Hatter - You make a great point. I hadn't considered the option of random reincarnations. That would definitely provide a foil for boredom.
Another question for which those of you well versed in Bible studies may have an answer, assuming the Bible even covers it:
My grandmother recently passed away. She married my grandfather quite young. They had 5 children together, then he died in an accident after they had been married for about 10 years. Many years later, she married another man with whom she had a very happy 20 year (or so) relationship before he, too, passed away. So after my twice-widowed Grandma finally exited this mortal coil, my brother and I in a moment of levity wondered, which man would she be with in heaven?
Would it be her first love, her first husband, the father of her children? Or the man she spent most of her golden years with, was married to for twice as long, and chose to share a burial plot with?
Will they share her, or will she get to choose for herself?
Xtians believe heaven is a perfect, wonderful place, but I don't think they've really thought it through, especially a scenario such as this.
Does the Bible make any mention of something like this?
