There are as many interpretations as their are interpreters of this chapter in Ezekiel. Yet, I would humbly offer that it is a prophecy concerning an end times battle against Israel that has yet to be fulfilled. Nations from the North of Israel will attack Israel during a time of peace and God Himself will fight for Israel and defeat the armies of the North.
My comments are marked by the following principles of interpretation: 1) Scripture is divinely inspired, 2) Scripture should be interpreted as literally as the literary genre and context allow, 3) Scripture contains prophecies that have already been fulfilled as well as those yet to be fulfilled, and 4) the revelation of Scripture is progressive, so that later prophecies shed light on earlier ones.
Those who have a high view of Scripture see history heading towards an ultimate climatic victory of good over evil, Christ over Satan, and the judgment seat of God. The apostle John, like Ezekiel, had such a view of Scripture. He also prophesied of a future day when God would defeat Satan and the nations he deceived named, “Gog and Magog” (Rev. 20:7-9).
While certain details of this prophecy remain a mystery, such as the identity of “Gog and Magog” (Is it Russia as some contend?). The major predictions are clear. God revealed an end times war against Israel that God Himself will win. God will triumph in the end. Therefore, let us decide whom we will serve. Let us join Joshua in saying, “As for me and my house, we will serve the Lord” (Josh. 24:15).
