Paul sought to show how the gospel message of justification by faith in Christ should humble the contrary Jewish and Gentile Christians of his day. Humbled, both groups were obligated to recognize God’s grace and be united as a single sacrifice unto the Lord (Rom 12:1-2) singing with one voice of praise to God (Rom 15:1-7). Romans 9-11 plays a significant role in the development of Paul’s argument. Paul expounded specific points in Scripture’s storyline to help his audience understand God’s fairness as a judge, and grace toward all in Christ.
(1) In Rom 9:1-18, Paul recalled God’s sovereignty over the lives of Jacob, Esau, and Pharaoh to argue that God was sovereign over the hardening of the Jews in his day. Paul called his audience to consider that the present situation of the early church was in accord with the sovereignty of God—displayed in the miraculous birth of Isaac and the casting out of Ishmael (Rom 9:6-9; Gen 21:12; 18:10, 14), and the announcement that Esau, the older son of Isaac and Rebekah, would serve the younger (Rom 9:10-13; Gen 25:23; Mal 1:2-3). Further, if during the exodus God displayed His sovereignty over Moses and Pharaoh, what human could question God for allowing things to turn out such that the Gentiles were now also revealed to be objects of God’s mercy (Rom 9:19-24; Exod 33:19; 9:16)?
(2) In Rom 9:23-33, Paul fused phrases from Hosea and Isaiah to argue that only by faith could Jews or Gentiles enjoy God’s righteousness. Hosea described God’s redeeming love for Israel. In Rom 9:25-26, Paul took up the prophet’s words in Hos 2:23 and 1:10, placing Gentiles as the referent of the Lord’s mercy. Paul then employed Isa 10:22-23; 28:22; and 1:9 in Rom 9:27-29 as a historical precedent that God would save only a remnant of the descendants of Jacob. Jews stumbled by rejecting Jesus and pursuing righteousness through works of the law. Paul portrayed Jesus as a rock of salvation for all who believed upon Him for righteousness but a stumbling block for those of Israel clinging to the law for righteousness. The Lord told Isaiah to fear Him even though Israel would stumble over their God (Isa 8:14) and trust death rather than the Lord (Isa 28:16). In Rom 9:33, Paul used Isa 8:14 and 28:16 to portray Jesus as the stone God had established as the Savior of His people.
(3) In Rom 10:1-10, Paul combined phrases from Leviticus and Deuteronomy to contrast righteousness that comes through the law and righteousness attained by faith. In Leviticus 18, Moses warned Israel that when they entered the land, they were to avoid both the practices they had witnessed in Egypt and the idolatry of the nations in Canaan. “Keep these statutes and ordinances,” Moses said, “A person will live if he does them” (Lev 18:5). Paul proposed in Rom 7:10 that though Jews thought the law would bring life, it brought death. For those who believe, Paul countered, Christ is the end of the law for righteousness (Rom 10:4). Righteousness by faith does not require someone to rise to heaven (Deut 9:4; 30:12) or go to the depths of the earth (Deut 30:13), Paul wrote in Rom 10:6-7. They only needed to believe in their heart the message of Christ as Lord and confess that message with their mouth (Rom 10:8-10).
(4) In Rom 10:11-21, Paul wove together verses from the prophets to portray both God’s faithfulness toward those who believe and Israel’s hardness in rejecting righteousness by faith. Paul noted in Rom 10:11-16 that though Isaiah and Joel announced the Lord’s faithfulness to His word of deliverance (Isa 28:16; Joel 2:32)—and sent messengers to Israel (Isa 52:7)—Israel failed to believe (Isa 53:1). So pervasive were the prophets’ messages to Israel that Paul likened them to the way that the heavens declare the glory of God (Ps 19:4). Moses predicted that the Lord would use pagan nations to discipline His people for their idolatry (Deut 32:21) and Isaiah prophesied that the Lord would be found by people who were not looking for Him (Isa 65:1). Paul wrote that the Lord had given understanding to the Gentiles, provoking Israel to jealousy as they rejected God’s offer of righteousness by faith (Rom 10:19-20).
(5) In Rom 11:1-10, Paul cited statements from Moses and David to supplement Elijah’s observation that the Lord is able to preserve a remnant in Israel though the nation remains hardened. After Elijah confronted the prophets of Baal on Mount Carmel, he became afraid and ran from King Ahab and Jezebel (1 Kgs 19:1-3). Elijah thought he was all alone but the Lord informed Elijah that He had preserved a remnant of 7,000 who had not worshipped Baal (1 Kgs 19:10, 14, 18). Paul wrote that the Lord had preserved a remnant chosen by grace to believe upon Christ for righteousness (Rom 11:3-6) though the nation wandered in darkness just as Moses (Deut 29:4) and David (Ps 69:22-23) had said (Rom 11:8-10).
(6) In Rom 11:26-27, Paul wrote that the new covenant promises would be realized in the chosen remnant of Israel. Paul warned the Gentiles not to boast over their Jewish neighbors because the Lord had hardened Israel for a time. Isaiah prophesied that the Lord would send a deliverer to turn away godlessness from Israel (Isa 59:20-21), and Isaiah’s prophecy assured Paul that the Lord would one day awaken Israel to forgiveness of sin in Christ—just as Jeremiah prophesied (Jer 31:31-34).
