Isaiah: Book of The Conqueror | Isaiah 65
God speaks and tells the end of the story, which is the same as the beginning of the story, which is the same as the whole story: God saves people from their sin to enjoy real life only in Him.
Here's the climax to the Book of Isaiah: God speaks. Again. And Finally. The end of the story, God says, is the same as what the whole story has always been. God saves sinners to Himself. Now, this isn't just the end of Isaiah's story. The whole story-arc of the Book of Isaiah is a picture of the whole of God's story, the Gospel. So we see in Isaiah - creatively - that God's plan is to save sinners from their sin to enjoy real life only in Him.
