That's not the right way of doing it!
A few years back I was rehearsing, (to my friend and his wife), how I prayed for an unbeliever, for the Lord to heal her of a bad toothache and how I had to prayed three times before she got healed. These were two friends of mine and as I finish the story, the man's wife asked me if I would pray for her migraine headache, so I said yes I would. I laid my hands on her head and I prayed for the Lord to heal her from the headache. After I prayed, I asked her how she felt and her reply was, that she felt better, but she still had a headache. So I said, that's not what I prayed for. So I told her I would pray again, so I thanked the Lord for healing her and then I commanded Satan not to interfere with this woman's healing and commanded the pain to leave. I again asked the woman how she felt and again she said she felt better, but she still had a headache. As if this was a case of déjà vu, I said I would pray one last time and again I laid my hands on her, thanking The Lord for his healing and then I commanded the lying spirit to release her and for the pain to depart. As I began to ask her how she felt, her eyes opened real wide as if she was surprised or shocked. I asked her how she felt and her rely was all the pain completely left.
A few days later my friends came to visit me and right off the bat, the man's wife asked me if my prayers would work on any pain? I said to her, pain is pain, big or small it makes no difference to the Lord.
The woman the told me how she just recovered from having a miscarriage and now every month she goes through excruciating pain from her menstrual cycle; she was wondering if I could pray for her. I asked if she was in pain now and she said, "Yes, a lot of pain!" So I prayed for her and just like before, I had to pray three times for the pain to completely depart.
One month later, I get a phone call from my friend and he tells me his wife's menstrual cycle has started again and if I would come over and pray for his wife. I said I'd be right over. When I got there I could tell she was in a lot of pain, so again I prayed for her and again it took me three times praying for her, where then would I ask her how does she feel and she would say better, but it still hurt; where again each time I would say, "That's not what I prayed for!" After she was healed, I told them that they didn't need me to keep praying for them, that they could pray for themselves. My friend said yes I know, but my wife doesn't think my prayers work!
About two months later, my friend comes over to my house and says to me, "Man you have ruined my wife!" I asked how? He said you remember how you told us that story where you prayed for that woman and each time you asked how she felt; and then you would say that's not what you prayed for, so you would pray again. And how you prayed for my wife? I said, "Yes I do." He said, well now my wife is praying for all of the women at our Church and every time afterwards, she asks them how they feel? If they say they still feel some pain, then her response is, "That's not what I prayed for" and then she prays again. I had to laugh and then I asked him, "Well are they getting healed?" He said yes, but my Church doesn't believe you are supposed to pray more than once, if you're doing it in faith! "Man you have really ruined my wife!"
Sometimes I just have to shake my head at people and wonder, is this what Jesus went through, when he did his healings? (Not doing it as expected!)
