It demands that we think what is, to many today, almost unthinkable: that when the Bible speaks of heaven and earth it is not talking about two localities related to each other within the same space-time continuum or about a nonphysical world contrasted with a physical one but about two different kinds of what we call space, two different kinds of what we call matter, and also quite possibly (though this does not necessarily follow from the other two) two different kinds of what we call time.
