The closest thing that the “WORLD” (I’m being facetious) has to say about eternal life is ‘reincarnation’.
As one who doesn’t even believe in incarnation, may I say they’ve made a noble attempt (facetious!) at explaining it away.
But hey let’s take hope – at least The World is allowing for the possibility of eternal life. Would that they got an inkling of what, when and where Spirit IS !!!
