Alma 12:18

Then I say unto you, they shall be as though there had been no redemption made; for they cannot be redeemed according to God’s justice; and they cannot die, seeing there is no more corruption.

I tell you, it will be as if Jesus never saved them. God’s justice won’t let them be saved. They can’t die because their bodies won’t break down anymore.

For them, it’s as if there was no redemption at all. They can’t be saved—God’s justice won’t allow it. And they can’t die again, because there’s no more death.“
