You do need faith to be healed. I'm not the Healer. Jesus is the Healer. I can't guarantee that every person I lay hands on will be healed because I can't control whether they receive healing by believing. People need to do their part. I mean lets not make this out to be so simple. Some people don't know how to believe. I've been there myself. It certainly is God's will to heal everyone. Jesus took care of healing at the Cross. I mean if you don't believe that Jesus will heal you if you reach out to them, then you really need to start over. Because Jesus never said no to anyone, who asked Him to heal them. Again, to say the "Word of faith" movement is not biblical, is just plain ole foolishness. They read the same Bible you do and believe in the same Jesus you do. They just believe in verses that you don't. I mean lets be honest, you're part of a movement that still thinks that God cats lots up in Heaven to determine who He's going to heal. And you've pretty much made light of Jesus stripes and beating. The Cross purchased your healing, your prosperity, it made you the seed of Abraham and heir according to the Abrahamic blesings, it redeemed you from the Curse of the Law and it secured every blessing spoken of in Deut 28:1-14. Brother you are living WAY below your privilges as a son of God. My Abba tells me in His Book that I have a legal right to healing through the New Covenant. I don't need to know my Abba's mind about healing because He already revealed His thoughts on healing. Jesus took every one of our sicknesses and diseases. And we have the substance, through the Lord's Supper, of what the Israelites leaving Egypt only had a shadow of. Those dudes ate a roasted lamb and all left supernaturally healed the next day and left with silver and hold! We have the real McCoy in the eprfect Passover lamb in Jesus! Praise Jesus our Healer!
		
		
	 
Yes I agree Jesus is the healer, but that doesn't mean He has to heal everyone does it? Can he have a reason not to heal someone? Sure He can. Let's take a look at some Scripture.
John 9 "As he went along, he saw a man blind from birth. <sup class="versenum" id="en-NIV-26432">2</sup>His disciples asked him, "Rabbi, who sinned, this man or his parents, that he was born blind?"  <sup class="versenum" id="en-NIV-26433">3</sup>"Neither  this man nor his parents sinned," said Jesus, "but this happened so  that the work of God might be displayed in his life."
Here we can see one man who was born blind and Jesus said that the work of God might be manifest in his life. Now Jesus may not heal someone so that the work of God may be manifest in their life. Yes He did heal him, but it was for a purpose that you can read in the rest of the chapter.
Let's say a person is born who can't walk and they pray for healing. If they don't walk are we to tell them it's because they lack faith? You guys are saying yes that is true.
We are to have faith in God and the finished work of the Cross. Again if we look at the person who has not walked since birth, it is not because of a lack of faith they are not healed, it is because we live in a fallen world where sin still resides. Again God may not heal them so that the work of the Lord may be manifest in them. The problem is you do not know the mind of God and his reasons as I pointed out in Scripture.
Again God is sovereign and will do what He wants for His will and purpose. Sometimes a healing may not take place for His will and purpose. 
Romans 9:15-16 "For he says to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion. It does not, therefore, depend on man's desire or effort, but on God's mercy."
You mention it is God's will to heal everyone? No it is not, if that were the case everyone who is a true believer in Christ would be healed and they are not. It is not by a lack of faith, but by the will and work of God and His decision. 
You mentioned that I made light of Jesus' beating. I in no way shape or form did that, you only see it that way because I do not believe it is scriptural to say that by having faith we can be healed of anything, anytime we want, and when we want. 
We are to have faith in Christ and the Cross. We are to pray to our Lord and Savior Jesus Christ. We are to pray for His will in our life, and if that means not being healed for some purpose, then that is the choice of the Lord. As long as we pray for God's will then that is what matters, not what we think is right or what we want, because we don't have the answers, God does.
