Romans 9–11 represents one of the most theologically dense and emotionally charged sections of Paul's writing. After the soaring triumph of Romans 8 — where nothing can separate us from the love of God — Paul turns immediately to a question that is breaking his heart: if God's promises are so certain, why have most of the Jewish people rejected Jesus? Has God's word failed? Paul's three-chapter answer explores God's sovereign choice, human responsibility, the mystery of hardening, the inclusion of the Gentiles, and ultimately the breathtaking scope of God's mercy toward all. And at the center of it all is a verse — Romans 10:13 — that, when traced to its fulfillment in Acts 2:38, reveals the name by which all humanity must be saved.
"That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation."
"For 'whoever calls on the name of the LORD shall be saved.'"
"And so all Israel will be saved, as it is written: 'The Deliverer will come out of Zion, and He will turn away ungodliness from Jacob.'"
Paul opens Romans 9 with one of the most extraordinary personal statements in his letters: "I tell the truth in Christ, I am not lying, my conscience also bearing me witness in the Holy Spirit, that I have great sorrow and continual grief in my heart. For I could wish that I myself were accursed from Christ for my brethren, my countrymen according to the flesh" (vv.1–3). This is not rhetorical hyperbole — this is the genuine anguish of a man who understands what is at stake for his people and who loves them with a love that mirrors the love of God. He enumerates the great privileges of Israel: the adoption, the glory, the covenants, the law, the service of God, the promises, the patriarchs — and, greatest of all, from Israel came "Christ came, who is over all, the eternally blessed God" (v.5). The Messiah was Jewish. The promises were given to Israel. And yet most of Israel has rejected Him.
Paul addresses the theological crisis head-on: "But it is not that the word of God has taken no effect" (v.6). Just because ethnic Israel has largely rejected Jesus does not mean God's promises have failed — because "they are not all Israel who are of Israel." Not everyone born into the physical lineage of Abraham is counted as a spiritual heir of the covenant promises. God has always operated by a principle of election — sovereign, purposeful choice that predates human merit or effort. He chose Isaac over Ishmael before either was born. He chose Jacob over Esau before either had done anything good or evil — "that the purpose of God according to election might stand, not of works but of Him who calls" (v.11).
Paul defends God's sovereign right to make these choices against the charge of unrighteousness. The potter has authority over the clay. God said to Moses: "I will have mercy on whomever I will have mercy, and I will have compassion on whomever I will have compassion" (v.15, quoting Exodus 33:19). This is not arbitrariness or cruelty — it is the prerogative of a sovereign God whose ways are higher than human ways and whose understanding is beyond our comprehension. The chapter closes with the remarkable reversal that Gentiles who did not pursue righteousness have attained it through faith, while Israel, pursuing righteousness through the law, has not attained it — because they sought it by works rather than by faith (vv.30–31).
Paul's heart for Israel's salvation is palpable: "Brethren, my heart's desire and prayer to God for Israel is that they may be saved" (10:1). He acknowledges their zeal for God, but it is "not according to knowledge" (v.2). They have not understood that Christ is "the end of the law for righteousness to everyone who believes" (v.4). They have been trying to establish their own righteousness through law-keeping while the righteousness of God stands available through faith in Jesus Christ.
Paul then quotes from Deuteronomy 30 to show that the word of faith is not far away, hidden in heaven or across the sea. It is near — "in your mouth and in your heart" (v.8). This leads to the famous confession of Romans 10:9–10: "That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved." This verse has been widely used to support a "sinner's prayer" model of salvation, but it must be read in its full context. "Confession" in the New Testament is not a private, silent prayer — it is a public declaration. The mouth that confesses the Lord Jesus is the same mouth that speaks the name of Jesus in obedient baptism. Belief and confession are the internal and external dimensions of the same saving response.
The chapter builds to its great climax: "For 'whoever calls on the name of the LORD shall be saved'" (v.13, quoting Joel 2:32). This verse raises the defining question: WHICH name? What is the LORD's name? And what does "calling on it" look like in practice? Paul quotes the promise but does not specify the name here. For that answer, we must follow the quotation to its fulfillment. Peter preaches from the same Joel 2:32 passage in Acts 2:21 — and the crowd immediately asks, "What shall we do?" (Acts 2:37). Peter's response in Acts 2:38 tells them exactly how to call on that name: "Repent, and let every one of you be baptized in the name of JESUS CHRIST for the remission of sins; and you shall receive the gift of the Holy Spirit." The name of the LORD in Romans 10:13 is the name Peter commanded them to be baptized in: JESUS.
