In that case we are not qualified to make true statements about reality. Don't you see how this position is self defeating? We as humans can only make true statements about what we perceive (even if what we perceive is not real it is true that we perceive it) so if what we perceive is not real then we have no way of determining what is objectively true or false.
So your goal is to determine objectively what is true or false. That seems to be your ultimate goal. Well, that isn't the point of my faith. We Orthodox acknowledge what we call mysteries. Mysteries are not things to be solved, as people tend to think of a mystery in the west, but things to experience.
But you are wrong, the position is not self defeating. Because you can make several true statements about reality.
For example, I perceive reality as I experience it is not reality as it truly is. What does that mean? It means that I am objectively wrong, but that God, reality as it truly is, is right.
And what do I claim? That The Ultimate Reality is God, and this is more true than any sense I can make of anything.
Now I really must insist that you answer these questions.
What sins? What evil? Forgiven by whom? Repent of What?
Sin is to fall short, to miss the mark.
It is evil to intentionally sin when you know it is wrong.
God forgives those who repent, or turn away from doing things they know are wrong.
So if you are in error, and you become aware of it, stop making the error. Turn around, don't do it any more. That is what it means to repent.
But if you really want to know this. stuff, I would suggest you go to an Orthodox Priest. It is their job to answer these kind of questions.
