The pattern should be pretty clear now for those who have been faithfully reading through the prophets. God offers his people life and they turn away from him. He begs them to return. They do not. He brings calamity upon them as judgment for their sin and as a tool to determine all those whose hearts are truly his. Chapter 7 and 8 describe the judgment that comes even thougth scoffers tell Amos to go back to Judah and prophecy there. He tells them clearly what the Lord had told him–Go to Israel.
True to the pattern, however, the final chapter describes God’s faithfulness in keeping his promises. For the remanant (9:8 he will not totally destroy) there is a glorious future. The “tent” of David will be restored. There land will yield abundant fruit again (vs. 13) and they will live lives of great abundance.
And the key word is in verse 15 of chapter 9…Isreal will be planted and NEVER again be uprooted. This is God’s plan from the beginning of time–to live with his people in perfect harmony and for his people to enjoy him forever and ever.
