Chuck Smith discusses the prophecy in Ezekiel 39:27, emphasizing the significance of God's promise to pour out His Spirit on Israel after their regathering as a nation, which was fulfilled in 1948. He highlights the historical context of Israel's struggles, including the Holocaust and the Yom Kippur War, which shifted the nation's perception of God's involvement in their fate. Smith explains that the destruction of the invading army will lead to a recognition of God among the Jewish people, fulfilling the prophecy that they will know Him as their Lord. He also connects this prophecy to the broader timeline of God's plan for Israel, including the coming of the Messiah and the eventual return of Christ. The sermon concludes with a reminder of the church's role in God's current work through His Spirit.
