God expresses in the Bible that people have free will. We simply don't have a clue as to how it works. And, the free will that we use every day, is artificial free will.
Proverbs 16:9 shows the way God and man are involved in mans' free will: "The heart of man plans his way, but the Lord establishes his steps."
For more passages that help to explain (or confuse), see https://www.openbible.info/topics/free_will.
we think we have a free will but in the end god has everything under controll, including the mess and the good parts of life.
Well, i think we're free to make decisions about or actions, there's that. It's just that every action we make of course corresponds to a certain consequence, whether it's good or bad for us. So free will is real. We're responsible for what happens to us and likely, for the people around us as well. Laws are there to be abided, and we're free to choose if we'll follow or not. Though again, there are consequences for our choices and actions.
