During a large war between the Nephites and Lamanites, many souls departed from mortal life. In the context of these events, Mormon (the prophet-historian who abridged the Nephite record that was translated as the Book of Mormon), teaches about the great spiritual variance that exists when souls pass through the veil into the eternities.
“…Many thousand are mourning for the loss of their kindred, because they have reason to fear, according to the promises of the Lord, that they are consigned to a state of endless wo. While many thousands of others truly mourn for the loss of their kindred, yet they rejoice and exult in the hope, and even know, according to the promises of the Lord, that they are raised to dwell at the right hand of God, in a state of never-ending happiness. And thus we see how great the inequality of man is because of sin and transgression, and the power of the devil, which comes by the cunning plans which he hath devised to ensnare the hearts of men.” (Alma 28:11-13)
-What is Paradise?
-What is Spirit Prison?
-Will those who never had God’s law in mortality be led to Paradise if they choose to follow Christ in the afterlife?
