Healing in the larger passage context more likely refers to the soul's restoration back to God, the removing of enmity. Healing of the broken hearted for instance is not so much a healing of the physical heart/arteries. Healing of the nations is not so much a physical healing of diseased people within those nations. Restoration (healing in this case) surely has more to do with proximity or position or good standing; the returning to the Bishop of our souls.
