First, thank you for your answer.
You are most welcome.
Second, I don't see the idea of a temporarly restriction to eat from the tree of knowledge of good and evil in the Bible but I have no problem with that interpretation. I have a problem with why was it bad for the first humans to do that, and why God got so infinitely offended as in to punish the entire Universe because of that, and all the future human generations? Didn't God made Adam and Eve? Didn't he made them with the way they were with this predisposition and attraction towards temptation? He did make them the way they were or do you disagree? And who planted that tree there? Who gave the commandment? Who had foreknowledge? Who is responsible for this? Don't worry I am expecting this to be complex, and I openly wait complex answers.
This is another begged question, though I acknowledge it is likely unintentional. Orthodox theology does not see the ramifications of the Fall being that God is infinitely offended and now must punish the entire universe. Rather, we see the ramifications of the Fall being consequences of a broken communion with the divine energies. So for us, it isn't a legalistic matter of offense and punishment, but an existential matter of cause and consequence. I like to use this analogy -- when my daughter was very young, her mother was baking in the kitchen. My daughter kept approaching the stove, and my wife kept telling her "stop -- it's hot, you'll burn yourself!" Yet in a second of inattention, my daughter grabbed an oven rack and badly burned her hand. Now, one could say that my child was punished for her disobedience, and that is in a sense true. But what one would not say is that my wife burned my daughter for disobeying her.
In the same way, we can rightly say that Adam and Eve, and as a result, all of mankind, has been punished with death due to Adam and Eve's disobedience. But we would not say that God has killed them. And note, in Genesis, God says "in the day you eat of it, you will surely die." He does NOT say "in the day you eat of it, I will kill you." In their disobedience, Adam and Eve suffered the consequences of being separated from God, a choice they made using their own free will. That does not mean that God caused the consequences, at least not in a sense of God being morally responsible for their choice.
If Christ fixed those things why are they still taking place? Things like corruption, sickness, sin, death and etc?Feel free to tie everything you want to your answer/s.
Because we are still subject to mortality in this life, and we have free will. The determinist position is that we do not really have free will, and our actions are determined. This is in line with Calvinism. For us, however, we actually have free will -- we can choose between competing actions. That free will in human persons is darkened in the fall, for reasons it would take too long to get into here (but please research the Orthodox concept of the gnomic will), but the natural will is still essentially free. That is why we still have evil and sin in the world -- because man, after the Fall, has a deliberative will that forces us to make choices. The use of the will is marred by this deliberative aspect, so we sometimes choose to sin because we are inwardly focused, narcissistic, vainglorious, etc. We think of ourselves first, and this is primarily due to mortality. It is a more animalistic condition than was intended by our Creator. In communion with Christ, we begin to break free of this in this life, as we live the Sacramental life and are brought into communion with the Holy Trinity. Our will is conformed to God's will. But this is a process, not an event, and so as we struggle, we grow. Much as someone learning to walk will stumble a lot when they are 1 year old, but when they are an adult, they stumble less (but still stumble nonetheless).
Corruption, sickness, death, etc. are still consequences of the Fall, but in that suffering and death, God now saves us. Rather than being in eternal separation from Him, He brings us into communion with Him through Christ. So while we suffer corruption, sickness and death, we are, through those things, also being healed.
