God and the future

What follows is a more theological rambling than usual. While I don't normally get comments on my writings, this is something I am struggling to comprehend, so please, if you have a thought, pass it along.

The LORD saw it, and it displeased him

that there was no justice.

He saw that there was no one,

and was appalled that there was no one to intervene;

The Isaiah reading for Proper 25b brought forth the above passage in light of a conversation I had with a friend at seminary just the other day. This friend was laughing at the fact that he was considered by some to be a heretic, but those who called him such couldn't figure out what exactly about his theology was heretical. He shared with me two points that ususally lead to contention; 1) God does not know the future and 2) God exists within time. As we were walking to class at the time we didn't have much opportunity to flesh out what he meant by those two things, but we at least began to discuss point one.

His assumption that God does not know the future goes as follows. The future is not a thing. God does not know things that do not exist,for example, my twin brother George, since I have no twin brother. Therefore God does not know the future. I got him to admit two points; 1) God knows all possibilities of the future based on the freewill actions and decisions of human beings and 2) God is a pretty good guesser of what action humankind will take as he is vey much in tune with the human condition (see the Incarnation).

The passage I pulled from Isaiah seems to give some credence to my friends position. God is displeased by his people upon seeing their actions - he is not displeased prior. God is appalled that he can find no one to intervene - God must seek someone, He does not already know who will intercede. This has interesting ramifications on God the Son being made incarnate, i.e. was it the plan from before time? did God the Son have another option? does God even know when God the Son will return?

As will all theological suppositions this carries a ton of unintended consequences. If you see any please let me know. Also, I hope to discuss more about God existing within/outside of time witht this friend, but I think that may be where we find him to be "heretical".
