How did Christ fulfill the prophecies of Isaiah 49:5-6 that Israel would be gathered to Him, and that He would be a light to the gentiles?

Have these prophecies been completely fulfilled, or only partially fulfilled? 

Isaiah 49:5 - 6

ESV - ⁵ And now the Lord says, he who formed me from the womb to be his servant, to bring Jacob back to him; and that Israel might be gathered to him - for I am honored in the eyes of the Lord, and my God has become my strength - ⁶ He says: "It is too light a thing that you should be my servant to raise up the tribes of Jacob and to bring back the preserved of Israel; I will make you as a light for the nations, that my salvation may reach to the end of the earth.
