Its also important to remember, for those of us who believe in Jesus (i hate the word Christianity), that when people came to Him for healing and were healed, He would tell them, "Your faith made you well". Now my prayers have changed lots. I normally ask for something once and after that i daily keep thanking God that its done and instead of begging, i claim His promises. Jesus said that The Father would give me whatever i asked for in His Name. John 15:16. why not? He won the victory. He never sinned even once while in His human body.
One promise that i stood by and got healed just from thanking God that it was done is Isaiah 53:5. Yes nothing happened for a long time; for almost 3 months i stood by that promise and finally the pain left my body because i refused to be moved by what i could see or feel.
