It does speak of it, but it does not necessarily specify the "eternal hell if you don't believe" stance that some denominations have promulgated.
There are several possibilities that are not at all easily dismissed by reference to scripture itself...
1. That it is spoken of allegorically
2. That it references "destruction of the soul" rather than "suffering of the soul" (per Christ's use of "destroy the soul in hell")
3. That it is a temporary, not permanent state
4. That it is the final dispensation of the truly evil, not simply on the basis of non-belief (otherwise a review of one's actions from the "Book of Life" seems rather superfluous)
I would exercise extreme caution in stating that one -knows- what God will do, as this is in a sense us telling God what he has to do, on a judgment that is explicitly stated to be made by him in the future (the "Last Judgment"--not a "Show Trial"), but...
I'd suggest taking a look at Conditionalism and its associated Annihilationism as stances that are quite harmonious with scripture, and address some arguments regarding "fairness"--one could say that atheists in general ultimately get exactly what they expect (and demand), per their own worldview.
