Adam & Eve didn't know that when they ate of the fruit of the Tree of the Knowledge of Good & Evil when they were told by the Serpent that "you will be like God knowing Good & Evil" Gen. 3:5 that the "god" he was referring to was himself, and would now be leading them & expressing his nature of (self seeking) good & evil thru their thoughts, actions, & words rather than their Creator.

Jesus understood this when He said, "A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. So then, you will know them by their fruits" Matt. 7:18-20

Only by Divine Intervention of cutting a man (who Jesus referred to as a branch Jn 15:5) from that tree can he be grafted into the Tree of Life. And therefore, on the RIGHT path.