"I say then, has God cast away His people? Certainly not!" (11:1). Paul is emphatic. The seeming rejection of Israel by God is not total and it is not final. As evidence, Paul points to himself: he is an Israelite, from the tribe of Benjamin, and he has received the gospel. And beyond himself, there is a remnant — a portion of Israel chosen by grace (not by works or merit) who have believed. Just as in the days of Elijah, when God told the prophet who felt completely alone that He had reserved seven thousand who had not bowed the knee to Baal, so now there is a remnant of Israel who have embraced Jesus as the Messiah.
The majority of Israel has experienced a "hardening in part" (v.25) — a judicial blinding that has come as the consequence of their rejection. Paul uses the image of an olive tree to explain the relationship between Israel and the Gentiles. Israel is the cultivated olive tree — the tree with deep roots going back to Abraham. The natural branches (unbelieving Israel) have been broken off because of unbelief. The Gentiles are wild olive branches that have been grafted in, contrary to nature, because of faith. They now share in the nourishment of the root — the covenant promises and the life of God.
But Paul issues a firm warning to Gentile believers against arrogance: "Do not be haughty, but fear. For if God did not spare the natural branches, He may not spare you either" (vv.20–21). The same principle applies to all: you stand by faith. Pride about being "grafted in" while Israel was "broken off" is spiritually dangerous and theologically ignorant. The Gentile believers did not earn their position — they received it by God's grace through faith. And if unbelieving Israel returns to faith, God is perfectly able to graft them back in: "for God is able to graft them in again" (v.23).
"For I do not desire, brethren, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that blindness in part has happened to Israel until the fullness of the Gentiles has come in" (v.25). Paul calls this a "mystery" — not something unknowable, but something previously hidden that has now been revealed. Israel's partial hardening is not permanent. It has a purpose and a timeline. It continues "until the fullness of the Gentiles has come in" — until God's harvest from all nations is complete.
Then comes the breathtaking promise: "And so all Israel will be saved, as it is written: 'The Deliverer will come out of Zion, and He will turn away ungodliness from Jacob; for this is My covenant with them, when I take away their sins'" (vv.26–27). The scope of this promise and its timing in the plan of God have been debated extensively. But the core declaration is unmistakable: God is not finished with Israel. His covenant faithfulness extends to the Jewish people. The Deliverer — Jesus the Messiah — will come out of Zion and accomplish a work of salvation for Israel.
Paul grounds this in the unchanging character of God: "For the gifts and the calling of God are irrevocable" (v.29). God does not take back what He has given and He does not cancel what He has called. His purposes will stand. Israel's rejection of Jesus has become the occasion for the gospel to go to the Gentiles, and the Gentiles' reception of the gospel will become the occasion for Israel's salvation — a cycle of mercy that has God's fingerprints all over it. The section closes with one of the most magnificent doxologies in all of literature: "Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out! For who has known the mind of the LORD? Or who has become His counselor? Or who has first given to Him and it shall be repaid to him? For of Him and through Him and to Him are all things, to whom be glory forever. Amen." (vv.33–36).
Romans 10:13 — "whoever calls on the name of the LORD shall be saved" — is one of the most pivotal verses in Scripture for Apostolic soteriology, and it is frequently misapplied. Many use this verse to teach that salvation comes through a private "sinner's prayer" addressed to an unnamed Lord. But the text and its context demand far more. Paul quotes Joel 2:32, which is the same passage Peter cites at the beginning of his Pentecost sermon in Acts 2:21. Peter builds toward the same conclusion Paul does: all who call on the name of the Lord shall be saved. But when his audience responds with the urgent question, "What shall we do?" (Acts 2:37), Peter does not tell them to bow their heads and repeat a prayer. He tells them exactly how to call on that name: "Repent, and let every one of you be baptized in the name of JESUS CHRIST for the remission of sins; and you shall receive the gift of the Holy Spirit" (Acts 2:38). Paul's own experience confirms this. Ananias said to him: "Arise and be baptized, and wash away your sins, calling on the name of the Lord" (Acts 22:16). For Paul himself, "calling on the name" WAS water baptism in the name of Jesus Christ. The name of the LORD in Romans 10:13 is JESUS — and calling on that name, according to the apostolic pattern, means being baptized in that name, just as Peter commanded and Paul himself obeyed.
