It is well to note that the Sacred Record makes what is a notable distinction here and in the generally accepted version of the Bible. In the Sacred Record it says that their punishment shall be as a lake of fire and brimstone, not in a lake of fire and brimstone. The pain caused by their wicked acts will cause the unrepentant ones to suffer even as a burn caused by sticky, smouldering sulphur.
In the remorse the wicked have, yet who will not repent, they will be cast out to dwell with the devil and his angels. For them there is no Redemption, and furthermore, they cannot become extinct because there is no provision made for them that remain corrupt thus to escape their follies.
