Discourses of Brigham Young, pg. 1; “The principles of truth and goodness, and of eternal lives and the power of God are from eternity to eternity. The principle of falsehood and wickedness, the power of the Devil and the power of death are also from eternity to eternity. These two powers have ever existed and always will exist in all the eternities that are yet to come. 11:234.”
Ephesians 2:15-16; “Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; 16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby.”
This is a lie, lie, lie. Satan’s power is not eternal.
