on the beliefs of a rock singer, or any human for that matter. How can any of us know for certain what lies after death... unless that has been revealed to us by God.
We need to be careful to not let our own feelings and thoughts get in the way of what God has revealed to us in his Word. What does God's Word say about the existence of hell?
Matthew 10:28 says, "Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the one who can destroy both soul and body in hell."
A clear reading of this passage, indicates that the soul goes on after the death of the body. In fact, there is the indication that the soul will be reunited with the body in the future and both will be in hell.
This of course is not good news. This is God's law that brings wrath and judgment. However, there is freedom from sin, death, devil, and hell. If you don't know John 3:16, please look it up.
