Isaiah 8 describes a spiritual darkness... then Isaiah 9 says a light is coming! The prophecy describes God's people abandoning God, and His mercy resting on outcasts: the Gentiles. When His Son comes, He is one with the Father, and Prince of Peace. Eventually His Kingdom will bring justice and righteousness until it takes over the world, through the passion God has for His children! His jealousy for us moves Him to expand His kingdom.
