1. God chooses us to do right (1-10)
The LORD spoke judgment against the descendants of all those he graciously brought out of Egypt. He would punish them for their sins. The Israelites might have felt secure as God's chosen people. But just as various occurrences in the world all have a reason (3-6), God's judgement had a clear reason (7). God wanted his people to repent. Even pagan Ashdod and Egypt saw how the wealthy in Israel had plundered her own people.
2. Amos details impending disaster (11-15)
The LORD foretold that destruction would come from an enemy. The enemy would devour virtually everything. God would take away all that the Israelites trusted in, from their religious artifacts to their winter and summer homes. This was the result of their sins against God and against each other.
