The free choice which Adam and Eve had was between believe God or believe Satan. They had no knowledge of good and evil. The issue is not choosing between good and evil, never has been. Adam had no knowledge of good and evil, but he was given the freedom to choose between believe God or don't believe God. This freedom of choice has never ceased. This is why God pleads all throughout Scripture for all to believe. Calvinist blind themselves to all of these pleas in favor of a flawed theology. For whatever reason?? We are specifically told why. Question is, why do you choose to whisk it under the rug? God certainly understood Adam could freely take of the tree of life and says so, thus He has to block Adam from doing so.
