What does Judges 6:9 mean?
Israel has cried out to the Lord to save them from the oppression of the Midianites (Judges 6:1–7). Before sending another deliverer, however, the Lord has sent a prophet to deliver a message to His people (Judges 6:8). The Lord wants to remind them of all He has done for them in the past. Forgetting the importance of these events is what led Israel to fail in their conquest of the Promised Land (Deuteronomy 20:16–18). It's also what led them to their current subjugation under foreign enemies.God's reminder included how He rescued them from Egypt (Exodus 12:51). He is the one who freed them from abusive slavery in Egypt. Through powerful miracles (Exodus 3:20), God delivered them from the Egyptians. He also led them into Canaan and gave them victory over the wicked people there (Judges 1:1–4). God had also been the One who freed Israel from her earlier oppressions (Judges 2:11–19). He is the one ever and always responsible for moving them from oppression to freedom, from slavery to independence, from suffering to salvation.
Even more than that, the Lord reminds His people that He drove out the nations before them and gave them the land He had promised. They took from nations under God's judgment exactly what God had always intended for them. The implication is this: God has been good to the Israelites by using His unlimited power for their benefit (Deuteronomy 7:1–5; 9:4–5).
The people of Israel may not have forgotten the stories, but they have failed to be faithful to the God who provides and saves.
