This is true, but it is grossly misunderstood and misused by the ego.
In order for this truth to apply, you have to BE in your innocence. It can't be intellectual. You can't use it to justify murder.
You first have to get yourself into your innocence, so that your innocent isn't just an informational fact, it's an experiential fact. And in order to experience innocence, that places you in the mind and being of LOVE.
It is not possible to experience such innocence without aligning yourself with love.
Therefore, once you ARE aligned with love, you are in your innocence, and whatever you do WILL be innocent. Or to put it another way, no matter what you do, it WILL be loving - and it will never prove you are guilty.
It's only when you take this fact and try to apply it to life without the experience/alignment with its truth (truth is an experience not intellectual information!), that you distort it and then use to justify actions that you perform not based on love, such as that it is okay to hurt someone or "do bad things" etc.
When you do that, you have "level confusion". You've attempted to take something that it is a truth on a higher level of metaphysics, which can only be *experiential*, and are attempting to apply it to a level of existence that is not experiential, where there is separation between you and the truth. And that's why it turns into justification for war. And this is also why religions have led to more wars than most any other cause.
No matter what you do, you are innocent, free, forgiven, loved and loving. But if you're not truly authentically living from such a state of being, then beware your ego's misuse of it.
