Even though I've used the title for Let It Go, you may think it may say that in the scriptures, but I couldn't another scripture reference that says "Let It Go" in it.
Here's the reference that I'm putting on here. I hope that you understand it better and think that you can find movies that are related to the scriptures.
Mosiah 10: 12-18
"12. They were a wild, and ferocious, and a blood-thirsty people, believing in the tradition of their fathers, which is this—Believing that they were driven out of the land of Jerusalem because of the iniquities of their fathers, and that they were wronged in the wilderness by their brethren, and they were also wronged while crossing the sea;
13 And again, that they were wronged while in the land of their first inheritance, after they had crossed the sea, and all this because that Nephi was more faithful in keeping the commandments of the Lord—therefore he was favored of the Lord, for the Lord heard his prayers and answered them, and he took the lead of their journey in the wilderness.
14 And his brethren were wroth with him because they understood not the dealings of the Lord; they were also wroth with him upon the waters because they hardened their hearts against the Lord.
15 And again, they were wroth with him when they had arrived in the promised land, because they said that he had taken the ruling of the people out of their hands; and they sought to kill him.
16 And again, they were wroth with him because he departed into the wilderness as the Lord had commanded him, and took the records which were engraven on the plates of brass, for they said that he robbed them.
17 And thus they have taught their children that they should hate them, and that they should murder them, and that they should rob and plunder them, and do all they could to destroy them; therefore they have an eternal hatred towards the children of Nephi.
18 For this very cause has king Laman, by his cunning, and lying craftiness, and his fair promises, deceived me, that I have brought this my people up into this land, that they may destroy them; yea, and we have suffered these many years in the land."
If you think about it, The Children of Nephi is like the people of Arendelle and that King Laman is like Prince Hans. It does make sense if you have critical thinking skills. If you understand it, then that makes it sound like you know what it's teaching you from the movie to the scriptures.
