2 Nephi 2:25; “Adam fell that men might be; and men are, that they might have joy.”

2 Timothy 4:3-4; “For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; 4 And they shall turn away their ears from the truth, and shall be turned unto fables.”

Again, we see the truth.  This teaching is dualism.
