Truth of Gods Faithfulness is seen in the fact that he has sent his Son, Yeshua Ha Massiach; Jesus Christ to die for our sins. In Isaiah we find in this episode of that truth. The very works, or wonderful things that have been done, can be seen from the heavens he created to the earth, and all things therein. We can behold how he dealt with Israel. Even in His Judgment, there is mercy; until the final great day when all souls will appear before him. We follow Isaiah's prophecy and end up in the most glorious of places for any believer to be. It exudes hope and see's the hand of God at Work.
