I've heard that some folks actually don't look forward to heaven. Reasons? They tend to think that an eternity of doing anything would get old rather quickly. Kind of like overdosing on apple pie here on this side of eternity.
I think we need to give God some credit here. (Funny statement, eh?) I prefer to believe that God has got that boredom problem solved. Sometimes we need reminding that nothing is too hard for God. He has fashioned an existence that will be eternal bliss. That's it. Case closed.
I enjoy reading about near-death experiences. Of course, many doubt their validity...and whether they indeed give us a glimpse of heaven remains to be seen. But I do find it fascinating that many "return" to this life after having experienced, albeit for just a moment, a profound peace, a joy beyond measure. If these NDE's do pull back heaven's curtain a bit, then it seems that God really has covered this base.
So much of our journey is yet to be lived. I don't know much about heaven, such as what "state" we'll be in or how we'll relate to our current spouse given that there will be no marriage there. But I'm exceedingly anxious to be there and to see what He has in store for me. Even if it takes forever.
