Then the LORD God said, “Behold, the man has become like one of Us, knowing good and evil. And now, lest he reach out his hand and take also from the tree of life, and eat, and live forever...”.
There are two choices, you obey God and live in a perfect world as a part of creation and in essence also be a part of him. Or you try to be like him. The former is easier while the latter is a massive endeavour. The Magnum Opus, in the alchemical sense, of the entire human race. To BE like a god in knowledge but also in temperance, responsibility, power. Adam and Eve chose the latter and becoming like a god or angel is no easy task. God had created us to be as friends of a sort, by knowing of him you enter the great work.
