What did Christianity start with? It started with Jesus Christ and his dying "to save everyone". So the starting point of that religion was death, pain, blood and suffering. That's the first point. The second point is that Christian dogmas negate all the joys that we can get from living, from being alive. Making money, having sex for other reasons, than reproduction, having a good time, getting on in life, is all considered a sin by the Christian religion. The good Christian is the one who goes through life already being dead inside - dead love, joy and happiness. If you doubt my words, read the Bible. It is all written there. The third thing is that death does not bring life. Death brings death. Point. No one's death is going to bring life to you. The Christian religion installs a very lousy program in every one, who practises it. And the program is - you are guilty of terrible things, and in order to save you from your guilt your God died a terrible death for you, so now you have to spend your life repenting those terrible sins of yours. And so every Christian sunconsciously goes through life repenting every enjoyable thing, every enjoyable moment of his or her life. And it is manifested in the amulet they have to wear - a dead body. And ideally a Christian's life has to be spent in hoping to get to the better world after his death.
As for life after death... You know, the strange thing about Christianity is that though the religion itself is death-oriented, Christians are not taught anything about death or dying. My religion honors Life, we have a cult of Life. Nevertheless, our Volkhvs explain us what it is like to die, I have been through some initiations, during which I experienced the feeling of approaching Death. And now I know what it will feel like, when my time to go comes, and I will not be frightened or confused, because I've been through that already, and I know what to expect and how to take everything and what to do. And the way you accept your death, the way you think and the way you feel at the moment of dying, in a great way shapes what happens to you in after-life.
