I think that whoever came up with that saying was wise to include the word usually.
There are some people who, although they possess a well-worn
Bible, are still falling apart. (Please do not think that I am judging them; I myself came very close to falling apart years
ago during a time I will not blog about.)
Someone might have an old, worn, falling-apart, inherited Bible that stays on a shelf, unread. In fact, all the Bibles he or she owns go unread. Perhaps that person isn't actually falling apart,
but he or she is, in my opinion, missing out on a great deal of consolation and strengthening.
On the other hand, some people who constantly read the Bible are still falling apart; they see only the admonitions and the passages about sin, and Hell, and so they despair.
But much more often, thank God, a Bible that is falling apart does belong to someone who isn't.
I'll end this post by saying,"A Bible that is falling apart should be rebound."
