There is a very fine line between accepting this world and justifying it.
If I am having sickness, or problems, or negative ego thoughts, then something is wrong. It does not matter whether I am accepting these things or not, or whether I'm trying to be at peace in spite of them or not. If these things are happening, something is not right.
There is a significant group of people in ACIM circles who attempt to become "at peace with" everything that happens here. This includes being at peace with sickness, being at peace with death, being at peace with negative thoughts, being at peace with problems and limitations, etc.
There is something to be said for this because, on the one hand, if I resist or block or control or read-into or project onto or manipulate or become attached to something in the world, I am in the ego for sure. When events happen, if I resist them and don't welcome them, I will fight with them. That's not good. If I cannot allow someone the free will to choose whatever they want to experience, even if that means suffering and death, then I will not allow myself the same freedom of will either.
But... and this is a big but, that does not mean, that the goal of the course is to "be okay with" all of these things, to keep these problems, to maintain sickness, to promote peaceful death, or to continue having attack thoughts that we're "not bothered by".
Yes, I am supposed to let go of the world, let go of controlling it, let go of trying to stop people's choices, let go of not allowing etc. That's all good. But when that is equated with.... well, this means that I should not do anything about the world other than transcend it, then this becomes a problem.
Because now I am going to attempt to keep experiencing ego stuff while pretending that I am not. That's actually an act of denial. If I'm still having sickness in the body, something is wrong in my mind. If I am still dying, something is wrong in my mind. If I am still having problems and limitations, something is wrong in my mind. And if I am still having negative ego thoughts or body identified thoughts, there is still something wrong in my mind.
It is not our task to sort of ... get underneath our negative thoughts, or to .... go in back of our ego judgements.... etc. We are not supposed to be becoming "okay" with problems and sickness and death. In a sense we are... we are not meant to be upset by it, but we are not meant to make it real and we're also not meant to choose it. Choosing sickness is an attack. Choosing death is an attack.
So on the one hand, we're to become "at peace with" whatever happens, but at the same time, that peace MUST include not choosing to make bad stuff happen, otherwise we are intellectualizing the truth.
A mind which is in a state of love does not have attack thoughts. A mind in a state of love does not have a sick body. A mind in a state of love does not go through death. A mind in a state of love does not have problems and limitations. A mind in a state of love does not need to a find a way to be "okay with" intolerable bullshit. It may well BE "okay" with it in a sense, but at the same time, it does not choose it, manifest it, create it, maintain it, or make it a reality.
Exactly who is making the body sick when the mind is awake? Who is responsible for that? You are. And if you are, you are not awake.
Exactly who is making attack thoughts show up in the mind, which you are happily trying to transcend and allow to continue happening? Who is thinking them? You are. If you are having attack thoughts you have an ego.
Exactly who is making the body go through death? Who is bringing about the extreme victimhood conditions which are *required* in order for death to take place? You are. If you are dying, you have an ego.
We have to take total responsibility for everything we are experiencing and expressing and causing to happen, including the undoing of all sickness, death, suffering, and ego thoughts. Only the thoughts I think with God - loving thoughts - are real. All the rest is ego and it must go, otherwise I'm hiding in a corner and thinking hate while pretending to think love.
