Isaiah 51:4
1 “Listen to me, you who pursue godliness, who seek the Lord. Look at the rock from which you were chiseled, at the quarry from which you were dug. 2 Look at Abraham, your father, and Sarah, who gave you birth. When I summoned him, he was a lone individual, but I blessed him and gave him numerous descendants. 3 Certainly the Lord will console Zion; he will console all her ruins. He will make her wilderness like Eden, her arid rift valley like the garden of the Lord. Happiness and joy will be restored to her, thanksgiving and the sound of music. 4 Pay attention to me, my people. Listen to me, my people! For I will issue a decree, I will make my justice a light to the nations. 5 I am ready to vindicate, I am ready to deliver, I will establish justice among the nations. The coastlands wait patiently for me; they wait in anticipation for the revelation of my power.
Romans 1:16
13 I do not want you to be unaware, brothers and sisters, that I often intended to come to you (and was prevented until now), so that I may have some fruit even among you, just as I already have among the rest of the Gentiles. 14 I am a debtor both to the Greeks and to the barbarians, both to the wise and to the foolish. 15 Thus I am eager also to preach the gospel to you who are in Rome. 16 For I am not ashamed of the gospel, for it is God’s power for salvation to everyone who believes, to the Jew first and also to the Greek. 17 For the righteousness of God is revealed in the gospel from faith to faith, just as it is written, “The righteous by faith will live.”
Notes and References
"... The hope of the psalmist is that God's eschatological vindication of Israel will serve as a demonstration to the whole world of the power and faithfulness of Israel's God, a demonstration that will bring even Gentiles to acknowledge him. Paul shares the psalmist's eschatological vision; that is why he insists in Rom. 1:16 that the gospel is a word of salvation to the Jew first and then subsequently also to the Greek, although, as we shall see, he has subjected this scenario to certain dialectical revisions. Similarly, the promise of a future universal manifestation of God's salvation and rig~teousness sounds throughout the latter chapters of the prophetic book of Isaiah ..."
