Our earliest indication of the conflict is recorded in the scriptures as the War in Heaven, meaning a war that was waged among the spirit children of God in the premortal life. It began, so far as we know, with the rebellion of Lucifer against God over a difference about how God’s spirit children, of whom Lucifer was one, could become like God (see Moses 4:1-4; Abr. 3:23-28; D&C 76:25-26).
