separation of good & evil

 In the Doctrine and Covenants, the righteous and wicked will be separated in the day of the coming of the Son of Man. The wicked will be cast into fire, while the righteous

will come forth in the resurrection: 

• Doctrine and Covenants 63:54: "At that hour cometh an entire separation of the righteous and the wicked" 
• Doctrine and Covenants 76:17: "They who have done good [will come forth] in the resurrection of the just; and they who have done evil [will come forth] in the resurrection of the unjust" 

The Doctrine and Covenants also describes the "days of wickedness and vengeance". These times are marked by: 

• Great human wickedness
• The wicked rejecting the Gospel of Jesus Christ
• The Lord punishing the wicked and destroying them from the earth
