3 Nephi 4:30-33, 5:1-3 – The Nephites Rejoice and Believe
30 And they did rejoice and cry again with one voice, saying: May the God of Abraham, and the God of Isaac, and the God of Jacob, protect this people in righteousness, so long as they shall call on the name of their God for protection.
31 And it came to pass that they did break forth, all as one, in singing, and praising their God for the great thing which he had done for them, in preserving them from falling into the hands of their enemies.
32 Yea, they did cry: Hosanna to the Most High God. And they did cry: Blessed be the name of the Lord God Almighty, the Most High God.
33 And their hearts were swollen with joy, unto the gushing out of many tears, because of the great goodness of God in delivering them out of the hands of their enemies; and they knew it was because of their repentance and their humility that they had been delivered from an everlasting destruction.
1 And now behold, there was not a living soul among all the people of the Nephites who did doubt in the least the words of all the holy prophets who had spoken; for they knew that it must needs be that they must be fulfilled.
2 And they knew that it must be expedient that Christ had come, because of the many signs which had been given, according to the words of the prophets; and because of the things which had come to pass already they knew that it must needs be that all things should come to pass according to that which had been spoken.
3 Therefore they did forsake all their sins, and their abominations, and their whoredoms, and did serve God with all diligence day and night.
