If you believe God isn't sovereign or completely in control of all things than you're basically an athiest. Because without his sovereignty and power there can be no God and atheists finally have indisputable proof that God doesnt exist.
You are saying that if God doesn't control everything he isn't God, because God is defined as someone who controls everything.
Biblical statements about God's power do not say that he controls everything. They say that he can control anything he wants to. You can just as easily find statements that God is surprised or changes his mind. As a result of this, there are various ideas about how God interacts with human choice. You can reasonably prefer some of these over others, but it's silly to say that if someone doesn't agree with you, they are an atheist. This posting borders on hysteria in its tone, and is unlikely to convince anyone.
In reality, if we look at what Scripture as a whole says, it says that God is powerful, that he has plans which will not be thwarted, and that we are only saved through his initiative, so we can't consider it our accomplishment. It also says that we are responsible, and speaks of him as responding to our decisions.
Traditional Reformed theology maintains divine control, and uses compatibilism to retain real human choice and responsibility. Unlike many, I think compatibilism is logically sound, even though many find it hard to grasp.
Arminianism says both God and humans have an essential role in human decisions.
Open theism and similar movements say that God does not fully determine events, either because he can't, or because he has intentionally limited his actions in order to provide room for human responsibility.
All of these approaches attempt to do justice to the range of statements we find in Scripture about God.
As far as things other than human decisions, one traditional viewpoint is that God does everything for a reason. This tends to turn into looking at everyday happenings as reward or punishments from God, although those are certainly not the only reasons God might do something. An alternative would be to see God's power in the ability to bring good out of evil, an enterprise in which he has given us a key role. Scripture sees God at work in many ways, but I believe it falls short of saying that he controls everything.
