You have much to learn about divine healing.
When healing happens, ultimately God always performs every healing. But the scriptures say the man healed them, God healed them, or the sick person’s faith healed them.
Acts 28
8 And it came to pass, that the father of Publius lay sick of a fever and of a bloody flux: to whom Paul entered in, and prayed, and laid his hands on him, and healed him.
9 So when this was done, others also, which had diseases in the island, came, and were healed:
Mark 5
34 And he said unto her, Daughter, thy faith hath made thee whole; go in peace, and be whole of thy plague.
