So Adam's sin becomes an act of Love? And, for that, he is punished... and his children are condemned to punishment and death? God becomes very heartless indeed.
Another concept that I think people get is that somehow God punished Adam for trying to be more like God. Again, I don't think that squares with the true nature of God. Adam's sin was not an act of love; neither, was it an attempt to become more like his loving Father. No! Adam was not deceived! Neither was God unjust. Adam's sin was the ultimate act of rebellion! He was not trying to become more like God, but rather like "god" (Satan) ...and God's punishment was correct!
Genesis 3:4-5
And the serpent said unto the woman, Ye shall not surely die: [5] For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
I believe the rendering here is correct. Satan's offer was for Adam to join his side against God, and "be as gods." The confusion arises in this verse:
Genesis 3:22
And the Lord God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
"of us" is the question. The "of us" is added by the translators. "The man is become as one..." One what?... is the question; and according to verse 5, it was as "god (s)..." (small g). Now the punishment fits the crime.
