He is the Great Physician.
We must learn to pray to a God who is active and able.
Every Christmas, the Portland Symphony Orchestra performs slews of concerts and involves a large community chorus in the program. Year after year, I watched a woman in the front row of the chorus. She had multiple sclerosis and it was evident she was worsening rapidly.
It was hard to watch. I saw her stand on crutches. The next year, a walker. Finally a wheel chair and eventually she was bent over in the wheelchair.
One day years and years ago, I got a call from one of the string players who said, "Have you heard about Joanne?" I said "Joanne who?" Then she told me it was the woman in chorus. The caller wanted me to know that Joanne had been completely healed and was walking normally.
I had to see it with my own eyes.
I did not know Joanne socially, but I looked up her phone number and called her. It was true. She had been healed. I had not even known she was a Christian. She had not been at any kind of healing service or any such thing, but was at a Christian dinner club when the pastor just came over to her while speaking on a topic. He put his hand on her and was simply speaking to the group.
Joanne was instantly healed and everyone was shocked. There was no expectation of it. The Lord just did it.
When I next saw Joanne, she stood straight and practically danced all the time. Of course she was thrilled. I still see her at the Christmas concerts and she is completely well
God chose to heal her and did not let us know the reason. He can and he does. At the same time, He often chooses not to heal the body.
We so often limit the Lord. I don't know why He heals some and not others, but I do know He can be trusted.
Trust is the real issue. If He does heal, it is the best thing. If He doesn't, it is the best thing.
Be clean and pray.
