Why would you suppose God will say, “Yes, you are going to drink tea,” when he knows infallibly that you will refuse to drink it?
What he knows from eternity is precisely what you do at t=x, so why would he tell you that you actually will do what he knows infallibly that you won’t?
Reality is dependent upon God as the Creator and Sustainer of the universe. It isn’t that he just knows what will happen. What actually happens is dependent upon his knowing it. Reality or creation is akin to ideas in the mind of God, so what will happen is dependent upon his thinking of it.
You wouldn’t be able to outthink God because your thoughts and ideas don’t generate reality, but his do. What he thinks, will come to pass BECAUSE he thinks it.
Your concept of God is sorely lacking. You seem to think he is sort of like you but liable to be outsmarted by you because you are a little more devious, and perhaps you won’t blink at the wrong time to give away your intention. Unfortunately, that isn’t God you are describing. More like your little brother.
Put another way, you think that if you and God get into a mental sparring match, you will come out on top. I hate to break it to you, but the odds on favorite is God.
