I have heard many people say " God gives the gift of eternal life ".  But, then they tell me that our life starts within the flesh we're in now.  If you think we have an eternal future then why is it so hard to believe we have been alive forever?  Eternity means forever to me.  No beginning no end.

Also for those who think that before this life you were nothing and after this life you"ll be nothing.  What makes you think that out of eternity you just so happened to show up now?
