Light of the nations - Isaiah 49

Isaiah 49:3 He said to me, "You are my Servant, Israel, In whom I will show My glory." 6"... I will also make you a light of the nations so that My salvation may reach to the end of the earth."

V7 mentioned that Jacob as the "despised one, the one abhorred by the nations". Not only does God have the power to redeem(chapter44, psalm 130), He also makes him successful(chapter 48), and further more, He will make him a light of the nations, in whom He will show His glory. Isn't that awesome!
This is such a love letter of God to His chosen people, His prodigal son. He'd do anything for a sinner to return. We should never neglect God's love and His heart for His lost ones.
