John Shore:

I think keeping the afterlife a complete mystery is God’s way of telling us to pay maximum attention to the life we have on this side of the door. That the ever-fluid now of our life is where the action is. As clearly as he possibly can, I think he’s telling us to with full and focused consciousness be in our lives. To love our lives. To believe in our lives. To trust that within every single moment of our lives is virtually everything that we could ever want to know.
