I hesitate to make another post before markinark puts up a better reply to my previous posts, but this predestination page is too stupid to ignore.
I have tried to present a balanced examination of the issues regarding free will and predestination. It is obvious that the Bible teaches both concepts. Ultimately, I believe that God directs history. However, I do not believe that He micro-manages history. In other words, I think God places people in history so that His will is accomplished. This includes putting His followers, in addition to those who oppose Him, at strategic points in history. The Bible encourages us to use our free will to choose good over evil.
So yhwh tampers with the milestones but lets us get their on our own free will. The problem is the butterfly effect. There are so many choices available to so many people, the slightest wrong turn could throw it all irrevokably out of kilter.
Just look at yourself. For you to be who you are at this moment, it required an uncounted number of highly implausible events to occur. If yhwh had you in mind to start with, and said "I'll make sure his parents met and leave the rest to chance," he'd have been fucked. Yhwh would have need a specific sperm cell carrying the exact right combination of DNA (or is it RNA for sperm?) to meet with just the right egg. That means if your parents had successful copulation at any moment other than when they did, there would be no you. There would have been someone else. Heck, had your dad "gone off" one second sooner or one second later, there would be no you.
Or is the assumption there that yhwh micromanaged the DNA? Then that is as bad a no free will. That is the illusion that your choices matter, but they really don't, they lead to the same conclusions no matter what. We D&D nerds call this "railroading".
Let's assume this is what yhwh does with DNA. That still leaves the uncounted moments of your life's experiences, the little choices. That would literally require yhwh tipping the scale continually to ensure you end up exactly where you are now. The whole idea that yhwh meddles only a little is preposterous.
