Except, I think that they clearly are talking about a death that is both physical and spiritual. CT's point seems to be that if I don't tell you that you are going to be tortured forever in Hell (which is not stated anywhere in Scripture), then you are not going to have any motivation to believe the Gospel. However, Jesus, Paul, and the other biblical evangelists saw the Gospel in terms of death vs. eternal life, not hell vs. heaven. They take something that everyone is already familiar with (death) and offer an alternative (eternal life). And, the means by which we receive eternal life is the power by which God raised Christ from the dead (i.e., resurrection). So, the promise of the Gospel is not that, if we believe, we will never physically die; it is that, through faith, we have the promise of resurrection, which is both physical and spiritual. And, the very notion of resurrection and eternal life as a fate for faithful believers absolutely precludes the notion of Hell as an eternal torture chamber, as the dead do not experience pain or pleasure.
So, ultimately, the idea that I can scare the hell out of you, by telling you about this place of eternal torment that some Christians believe you will go to when you die is rather silly. Instead, I can do as the evangelists in Scripture do and tell what you already know (that you will die and will be dead forever), but that I believe that there is a solution, if you want it, and that God's plan is better than death.
