Home Is Where the Heart Is

I wonder sometimes how fundamentalists who claim to take every word of the Bible literally interpret non-biblical idioms. Does the sentiment “home is where the heart is” require anatomical correctness? Is there a difference between a house and a home? Such quirky questions may be quickly tossed aside, I’m guessing, because that specific phrase does not appear in Scripture and therefore God did not say it. Anyway, to embark upon the venture of “going home” does require some definition, and to say that it is “where the heart is” works for me. Alas, I’m not all that sure where my heart is.
