When the people proclaim that they have “great views of that which is to come,” the reference is to the atoning mission of the Messiah. Benjamin explicitly declared, in Mosiah 3:1, that “I have things to tell you concerning that which is to come.” He spoke of the mortal mission of the Messiah. The people are echoing that focus.
The important part of their unified verbal declaration is that they are “willing to enter into a covenant with our God to do his will.” This is an interesting concept of the descendants of Israel. There was a covenant in place. That covenant continued. What is suggested here is that there is a new covenant being instated. There is an explicit desire to redefine their community. Perhaps it only reinforces the Israelite covenant, but the nature of this covenant will focus not only on Jehovah as God, but Jehovah as the Messiah.
