It is not one of the reason I believe…
Not for my belief in God and a spiritual aspect to existence…
And not for my belief in Christianity specifically.
To be frank, it was one of the last theological problems with Christianity which I considered. Why was there so much obsession with the resurrection. It never seemed so important to me. I came to the conclusion that the point was that life is not the end. There is a life after death and it is as rich and full as what what we have now if not more so. That is indeed an important part of Christianity and theologies which try do do away with this are cutting something essential out of Christianity. This IS listed in my reasons for belief in Christianity (number 3).