(7) In Rom 11:34-35, Paul joined phrases from Isaiah, Job, and Jeremiah to present God’s wisdom in judgement of Jews and Gentiles. Paul’s frame of mind at the end of Romans 11 shared points of contact with Isaiah in Isa 40:13. The prophet announced that the days of Israel’s punishment were over; God was going to redeem Israel and shepherd His people. In order to underscore the Lord’s ability to redeem Israel, Isaiah described God’s supremacy over creation. Likewise, the Lord showed Job His wisdom by presenting Job with vignettes of how He ruled creation (Job 41:11). Though fools prophesied to Jeremiah and Judah that the Lord would not display His wrath against their sin, Jeremiah understood that the counsel of the Lord would prevail (Jer 23:18). Paul brought the voices of the prophets and Job together to depict God’s wisdom in salvation history. From God, through God, and to God were all things necessary for sinful Jews and Gentiles to receive God’s righteousness.

Romans 12-14
Romans 12 begins a new section of the epistle. Paul began his letter by setting out his apostolic call, personal affections, and desire to preach the gospel in Rome (Rom 1:1-17). After indicting both Jews and Gentiles for their sin (Rom 1:18-3.20), Paul argued that through faith in Christ any sinner can receive right standing before God (Rom 3:21-26). As a result, no Jew or Gentile could boast over his neighbor (Rom 3:27-31). To establish the validity of this proposition, Paul called his readers to consider both Abraham and David—justified by faith and not works of the Mosaic law (Rom 4:1-25). Having set forth and illustrated his proposition, Paul went on to establish two further points. First, Paul encouraged his audience that despite their sinful past and present sufferings, they were secure in Christ by the Holy Spirit (Rom 5:1-8.39). Second, Paul maintained that God is sovereign over Jews and Gentiles coming to believe in Christ (Rom 9:1-11:36).
In Romans 12-14, Paul set out the implications of God’s fairness toward Jews and Gentiles, citing Old Testament passages to illustrate his argument.
(1) In Rom 12:19, Paul combined phrases from Deuteronomy and Proverbs to urge his audience that they should act mercifully toward their enemies. In Deuteronomy 32, Moses indicted Israel for their waywardness. Vengeance belonged to God, Moses said, and He would repay the wrongdoing of His people (Deut 32:35). Since God was faithful to repay Israel by sending them into exile, Paul assured his audience that they could trust God to take care of those who might oppose them. Paul urged the Romans, in accord with Prov 25:21-22, to join with God as He exhibited His wrath against their foes. As the Roman Christians blessed their enemies—giving them food when they were hungry, a drink when they were thirsty—the church would heap burning coals upon the heads of those who opposed Christ and His church (Rom 12:20-21).
(2) In Rom 13:8-9, Paul said that the command for Israel to love their neighbors as themselves summed up all other commandments. In Leviticus 19, Moses set forth various laws for how Israel was to live distinctly as God’s people in Canaan. Israel’s activities and manner of life were to reflect God. Moses said in Lev 19:18, “Do not take revenge or bear a grudge against members of your community but love your neighbor as yourself. I am the LORD.” Following Jesus’ teaching in Matt 19:19, Paul saw Moses’ statement as an umbrella for the Ten Commandments (Exod 20:1-17; Deut 5:6-21). Because love does no wrong to a neighbor, Paul argued, love fulfills the law (Rom 12:10; Matt 5:17-20; John 13:34-35). Paul directed his readers to love one another by putting on the armor of light, avoiding carousing, drunkenness, sexual immorality, promiscuity, quarreling, and jealousy (Rom 13:13). Casting off their old habits, Paul urged the Romans to “put on the Lord Jesus Christ, and make no plans to satisfy the fleshly desires” (Rom 13:14).
(3) In Rom 14:11, Paul cited Isaiah’s prophecy concerning God’s holiness and power to save. In Isaiah 45:14-25, the prophet warned Israel not to trust in the surrounding nations but to know the Lord God alone as their savior. So powerful is God to save, that Isaiah invited the nations to come, bow down, and find refuge in Israel’s God (Isa 45:23). Paul employed Isaiah’s prophecy to accentuate that God is the Judge and Savior of both Jews and Gentiles. According to Paul, Jews who esteemed food laws were weak in faith. Paul was concerned that the Jews’ weakness might incite the Gentiles to look down on their Jewish brothers, causing division in the congregation. Paul thus urged both Jews and Gentiles to avoid arguing about debatable issues like Jewish food laws and holy days (Rom 14:1-6). Since God alone is the Judge of all humanity, concerning these nonessential issues Paul said, “Whoever eats, eats to the Lord, since he gives thanks to God; and whoever does not eat, it is to the Lord that he does not eat, yet he thanks God. For none of us lives to himself, and no one dies to himself. If we live, we live to the Lord; and if we die, we die to the Lord. Therefore, whether we live or die, we belong to the Lord” (Rom 14:6-8). In accord with Isaiah’s presentation of God as Judge, the Jewish and Gentile Christians in Rome were to refrain from judging one another’s cultural preferences (Rom 14:11). “Each of us will give an account of himself to God,” Paul wrote (Rom 14:12).
