I must be missing something ...

Bob Araujo writes in his post:

I could say, “You may be right, Secularist, that it is all over when we die. But I ask you to consider the following: we both will die (however that happens), and this event is inevitable. You may look at me and say, ‘see I (the Secularist) was right. You have wasted a lifetime.’ But, my suggestion to you is this: But if I (the theist) am right, I will not have wasted a lifetime, but you will have wasted an eternity.”

What?  Given that many believers--including many Christians--live morally abominable lives, and given that many nonbelievers live morally exemplary lives, why would Bob think that "the Secularist . . . will have wasted an eternity"?    Surely Bob doesn't think that being a believer is a necessary (though not sufficient) condition of gaining eternity, whatever one means by "gaining eternity".
