Consider the Text at Romans 8:29
The text says "he also..."
Not "He therefore..."
This teaches us that God does not predestine things that he has to use his foreknowledge to see happen that way anyway....
"also".....
Not "later on".....Not "Because of"
The predestination of God is not dependent on how things happen anyway without Him...
In other words, God does not need to see how things end before he can predetermine how they will end....
A god who did that would be fake.
