In this lesson Mushrooms or a Mighty Oak Tree, as leaders, we must be very careful to make sure that such wolves will not enter and destroy any of the flock of God. We must guard the truth! He did not want us to be spiritually immature, like children who are unstable and carried about by the winds of false doctrines.  We are growing up into oak trees and not mushrooms.  Winds will blow down mushroom churches but never the mighty oak.
