It never ceases to baffle me as to why it is Christians spout the phrase " free will" when ever they find themselves on the back foot of many religious arguments.
Ask a Christian why it was the biblical Adam chose to defy his god and his maker no less, and they simply throw at that one single phrase - free will - but never hang around long enough to explain what "free will" actually is in the biblical sense or when it was granted.
We get to Genesis 9 and god seems happy with his handy work, and his happiness is expressed again at Genesis 12 & again at 21,25 and up until god has one more look over his creation and it says at 31 "God saw all that he had made, and it was very good."
So we have humans created in the image of a god and god was very pleased and though all was "good" yet they both defy what god says. And no explanation as to why this happened. We hear that this pair of humans were somehow "beguiled" by a being known as the serpent. But if we backtrack just a few verses we can re-read that these humans were created in the image of god himself. and no mention whatsoever of them being granted anything resembling free will.. Or even a mention to them to beware of any being calling himself a reptile.
