You are the first person I've ever come across to say that a believer rejects that nature, the natural world (which is everything naturally occurring in the universe) wasn't created by god.
Where did I say that? You missed it when I said several times that everything is created by God.
Let me use the analogy of a role playing video game in a virtual world such as GTA. You'll understand this a lot better if you're a software developer/programmer. You design the video game. You have to write all that is possible and that can happen in the virtual world. You set the gravity, the size of the world, what a player can and cannot do, what the player looks like, what emotions they can feel, what is good, what is bad, etc. Now the players of the video game are all limited to what has been given to them however you as the software developer can do as you please in the virtual world as you can change gravity, the things in the world like shape, colour, texture, etc. anything. Players can lose lives, you have the power to give them life as many times as you want. You have no fear or worry in that virtual world as you can recreate everything in an instant. So if certain players decide to do evil and break the rules (which you have defined and told them about) what is the worst they can do? They can't do anything which is permanent since you have the power to reverse it or make it better than before. If those bad players decide to destroy a country which is populated by thousands of other players you can simply recreate that country in an instant.
The question then become more about how you want players to behave in your virtual world. If you tell them to behave and they refuse to do so you can either change their abilities so they can no longer destroy things, kick them out of the game, replace them, etc. Are you really concerned about them or the players which are behaving the way you want them to behave. Those that listen to you you may want to reward them. Those that go that extra step and actually do some difficult things just to please you you may want to give them an extra reward.
