Do you know 『the three of knowlegde of good and evil』?

Adam who became a living being (Gn2:7) ate the fruit of the knowledge of good and evil that God told him if he are, he will surely die(Gn3). What is this tree of knowledge of good and evil and why was it made? What exactly is this tree that for the past 6,000 years until today the pastors did not know the true identity of this tree? The pastors and congregation members must know it’s true identity.

Inside Scriptures, there are many things hidden since of old, and what was hidden since the creation of the world, Jesus made it known by speaking them in parables (Mt 13:-34-35). At that time, the fulfillment was not spoken since it was not time yet. It was prophesied however, that when the time comes, everything will be plainly known (Jn 16:25).
