OTH, this recognition is also considered analytically, death implies life, the finite implies the infinite. Koyré says this is a Cartesian argument. Koyré suggests instead a fear of death gives rise to the projection of immortality, or the hope of prolonging finitude. b>AlbionGirl seems to suggest this with "always wanting to be able to."
But this too, is again the hope of human desires to participate in what it fears it doesn't have: authenticity. And what is more authentic than a consciousness or efficacy of continued existence? In one sense it makes no difference if this takes the form of a self-assertive ego like a Sartre trying authenticate living for himself or another who yields to whomever or whatever is deemed to have it. Either way, what must be had, can't be had but with a faith (and it need not be christian). Although when such a participation is considered a gift, it is more nearly christian.
cornelis, your analysis is brilliant. To carve out my own response to it, I'd start by saying there is a huge difference between a Sartre "trying [to] authenticate living for himself" and a christian "who yields to whomever or whatever is deemed to have it" [i.e., Life] -- which is ultimately God.
Sartre has no way to authenticate his own existential expeiences outside of his own personal resources. No wonder he is so anxious, so filled with distrust for the hellish "Other."
The christian, on the other hand, yields his existential experience to a judgment that is not conducted from his own internal resources. By this means, he is able to find both place and peace in this world.
But this does not mean the "christian-type mentality" will necessarily fall under the spell of the next slick shaman to come down the pike: Fundamentally, it seems to me the human spirit is quite discriminating about the things going on in its constituting environment (so to speak). IMHO.
It is precisely this putative human "instinct" for truth that comes most under attack these days -- so to get it to "doubt itself."
I'm sure in our modern world we will not lack for different points of view in regard to which is the "better" way to live a human life: Chronic existential angst, self doubt, and the ever-abiding keen skepticism about the motives, projects, and goals of the "hellish Other"; or an abiding sense of place and purpose in a Creation that is founded on ideas of love and mutual cooperation....
