The God and afterlife paradox.
If there is a life and an afterlife given by God, ( big if, ) and that god is perfect. (Another one.)
Then:
If you don't fully, and perfectly to gods perfect standard, enjoy and appreciate every single minute of this life as a wonder and joy, why should god give you another one ? And if you do fully, and perfectly to gods perfect standard, enjoy and appreciate every single minute of this life as a wonder and joy, why would you want another one ?
The second question is easy: if you enjoy existing, wanting that to continue makes sense.
The first part is all sorts of problematic for Xtian apologists.
