Is this a Material World?

Which reminds me of the John Lennon song, "Imagine." Imagine there is no heaven or hell. Below us only earth, above us only sky. You could concentrate really hard and imagine that this is only a "material world," to quote a Cyndi Lauper song, and still it would not be so. This "Imagine" joke I borrowed from a co-worker, Mindy, I must confess, so it is not really I who first thought this way. There are many who think that there is more to things than meets the eye. There are many who believe that there is a spiritual realm behind it all that cannot be reduced to molecular science. The heavens declare the glory of God, is how the Bible explains it.
