Indeed He says, ‘It is too small a thing that You should be My Servant To raise up the tribes of Jacob, And to restore the preserved ones of Israel; I will also give You as a light to the Gentiles, That You should be My salvation to the ends of the earth.’ ”
Isaiah 49:6 NKJV
I believe this verse is twofold. First, because of the capitalization, it speaks of the role of the Messiah. Messiah will be the Servant of God the Father. He was to teach, raise up Israel in the way they should go. Messiah was there to restore those God had preserved. We know that the Messiah did reach out to the Gentiles to become part of the family of God.
I believe that this was also the role Israel were supposed to fill, including reaching out to the Gentiles. In Leviticus, there is outlined a way for Gentiles to join the family of God, the Jews.
If you are part of the family of God, are you fulfilling these things? Are you a servant of God? Are you teaching those around you the way they should be/ go? Are you one who restores those who have been beaten down? Are you reaching out to the unsaved?
