1. God is great (31:30-32:6)
What is the content of Moses' song? Look at verses 1 and 2. The words of God are like showers on new grass, like abundant rain on tender plants. However, the people of Israel abandoned the righteous way of God and committed evil before God. God sighed, saying, "Is this the way you repay the Lord, O foolish and unwise people?"
2. Remember what God had done (7-14)
The best remedy for their ingratitude is to remember what God had done, when they were helpless sheep. He guarded them as the apple of his eye and the Lord alone led them to the path of life (12).
3. God's judgment on Israel (15-25)
Jeshurun was a nickname for Israel, meaning 'a righteous one'. Yet when they were filled with food and satisfied, they thought God was annoying them. God's judgment on perverse people will be fierce. Our real crisis is not the time of affliction, but the time of success and prosperity.
