Genesis 3:22 Then the Lord God said, \"Behold, the man has become like one of Us, to know good and evil. And now, lest he put out his hand and take also of the tree of life, and eat, and live forever\" This is where our free will comes from... Somebody mentioned earlier that sin s our free will. The knowledge of good and evil is what allows us to sin and ultimately have free will to make decissions.
