Another parable of the vineyard is in D&C 101:43-62. Verse 43 unlocks the purpose of the parable. The tower is the temple. The parable is referring to the Saints driven out of Missouri.
Isaiah 5:2
I like how, after claiming his territory (his goals), the first thing he did was remove the stones, taking out the things that would prevent growth of the fruit.
Isaiah 5:4
By all natural laws, the vineyard should have thrived.
Isaiah 5:8
The wicked are consolidating their power and resources, so that only a few may rule, "that they may be placed alone."
Isaiah 5:10
Their land will bring forth fruit in its season, also, socially, there are few spiritual.
Isaiah 5:12
We are flooded with entertainment in our day.
Isaiah 5:12,13
Even though they are eating and drinking a lot, they are hungry and thirsty, because they have no knowledge.
Isaiah 5:18,19
More social issues, they popularize sin. They mock God and seek for signs.
There's a pattern in the scriptures: the Lord will follow the bad stuff with promises of good.
