We can learn a great deal from the book of Isaiah. While we don’t have a lot of information about his life, his inspired writings and prophecies have been preserved for generations in the Bible. The prophecies of Isaiah point to the end of age when Jesus Christ will return and set up the Kingdom of God. The book is also filled with warnings – warnings of the Day of the Lord and warnings to Israel and Judah which are very relevant to us today. We should take these warnings seriously. If we pay attention to these warnings, we can be assured of the promises of mercy and salvation through Jesus Christ.
