Alma 9:6-10

Questions

Prophets in the Book of Mormon often begin their calls to repentance by reminding the people of what the Lord has done for their ancestors. (For example, Alma the Younger did this in his sermon in Alma 5.) Why? Were a modern prophet delivering a sermon like this, to what might he refer to remind us of what the Lord has done?

What are the people saying here? What do they mean by "Who is God"? Are they belittling Alma's teachings about God? Do they seem to be mocking a god that would only send one messenger?

What does Alma mean by calling the people a "wicked and perverse generation"?
How is Alma using the word "generation"?
What about this generation was so wicked and perverse?
Did the people forget the tradition of their fathers, or did the actively reject it?
What is the connection between the traditions of the fathers and the commandments? How might that connection be broken? In modern terms, how is it that this generation didn't get their own testimonies of the gospel? How were the traditions passed down? Were there weaknesses in how it was transmitted from one generation to the next?

What does it mean to be brought "by the hand of God"? Is this just metaphorical, or is there something else going on here?
Why does Alma switch from "our father" in the first question, to "they...all" in the second question?

What does Alma mean when he says the people have "forgotten so soon"? It has been decades since the earlier generations, their "fathers", were brought out of bondage?
What incidents is Alma referring to here, where the fathers were "delivered" and "preserved...from being destroyed by...their own brethren"?
Who are the "our fathers" referred to here? Does this include Mulekite ancestors, or just literal descendants of Nephi?
