Some healing theology puts the burden on the person who is sick — believe hard enough, claim it, speak it into being. The biblical model is different. The people Jesus healed came to him in all kinds of states — desperate, doubtful, bold, silent. The woman who touched the hem of his garment didn’t ask out loud. Blind Bartimaeus shouted from the side of the road. A father said “if you can do anything.” All of them received something.
What they had in common was not the quality of their faith. It was that they brought themselves to Jesus with what they had. That is what this prayer does.
