2Ne Ch30

Good news! Gentiles who are converted will be numbered with the covenant people. Even Lamanites and Jews will become delightsome. It is predicted that Israel will be restored while the wicked destroyed. 

Nephi speaks concerning the righteousness of the Gentiles and how many will not be destroyed because they repent and follow the commandments (v1-2). After the Book of Mormon comes forth, many will believe it and carry it's words to the remnant of Nephi's seed so they get the chance to receive it (v3-5). They will realize their history and be gathered unto The Lord to be restored (v6-8).

The Lord will come and judge and cause a division among the people between the righteous and wicked (v9-11). Once the wicked are cast off, there will be peace between all creatures with full knowledge of all things (v12-15). There will be no secrets because there won't need to be and no darkness or kept sealed from us (v16-17). With all this knowledge of truth, satan will have no power over our hearts for a long time (v18).
