The meaning of the name is "Yahweh is Salvation" and it really seems fitting based on all of the writings in this book. He is commonly called the "Saint Paul of the Old Testament" because of the scope and clarity of the message contained in this book.
The first 39 chapters of this book loosely correspond to the 39 books of the Old Testament in that they condemn sin and warn of judgement. The last 27 chapters loosely correspond to the 27 books of the New Testament in that they give the message of hope and salvation.
"The vision concerning Judah and Jerusalem that Isaiah son of Amoz saw during the reigns of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah." NIV translation
The book opens by telling us about the author and, by listing the kings, it gives us the time in which it happened. It is estimated that the book was written from about 740 to 681 B.C.
"Hear, O heavens! Listen, O earth! For the Lord has spoken: 'I reared children and brought them up, but they have rebelled against me. The ox knows his master, the donkey his owner's manger, but Israel does not know, my people do not understand. Ah, sinful nation, a people loaded with guilt, a brood of evildoers, children given to corruption! They have forsaken the Lord; they have spurned the Holy One of Israel and turned their backs on him.'" NIV translation
Now, the prophet begins to share the very words of God. You can almost feel the sadness in this passage as God laments at how his people have abandoned him. He compares them to various animals who by contrast always know their master and their home. These very words seem as fitting today in our society and even in our "churches" as they were when they were written.
"'Why should you be beaten anymore? Why do you persist in rebellion? Your whole head is injured, your whole heart afflicted. From the sole of your foot to the top of your head there is no soundness- only wounds and welts and open sores, not cleansed or bandaged or soothed with oil.'" NIV translation
Isaiah continues to share the words of God and God asks his people some questions. You can almost feel the compassion as God describes the personal effects of their abandoning Him and asks why they continue in that way. The same compassion should be a part of us as Christians as we see the suffering of those around us.
