The atheist may believe God does not exist let alone hell, but as we look around His creation and existence cannot be denied (Romans 1:18-20).
Jesus spoke about hell in the New Testament more than about heaven, because He did not want anyone to go there! Repentance was always the order of the day, as it is for our time as well (2 Peter 3:9). 9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
The bible does not hide who will go to such a place of eternal torment. So who will be in hell? Scripture teaches the wicked and those who forget God will be there, along with the murderer and liars. Did you know in Gods eyes if we hate our brother it’s as bad as being a murderer? (1 John 3:14-16) (Revelation 22:14-15).
God had to make a hell as there will be those who even after everything falls apart all around them will still not repent and turn to the Lord. It is those most wicked and rebellious of soul’s that will be cast into the lake of fire along with those who were not found written in the Lambs book of life!(Revelation 20:10-15). 10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them.12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.14 And death and hell were cast into the lake of fire. This is the second death.15 And whosoever was not found written in the book of life was cast into the lake of fire.
