The book of Judges is not a great compliment to the spiritual state of Israel. Nehemiah wrote of this later, way later. He said, “Therefore, You delivered them into the hands of their enemies who oppressed them, and in the time of their trouble, when they cried out to You, You heard from heaven and according to Your abundant mercies, You gave them deliverers who saved them from the hands of their enemies. But after they had rest, they again did evil before You. And therefore, You left them in the hand of their enemies so that they had dominion over them. But yet, when they returned and cried out to You, You heard from heaven. And many times, you delivered them according to Your mercies.”
It’s not according to their deeds, it’s according to His mercies. We need to stop thinking that Israel has to be a perfect nation in order for God to fulfill His promises for them. This thought is not biblical. Now you’re probably going to say, “Yeah, but they have to believe in Jesus to get saved.” Sure they have to. But the plan of God for Israel, until the moment all of Israel will be saved, is a plan that has been already determined and neither the Amorites nor the Amalekites or even Hamas or the Ayatollahs can ever put an end to it. So you have to choose who do you support? On which side you want to be when you already know the end? You know the result.
