I have scoliosis. My spine has a curve in it that makes the shape of the letter c. In eighth grade the doctor told me that it wasn’t likely that I would be able to have children. 

I have three. And I still have scoliosis.

God is capable of blessing His children in spite of the weakness of our physical bodies.
He is also capable of receiving glory because of it.

Paul had finally resigned himself to accepting the reality that his thorn in the flesh wasn’t going to go away. He chose to praise God because it had been revealed to him that God was using it to help other people. God was using Paul’s physical weakness to glorify Himself. 

No matter what you may be facing you can still glorify God. Because His grace is sufficient and His strength is made perfect in weakness.
