He says, “You will do more than restore the people of Israel to Me. I will make you a light to the Gentiles, and you will bring My salvation to the ends of the earth.” Isaiah 49:6
The second servant song is Isaiah 49:1-13 describing the role the Messiah will have. From conception, He was set apart to bring salvation to humanity. It would at times seem like His work would be useless because so many would reject Him. Yet, He would not give up on us. His purpose was to bring light and salvation to all people. He will release those in darkness and ignorance.
And He said, “Yes, it was written long ago that the Messiah would suffer and die and rise from the dead on the third day. It was also written that this message would be proclaimed in the authority of His name to all the nations, beginning in Jerusalem: ‘There is forgiveness of sins for all who repent.’ Luke 24:46-47
