Just a thought, but some have argued that God set Adam and Eve up to sin by putting that tree in the garden. Some have even argued that God is responsible for sin as result. But the devil sinned before the tree. Would Adam and Eve have sinned even without a tree, then? Satan did. That tree may have been grace in action- to sin by taking of that fruit, for God to have offered that possibility, perhaps offered a way to redemption… something Satan didn’t have. Personally I think just making us with a body and soul did that. But God didn’t make sin, didn’t make Adam and Eve sin, by putting that tree in the garden. There was already sin, evidenced in Lucifer’s fall.
Of course, still too there is the fact that from the beginning, God gave us freedom and choice. I just hadn’t considered that Satan had already fallen before. Just another facet of interest…
