William Boekestein writes:
There was once a powerful Syrian general named Naaman who had contracted the dreaded disease of leprosy. At God’s instruction, the prophet Elisha promised Naaman healing if he would wash in the Jordan River seven times. Naaman was indignant. Dipping in the Jordan was too undignified an act for him, and it didn’t fit his definition of help. If not for the persistence of his servants, he would have returned to Syria unhealed (2 Kings 5:1–14).
For the same reason, many people miss God’s simple, ordinary plan for their spiritual growth—diligent attendance to the means of grace.
