This chapter should be titled “The Faithfulness of God” because look at how many times the people disobey yet God remains faithful. I count at least 4 or 5 times in the story when the Jews disobey God yet each and every time He restores them when they cry out to Him. We see the same thing on a smaller scale in our own lives. We’ll go through life in cycles of disobedience to crying out for His help. Right now the Jewish nation as a whole is in a period of crying out for God’s mercy. This is a very unique time because it seems that there is genuine repentance and revival throughout the entire Jewish nation.
This one chapter gives us an entire summary of what God has done since the beginning of time. I think that this is a very important exercise because it helps you understand where you are in that plan as well as what God is doing at that time. If you cannot summarize what God has done from the beginning in Genesis up to today, then you may want to look into it. It will also help you get a better grasp on where God is going and might provide some clarity into the end times.
One last interesting note: in the ancient Greek texts it credits Ezra as dictating this prayer in verse 9:6. This is not present in the Hebrew texts, which are older.
