hmm, fwiw free will does not seem to be treated in the Bible, but if anyone is said to have that it would be humans, not Yah, Who is bound by...well, i would say the same things that bind nature or whatever, physics, even if they are written as "promises" in the Bible.

But this assumes Yah as a "person" from the outset, right? A faulty assumption, imo

"Changing the future" isn't changing the future because whatever happens is what the future will be, so it isn't changed.

If you want to show that God's impossible, there are plenty of ways that do work though. For a start, God can't know that there isn't another being more powerful than him hiding from sight but holding all the real levers of power, so he can't know that he is God, and that more powerful being can't know if he's the top monster in the chain either. Whatever magic he thinks he's using to know that there isn't a higher being, a higher being could be using a stronger magic to fool him into thinking he's the top one. (He's banned from using magic though in any case because he'd have to understand how it works, and as soon as he does that, it isn't magic any more, and that lack of magic renders him an ordinary being.) So, any being that thinks it's God is deluded.

Lets be honest, we don't know if a god exist, we don't know what it can or can't do.

The link is drivel, unworthy of the insult: syllogism with a false premise.

If you were raised Evangelical the free will argument was there to prove that god wanted you to choose him rather than him force you to do so. Nothing more, nothing less. Free will had nothing to do with ancients or philosophers. It was simply a choice your god gave you.

The problem of 'free will' has been 'discussed' by philosophers at least since the ancients.
