Many people refuse to believe that there is a Real hell reserved for those that do not meet the mark. They say surely God wouldn't burn anyone up forever. But, if you can believe there is an everlasting reward, you should just as well understand that there is an everlasting punishment!
"And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt." [Daniel 12:2]
