Many illnesses have as a lurking cause, unforgiveness. One cause of Rheumatoid arthritis may be unforgiveness. I knew a lady that had a very cruel husband. When he got Alzheimers, she developed rheumatoid arthritis. I heard about this and began praying for her. I asked the Lord to put someone in her life that would tell her about forgiveness and its link to rheumatoid arthritis. One day I overheard someone talk about this lady, that her hands were healed of rheumatoid arthritis. I asked, what happened? And I was told that on one of her many visits to the doctor, it came out about her husband's behavior toward her. Her doctor told her, "you know, unforgiveness is a cause of rheumatoid arthritis. She was a Catholic and she immediately stopped at the Church and prayed before the Blessed Sacrament, asking God to help her forgive - and her hands were healed.
