When you take the Christian point of view to its extreme, life is kind of just a distracting, trap-filled stopover on the way to eternity. The saddest thing about the eternity myths is that people trade in a lifetime of freedom and enjoyment for an empty promise. In its purest form, Christianity is a sort of apocalyptic escapism. The truth is that earthly enjoyments are the only things we can be sure we will ever have. Without that kind of baggage dragging us along, we are free to enjoy life as it is.
Life is precious because there is so little of it.
As a Christian, the worst thing for me was the persistent sense of guilt. Torment and torture on the cross are the symbol of Christianity. We must open ourselves up to persecution and be on constant look-out for satan's invisible forces and treacherous deceptions. Paranoia, incessant guilt, and shame are all trademarks of Christianity. Yes, you shall know the truth, and the truth shall set you free.
