I'm trying to make a song which feels like a combination of the Beatles song Something, The Association's songs Cherish and Never My Love, and The Twelfth Of Never first recorded by Johhny Mathis. The question indirectlyposed in beginning of the chorus actually does have an answer. The Church of Jesus Christ of Latter-Day Saints does believe that husbands and wive, and other family members across generations, can be united as families in the afterlife (which is what Mormons build Temples for). I'm not aware of any other religion that has that idea as a doctrine, though I've met individuals who believe that.
