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 over a difference about how God’s spirit children, of whom Lucifer was one, could become like God. We do not know how long the war lasted, but we do know something of the contending armies and the issues … Fundamentally the differences were over (1) the principle of agency, which is always coupled with individual responsibility, and (2) the fact that godhood, with ultimate perfection, can be obtained only through individual effort and excellence. Jesus stood for the absolute necessity of these principles; Lucifer opposed them.
