In the Bible I mean, or except at the beginning of a sentence or line of poetry. Jerusalem is, little Tekoa is, but not the dwelling place of God.
Who am I to try to figure this one out? Do I know better than the translators of the Bible? Of course not, yet I try.
Certainly, heaven is literal, as C.S, Lewis said, more literal, solid and real than where we dwell now. So that's not it.
Angels may fear to tread there, but here I go. When you think of all that you desire--like love, peace, joy, eternal life, everything good, true, sweet and desirable--they have no capital letters. Can it be that heaven is so great and large that we cannot confine it to mere "city limits"?
God has no such boundaries. Perhaps where He dwells has none either.
