“It Was the More Righteous Part of the People Who Were Saved”

"Mormon seeks in these verses to impress upon [us] that it was because of their desire unto righteousness that the more righteous were saved. Those who were delivered from untimely death and also destruction, were 'they who received the prophets, and stoned them not; and it was they who had not shed the blood of the Saints.' Let us not forget that not only were the righteous among them, delivered from physical destruction, and their annals corroborate this fact, but they were all of that generation emancipated from sin. It is recorded of them, 'For none of them are lost.' The Savior's own words confirm this: 'And now, behold, My joy is great, even unto fulness, because of you, and also of this generation; yea, and even the Father rejoiceth, and also all the holy angels, because of you and this generation; for none of them are lost.' (3 Nephi 27:30)" (Reynolds and Sjodahl, Commentary on the Book of Mormon, vol. 7, p. 124)
