Look, I dearly wish I could be with you when you pop your clogs, just to see the (metaphorical) look on your face when you realise that you've had your leg lifted. There is no heaven, there is no hell, there is nowhere for you to go because there will be no you. There will be some dead flesh & bones that will either be incinerated or left for carrion. Either way, you won't have to worry because you will be D E A D.
The Christian message is simple. Lead a good life and raise your children likewise. When you die you live on (via your children - who are half you genetically) if you've brought them up well they should do likewise and your "spirit" will live with them too. Over time if everyone does so, we create ' Heaven on Earth.' Hell can be seen on many housing estates were generations have taken a different vapproach.
