My scripture studies article on Moses 8 and Genesis 6-11 is here. Quote from the opening paragraphs:
“The great cataclysmic flood wherein “Noah…prepared an ark to the saving of his house” is one of the most well known stories in the Judeo-Christian world. It is story that most of us can remember from our youngest days. If needed, anyone of us could offer a simple synopsis of what occurred: God came to the prophet Noah, warned him of the impending flood, commanded him to build an ark and gather unto temporal salvation all living things into it. Noah obeyed. The mighty windows of heaven were opened and the great deluge commenced to destroy all flesh save it be what had been safely gathered into the ark. As soon as the flood ceased and dry land reappeared, Noah offered sacrifice of thanks unto God and God reestablished his covenant with Noah and his seed offering the sign of the rainbow as a token that such destruction will never come again among the children of men.
“But what is the purpose of this account? What doctrines or gospel principles does this scriptural account offer to us? What does any of this mean today, thousands of years after the fact? Our lesson today will look at each of these questions briefly, for it would be impossible to give an exhaustive treatment of any one of these questions.”
