Isaiah prophesied that God needed a “highway” on which to travel into this world. That highway would be the Messiah, God in human flesh. Isaiah said that the Christ would be the perfect expression of the Spirit of God. When Jesus described His ministry, He quoted Isaiah’s prophesy. He came to bring good news to the afflicted and healing to the brokenhearted; to proclaim liberty to captives, and declare the time of the Lord’s favor had come.
