In purely technical terms, Alma is conflating the coming of the Atoning Messiah with the coming of the Triumphant Messiah. The final judgment of mankind does not occur until that final closing scene. Alma is correct, however, that even prior to that ultimate scene of judgment, the consequences of our life choices will be upon us. The mission of the Atoning Messiah is to provide the means of repentance whereby any life that sees the vision of the message of God may turn to him and turn away from the “power and captivation of the devil.”
