I think when we get to heaven, it will be familiar; surprisingly familiar, but unbelievably better than we could ever imagine.
This world is not reality. It is a shadow cast by the Real thing. It is an outline or a form. "Now we see but a poor reflection as in a mirror, then we shall see face to face. Now I know in part; then I shall know fully even as I am fully known." This world is an impression, much like a fingerprint. It is evidence that something greater exists.
The things in this world that are good, like breathtaking scenery, laughter, food, soul-stirring music, sex, friendship, love...their origins are in heaven. They are reflections of the original; simple tastes of heaven that whet our appetites for the Feast that awaits us there.
What is it that we are experiencing when we are affected by beauty? When we wish a time of laughter and fellowship with friends wouldn't have to end? When we feel a soul connection with our mate, or when a beautiful song moves us to tears?
They are glimpses of heaven. They are reminders of our hunger; our longing to be filled, to be loved, to be happy. They are echoes of a Voice that is calling us home. Oh to turn our eyes and ears to heaven...and smile, knowing that is reality; that is where our hearts belong.
