Let's talk about free will.

67. "If God knows which decision I will make before I exist ..."

... If God knows which decision I will make before I exist to participate in said decision, then the decision has nothing to do with my choice or action. Therefore, it seems that genuine free will must limit God's knowledge to that which exists, with the results of free will choices deemed not to exist yet (this is commonly called "open theism" ). Furthermore, if my decision really is free, then it is under my control, not God's. But that means that I have some power that God does not, and God's power is accordingly limited.

Einstein's understanding of time is that there is not really such a thing as an isolated moment of time. He believed that all time existed simultaneously - ( link to source ):

Surprising as it may be to most non-scientists and even to some scientists, Albert Einstein concluded in his later years that the past, present, and future all exist simultaneously. In 1952, in his book Relativity, in discussing Minkowski's Space World interpretation of his theory of relativity, Einstein writes:

Since there exists in this four dimensional structure [space-time] no longer any sections which represent "now" objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical reality as a four dimensional existence, instead of, as hitherto, the evolution of a three dimensional existence.

Einstein's belief in an undivided solid reality was clear to him, so much so that he completely rejected the separation we experience as the moment of now. He believed there is no true division between past and future, there is rather a single existence. His most descriptive testimony to this faith came when his lifelong friend Besso died. Einstein wrote a letter to Besso's family, saying that although Besso had preceded him in death it was of no consequence, "...for us physicists believe the separation between past, present, and future is only an illusion, although a convincing one."

If Einstein's understanding of time is correct, an omniscient God - almost by definition having a God’s eye view across all of simultaneous time - knowing about your decisions before you’re aware of having made them - you living under the normal human time perspective - does not seem to cause any conflicts between free will and such a God’s powers.
