Jesus has already done the healing. All your husband needs to do is, find a scripture that promises healing and
say it with a mustard seed of faith.
Then forget about the problem. From that moment on, just give God praise. Don't tell anybody about the problem, don't talk about the problem. Don't think on the problem. Just talk about the answer as if you have it now. Keep doing that until you see it come to pass. (
Mark 11:23-24)
