This discussion is thought-provoking and highly enlightening. It is crucial to differentiate between the experiences of mankind in the garden and our own experiences. They were under different circumstances than we are currently. The test played a central role in the relationship between man and God in the garden, creating a tension. Despite having free will, man was also obligated in some manner. Redemption was not necessary at that point. On the other hand, we are born into sin and are incapable of any spiritual goodness on our own. Our obligation lies in turning to Christ, a task that can only be accomplished if God regenerates us, grants us a new heart, and works within us to have the will and ability to do so. They had a clear choice between trusting God and His knowledge or relying on their own understanding. They possessed the capability to choose not to eat from the forbidden tree. The cherubim and expulsion served as a demonstration of their failure in passing the test. By eating from the tree, they would have perpetually lived in sin. Whether they partook of the tree of life remains uncertain, although it is my belief that they did not. According to the book of Revelation, the tree of life is depicted as a reward for the overcomers. In my perspective, there is a danger in excessively linking their test with our redemption, as it leads to confusion regarding the biblical definition of a covenant. This understanding aligns with the exegesis of John Calvin, particularly in his writings on covenants. I would also recommend listening to John Murray's lectures on Calvin and the covenants, available on Sermonaudio.com. Lastly, could you please clarify what a "Calvin arm" refers to? These two concepts seem to be opposites.
