​ALREADY HEALED

If GOD'S HEALING is in the same ATONEMENT as FORGIVENESS OF SINS, then if we Pray and are not HEALED, how do we know our SINS ARE FORGIVEN? Our physical pain is not to destroy us; but everything is for the "SOUL PURPOSE" of our good (Exodus 15:26).   SIN CAN DESTROY US!  Scripture does not say, GOD IS OBLIGED TO HEAL, BUT IT IS BY HIS MERCY, BUT EVERYTHING IS FOR OUR GOOD.  Could it be that some of the MOST HOLY people are stricken with illnesses that require COMPLETE FAITH, just to complete the smallest of things that we all take for granted?  TO GOD AND THEM, THEY ARE ALREADY HEALED.
