Alma’s opening promise is that Shiblon would prosper in the land if he kept the commandments. Alma’s next address to Shiblon indicates that he has already been doing that, and that Alma has confidence that he will continue.
Textual: Alma uses the phrase “endure to the end.” This is certainly a phrase influence by the presence of that phrase in the Bible (see Matthew 10:22). The import of this phrase is persistence in following the path of the gospel. Our word in English also contains connotations of suffering that are not part of the New Testament meaning of the phrase, and not part of the meaning here. In this context it is precisely the concept of permanence in the way, as it follows Alma’s commendation of Shiblon’s steadiness and faithfulness. For more information on the meaning of enduring to the end, see the comments at following 2 Nephi 31:15.
