1 Nephi 15:33

1830 Edition

wherefore, if they should die in their wickedness, they must be cast off; also as to the things which are spiritual, which are pertaining to righteousness; wherefore, they must be brought to stand before God, to be judged of their works; and if their works have been filthiness, they must needs be filthy; and if they be filthy, it must needs be that they cannot dwell in the kingdom of God; if so, The kingdom of God must be filthy also.

Simple English

So if they die in their wickedness, they must be thrown out. This also applies to spiritual things that have to do with righteousness. So they must stand before God to be judged for their actions. If their actions have been filthy, they must be filthy. If they are filthy, they cannot live in God’s kingdom. If they could, then God’s kingdom would be filthy too.“

Paraphrase

“If people die in their wickedness, they’ll be cut off from spiritual things. They’ll stand before God to be judged. If their actions were filthy, they themselves must be filthy. And if they’re filthy, they can’t live in God’s kingdom—otherwise God’s kingdom would be filthy too.”
