The truth is that certain people love evil so much that they would not believe in Him and His goodness, no matter what...Even if they saw Him do great and mighty things, they hate what He is and they love evil and death. Some people will never believe no matter what. These people are destined to be cast into utter darkness, and to suffer with the evil forces and powers that they serve.
Re 20:10 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.
