One of the ladies in my Life Group had numbness and a tingling sensation in her arm for three years. One Sunday, during prayer time, she felt she needed to go out to be prayed for, so she did. After the prayer she felt it was slightly better, but in the evening she told me that the numbness has gone completely! To make the story a bit more interesting, apparently the lady who prayed for her told her that her Life Group had been praying specifically for the service for someone with an arm condition. God is still in the healing business even today.
