The New Testament quotes Isaiah more than any other book and mentions his name twenty-one times. The Lord Jesus and the early disciples all knew this book well and shared the good news from it. But for many of us, its sixty-six chapters and various prophecies are overwhelming. We begin to feel lost as we read, not knowing who or what it is talking about. The Ethiopian eunuch was also confused as he pondered over Isaiah 53 (see Acts 8:26-39). When Philip asked him if he understood what he was reading, he shared how he needed someone to guide him. Then from that passage, Philip was able to announce the good news of Jesus to him. Similarly, the nine chapters in this volume serve as a type of guide for discovering Christ in this largest prophetic book of the Bible. They unlock many confusing passages while also revealing our Savior. Beginning with Isaiah's life-changing vision of God, Stephen Kaung then considers some of the more famous passages about the birth of the Lord Jesus, His life, and His suffering at the cross. We are guided through Scriptures on the future kingdom as well as essential help for our present situation in the church. As the Ethiopian found Christ through Isaiah and "went on his way rejoicing," may we too find Christ our Redeemer in Isaiah and be filled with joy at the discovery.
