The fact is, it is not you, in isolation, that can heal. Of yourself you can do nothing. You do not have a special healing power and you are not a healer.
The fact is, God is the healer. God is love and love heals. And it is also not necessary for you to be in perfect alignment with God's will in order for healing to occur.
If we were required to be enlightened in order to facilitate healing, nobody would be able to receive healing and there'd be no hope for the sick.
The fact is, Holy Spirit has been given to us as the answer to the ego and to undo every aspect of the entire ego illusion. He is capable of functioning to heal us FROM the dream, even when we're in the dream, and even when we're still dreaming. If he did not have this ability, we'd never wake up.
Nor are you required to be free from all sin or ego thoughts. Nor do you need to have a perfect relationship with Christ.
All that God needs in order for a healing to take place, is for you to have enough belief that it is TRUE that God can heal, that God will heal, that God HAS healed, that God wants to heal, and that God IS healing.
And all you then need is enough acceptance of this to step out of the way and to act as a channel, medium, conduit or bridge through which God's healing can flow. That can take the form of you simply being open to RECEIVING and BELIEVING God's providence of healing, which you then are infused with and radiate, or it may come in the form of you laying on your physical hands to someone else, or by you using words which are spoken in a God-aligned way.
Since God's nature is absolute, not relative, God doesn't do things by half measures. God is certain. God is consistent. God is completion and wholeness. So if there are aspects of incompleteness or waiting for the future or uncertainty, in how you approach someone (ie forms of fear), that will block God's flow.
But if you take on an 'absolute' attitude which has no question in it, no uncertainty in it, and it is resolute and firm and truth-filled, you now are forming a bridge for God to flow across. This can come in the form of words which you speak, and these words really don't matter. As you speak, words are energy conduits which allow Holy Spirit to transfer.
And as you speak, you speak TO the problem, directly, and you tell it what to do. You don't talk about the problem. You don't ask God about the problem. You don't ask God to do something about the problem. God has already provided healing. It is your job now to extend it, to share it. And you don't ask the problem to go. You don't request that it go. You don't sidestep around it. You get VERY DIRECT. God is very direct. Immediate. Direct in terms of you directly confronting the exact thing (e.g. pain, sickness), and immediate in terms of time (ie this will be fully healed NOW).
You must expect the result to be immediate and complete, not partial or off in the future. You must also have an expectation that healing definitely will occur, that you could bet your life on it. Certainty. That you will walk away having commanded it to heal and it WILL be healed. And you can't waver from that or go into doubt based on how things appear to be. That's losing faith.
For example, you put your hand on someone, maybe in the area of sickness, and you COMMAND IT TO GO. You tell it what you want it to do. "pain, leave right now, GO!" "tooth, be whole, right now" "brain, return to normal functioning right now" etc.. You have to be firm and assertive. This is how God is. God knows what is true. God doesn't waver. God doesn't listen to the ego's illusions that try to distract you. You have AUTHORITY over the ego.
This takes some practice. It's good to experiment.
1) Join with Holy Spirit/Jesus/God. Feel love.
2) Place hand on person
3) Believe and expect total healing, not taking no for an answer
4) Command it to leave. Repeat if necessary.
5) Allow Holy Spirit to flow through you. You don't need to do anything else.
You can do this whether you're awake or not because this is what God has set up to be possible. It does take some amount of certainty and belief and conviction in God's truth, so the more you have of that the better, but you don't need to be an ascended master to get some results.
