5 We remember the fish, which we did eat in Egypt freely; the cucumbers, and the melons, and the leeks, and the onions, and the garlick:
6 But now our soul is dried away: there is nothing at all, beside this manna before our eyes.
This is a well-known scene from the Old Testament and it becomes in our modern times an example of not being happy with what you have, seeking luxury, being ungrateful, greedy and selfish.
Another pretty obvious parallel is the bread of heaven as a symbol for the bread of life. In the modern LDS church, I can see this case being made: Heavenly Father has revealed a certain amount of doctrine and gospel light to the people of the world and they have an obligation to daily partake of it and live according to its principles. These doctrines are made available through the scriptures and teachings of the prophets (i.e. the bread of life). If members of the church become bored with or tired of these teachings then they are obviously in the same error as the ancient Israelites. These Church members are unable to be happy with what they have, but vainly seek for more. Their selfishness is deplorable and in extension, they can be used as an example of sinful behavior. This can be used to denounce the people who enjoy speculation or scholarship or those who mention a desire for revelation on certain topics or those who seek to understand "the mysteries" mentioned throughout the scriptures.
I’m coming to this discussion late, but after just listening to Part 2, have to comment that the discussion on correlation is informing and validating some of my frustrations with the 72 ideas of the gospel. I’m feel pretty solid on those, to be honest. I got it down. I’m bored with the general instruction of correlation and like Andrew referred to I’m itching to move on to the “mysteries.” How I wish there was a post-correlation track for those who are ready to move beyond the basics and seek the “further light and knowledge” that is in the realm of pure speculation now? Sunstone is great for that, of course, but hardly mainstream in the church.
