Wow, 16 pages of stuff I had to catch up on, heh.
Someone mentioned that if they foresaw that they'd get in a car crash on a certain day, that they could change their future by not getting into a car. What if not getting into a car is your real destiny?
And if God eliminates certain possibilities, does that eliminate free will--if slightly? Let's say, back in the day, I wanted to visit Sodom. I'm planning my trip, getting packed up, got my plane tickets in hand (Just bear with me lol), but God steps in and says "Wow, those guys are bad. I'm going to blow them up!" So, He eliminated my free will to go visit Sodom, yeah?
