Well; the BOOK says...

And I saw the dead, great and small, standing before the throne, and THE BOOKS WERE OPENED. Another book was opened WHICH IS THE BOOK OF LIFE. The dead were judged according to their works as recorded in the books. The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to their works. Then death and Hades were thrown into the Lake of Fire. The Lake of Fire is the second death. If anyone's name was not found written IN THE BOOK OF LIFE, he was thrown into the lake of fire."

2 Peter 2:20-22
20 For if, after they have escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and are overcome, the last state has become worse for them than the first. 21 For it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment handed on to them. 22 It has happened to them according to the true proverb, "A DOG RETURNS TO ITS OWN VOMIT," and, "A sow, after washing, returns to wallowing in the mire."
