>>508645882god announcing the future is god promising to make the future. the reference frame of omniscence as confidence in future sequence implies external forces ensuring confidence. Since god is the fully underlying force, this frame collapses to omniscence as omnipotence, and the free will/destiny outcome paradox collapses to intent and capability. If you ask god if he knows what you are going to do, you are also implicitly asking what to do- because you don't know what to do. And if he tells you that you will do a thing, and you do it because you were told you will have done it, then this is a self-fulfilling destiny.
The point is that god will help you to ensure you will achieve the things that he says you will do. That's a guarantee.
Secondly, there's a moral dualism inherent in a god that is expected to both protect you from harm and allow you to do whatever you want. Which is it? Free will or divine authority? by this construct it can be shown that these things are incompatible, you can't both expect absolute free will and also believe in divine power.
Lastly, there's the caveat of free will under zero knowledge priors. If you don't know what to do, then you dont have inputs to direct your choices anyway. In that respect you don't have a will to be free- you are just making random choices. If you do have inputs, you can only be truly confident in them if you believe them to be reliable. Since god is the most reliable input, his inputs determine your willful choices because you will ultimately choose according to the options he provides.
Free will is a misnomer, because it implies a stateless behavior within a stateful frame. Reshape your thinking. What you have is free agency- the power to make good or bad choices. Now you wonder why this is. Well, if you had perfect knowledge of all things, what point would there be in living life? what wonderful experiences can await someone with perfect foreknowledge? None. So you live free so that you will live.
