Question: How can Hashem be all knowing and let us have free will? If the future is known to him, are we really making our own decisions?

Answer: This is an excellent, and complex, question. Let me add another question: Why, and how, can we exist? After all, G-d fills the entirety of existence with His presence, where is there room for anything else? The answer is that despite that, G-d created space within Himself in which man can exist on man-style terms. Therefore, although G-d, who is outside that box, does know and see all, as time is not a factor with him, within the box of creation, where we operate, there is a timeline within which we have free will.
