The Ramban’s conclusion is forceful and unmistakable:

When God is pleased with a person’s conduct, he has no need of physicians.

            The Ramban’s approach so disturbed Rav Chayim Soloveitchik that he was inclined to believe that the offending words were not the work of the Ramban at all, but rather an interpolation by a later copyist!
