Alma 20

 I find it interesting what is written concerning the sons of Mosiah - 

"..when Ammon did meet them he was exceedingly sorrowful, for behold they were naked, and their skins were worn exceedingly because of being bound with strong cords. And they also had suffered hunger, thirst, and all kinds of afflictions; nevertheless they were patient in all their sufferings.

30 And, as it happened, it was their lot to have fallen into the hands of a more hardened and a more stiffnecked people; therefore they would not hearken unto their words, and they had cast them out, and had smitten them, and had driven them from house to house, and from place to place, even until they had arrived in the land of Middoni; and there they were taken and cast into prison, and bound with strong cords, and kept in prison for many days, and were delivered by Lamoni and Ammon."  (Alma 20:29–30)

The word "happened" suggests to me that the Lord allows agency and the actions of this world to evolve.
