Paul had a thorn. He called it "a messenger of Satan" — something physical that caused him real suffering, something he prayed about three times with enough intensity to ask God to remove it. God didn't. Instead, God said: "My grace is sufficient for thee: for my strength is made perfect in weakness." This is the defining New Testament text on disability and limitation, and it does something uncomfortable. It holds both realities — the reality of real physical struggle and the reality of God's real sufficiency — without canceling either one.
The Charismatic tradition sometimes creates a false binary: either you are healed, or your faith is insufficient. But Paul, who wrote about signs and wonders, who healed others, who moved in the Spirit constantly — he was not healed of his thorn. The apostle who perhaps carried more spiritual authority than any other figure in the early church walked with an unresolved limitation. That is Scripture's testimony, and it should quiet the voices that reduce disability to a faith deficiency.
The theology of the body in Scripture is also more complex than the prosperity gospel allows. Jacob walked with a limp after wrestling God — and God had just given him a new name and a new destiny. The limp was the mark of the encounter, not evidence that it hadn't happened. Some limitations are not obstacles to God's purposes. Some of them are signs of the most significant moments in a person's story.
