As for my thoughts:
Short answer: yeah, god knows what you're gonna do.
Long answer: To my understanding, god would know at any given point where you make a decision, any decision, that there are many, many, many possibilities. And at the very point in time where your decision is put into action, you are not necessarily deciding between which to eliminate and which to go for, but more that you decide which to make your current reality. The other options, the other choices are still made, you just simply do not choose to make those into the reality you wish to focus on. I'm thinking that the past present and future are much less linear and much more fluid than we are able to comprehend, allowing all choices to be fully experienced as other possible "you's". As other possible realities. (Reminds me of a Pink Floyd song that starts "They flutter behind you, your possible pasts")
As far as I am able to understand "God" isn't a separate part of "us", that instead it IS us, it IS reality, and thus, can't NOT know all of the possible realities that would exist in this way. And as all these other possibilities could be experienced, it is us who chooses which to focus on and REAL-ise. It is us who choose which to make present in THIS reality.
