So are you saying that things happen in this world that are not in harmony with the will of God? Wow.
Consider God before the world ever began choosing all His actions, knowing all the actions and reactions of men. After all, James said that known unto God are all His works from the beginning of the world. The only way this is possible is if God knew everything, including what I was going to do, chose what He would or would not do as a result, and thus everything is in harmony with His will. He either chose to allow me to do something or to keep me from doing something. For instance, He chose to allow Assyria to conquer the Northern Kingdom of Israel. He chose to prevent them from doing the same to Judah. He chose these actions before the world began. They were in accordance with His will. One He allowed to happen, the other He was causitive in not happening. Either way, it was not outside of His will. Nothing is.
Now, the other issue is this: you say that God isn't allowing unregenerate man to do something. You have a fundamental misunderstanding of what it means to be unregenerate. It's not a case of God keeping an unregenerate from doing something, it is a case of the nature of the unregenerate keeping him from doing something. The unregenerate is not going to do good. The unregenerate is going to follow the course of this world, the prince of the power of the hour. He is going to live in the lusts of his flesh, fullfilling the desires of his flesh and his mind. He is going to be selfish, sinful, and will not seek God, love God, come to God, submit to God, etc. The scriptures are clear on unregenerate man. They that are in the flesh (unregenerate men) cannot please God.
