Free will

In the film "Bruce Almighty", God mentions that free will is something He would never mess with. He chooses to give people "choices" and let people make their own decisions. And, come to think of it, this is the biggest bane as well as the biggest gift to mankind. Bane - coz it often leads to so much of confusion in our lives that I am sure, no matter how good we are in decision making, we would be spending nearly half of our lives' time in deciding the "right" things (considering the variety of things we are "blessed" with) . Gift - coz, sometimes, we "feel" we have the power to control our lives, the power to believe in seemingly impossible tasks and come out of them, stronger and happier than what we were.

God is supposed to be our parent, who guides us in making the absolute right decisions in every phase of our lives. He is the one who gives us signs to do things in a certain way. Yet, it is not always that we get things right. Why? How do we know that we have actually followed a path that God indicated to us? Does He always guide us? And if He is wise enough to decide things for us in advance, why give us false illusions of "free will"?

The whole concept of "free will" and "destiny" is so mixed up in my mind right now, that I can't seem to put them together to make some logical meaning. If the concept of "destiny" is that "whatever will happen, will happen, no matter what" then the concept of "free will" seems to be contradicting it. Is "free will" just an illusion that God creates in our mind, coz He already knows our "destiny"?

Is God just another person who has enormous amount of work or, is He really some super natural who can actually do magic whenever He chooses to?
