You might not be used to telling illusions what to do. You are more likely conditioned and used to a certain degree of victimhood, or powerlessness, which means that you allow stuff outside of you to seem to have power, or to have a say in what happens against your will.
Or to put it another way, you are used to listening to the ego. You're used to believing appearances. You're used to letting the world tell you what is happening. You're used to believing that these illusions are real and that they dictate what you are going to experience.
With divine healing, your attitude has to be different. It has to not listen to the ego. It has to not pay attention to appearance. It has to cut through all of the incoming signals from the ego illusion, ignore them completely, and demand and command the illusion to do what you want it to do.
So because of your mental conditioning in which you are very used to being quite wishy-washy about situations, where you sit on fences and maybe 'ask' life to change, you have to get out of that PASSIVE mentality. You have to stop paying so much attention to what your senses tell you and stop acting like a weak victim.
So this can actually take some practice to overcome and push past that conditioning, that way of using your mind that you've been so used to. It takes practice to learn whether you are actually fully COMMANDING that something change or be healed, versus whether there are elements of .. indecision, doubt, fear, uncertainty, paying attention to how things look, being caught up in the seeming reality of it, having reactions based on how the situation appears, etc... you have to weed all of that stuff out.
You need to become a finely tuned, PURIFIED, focused, clear, direct, certain, creative and firmly expressive miracle worker. You need to have authority. You must not lay down and just let the illusion, sickness, or whatever walk all over you with how much power it seems to have.
There is no order of difficulty in miracles, which means one miracle is not more difficult than another. But it ALSO means, MIRACLES ARE NOT DIFFICULT! Miracles are meant to be EFFORTLESS! In fact one of the miracle principles speaks of how miracles shouldn't be under conscious control, which speaks to how we need to be a conduit or bridge for the miracle to flow across without interference. But if our bridge is only half-built and stops short of fully extending into the illusion, to fully DELIVER God's promise of divine healing, then the effects will also fall short.
So experiment. Take time to speak TO the problem and tell it what you want it to do, explicitly and directly, not taking no for an answer. You have to be firm, and you have to be very clear. This takes some refinement. I've found that I tended at first to 'ask' problems to go. This does not work. I found that I would describe the problem. That doesn't work. I found that I would talk about the problem, to myself or others or to God. That doesn't work. I found that I would then talk about what I wanted to happen in a kind of future tense, but that also did not work. You have to tell the problem directly, NOW, in first-person immediate language, in a commanding way, "sickness, leave right now. Go! Get out!". You have to CONFRONT IT, which takes some balls especially if you are a people pleaser ;-)
I've found that it took several attempts and various failures to learn how to be commanding. It was not natural to me at first. I was too passive and uncertain and afraid. I would buy into doubts too much, like wondering if it would work or what would happen. We cannot be like that. We are representatives of God. We are like his policemen, enforcing his law. We have to be AUTHORITATIVE. And illusions MUST obey. But if you are not authoritative, illusions and sickness and all other forms of suffering will STAY because you are failing to give it a direct order to leave. If you don't use very direct commanding language, which is vague and wishy-washy, you will see 'reflected back' in the dream mirror vague results or half-hearted responses.
Illusions must respond to the commanding confidence of Christ.
In all cases, when Jesus healed the sick and so on, he always gave a very direct command. "Get up and walk". "Lazarus, get up and a live". etc... these are not requests. They are powerful commands. And that is how power flows across them. Words are a transit system for the communication and flow of God's power. You have to speak to the problem and tell it what to do.
"For truly I say to you, whoever SAYS to this mountain (notice the SPOKEN command), 'Be removed and be thrown into the sea!' and does not doubt in his heart (no fear, no uncertainty, completely belief and confidence), but BELIEVES that what he says will come to pass (believing it is a very important part of conviction), he will have whatever he says" (Bible, Mark 11:23).
