For generations, God had been trying to get the attention of the Israelites. However, they continued to disobey him. Most of Isaiah is God’s final warning and prophecy about the destruction of Jerusalem. In Chapter 40, the tone of the writing changes and begins to focus on the greatness of God and a reminder of His goodness. Regardless of Israel’s unfaithfulness, God will remain faithful and His greatness overshadows their mistakes and sinfulness.
