from the new testament

• In this lengthy letter, Paul explains the gospel from start to finish. His reason appears to be two-fold. First, the Jewish and Gentile believers were having disagreements (Romans 14:1–4) that centered on the law’s role in salvation and on the benefits for Jews of having the law (Romans 2:17–29; 3:1–8). Secondly, Paul, as a missionary, hoped to travel to Spain and, since he’d never met the Roman believers before (Romans 1:8–13), was introducing himself and seeking support on his way there (Romans 15:23–24, 28–29).
• The letter opens with Paul’s thesis statement: “For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith for faith, as it is written, ‘The righteous shall live by faith’” (Romans 1:16–17). The majority of the rest of the letter details why the gospel is the same universally, God’s righteousness revealed in Jesus, and how one is justified through faith.
• Paul started by explaining that everyone was sinful. He began with a statement addressed directly to Gentiles in Romans 1:18–32. He said that “they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened” (Romans 1:21).
• Then Paul turned to the Jews (Romans 2), who thought they were righteous because they had the law. However, he argued, “it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified” (Romans 2:13). He noted the general Jewish system of self-righteous hypocrisy, saying, “While you preach against stealing, do you steal? You who say that one must not commit adultery, do you commit adultery? You who abhor idols, do you rob temples? You who boast in the law dishonor God by breaking the law. For, as it is written, “The name of God is blasphemed among the Gentiles because of you” (Romans 2:21–24).
• Paul was not saying that Jews were particularly sinful, but was deflating their pride that they were righteous because they were given the law. He said: “What then? Are we Jews any better off? No, not at all. For we have already charged that all, both Jews and Greeks, are under sin” (Romans 3:9). To prove his point, Paul quoted from multiple Old Testament passages that teach that “None is righteous, no, not one” (Romans 3:10), “no one understands; no one seeks for God.” (Romans 3:11), and “no one does good, not even one” (v 12). Rather than saving, “by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin” (Romans 3:20).
• Because “all have sinned and fall short of the glory of God” (Romans 3:23), how can anyone be saved? Because “now the righteousness of God has been manifested apart from the law” (Romans 3:21). God’s righteousness was manifested in Jesus “whom God put forward as a propitiation by his blood, to be received by faith” (Romans 3:25). Being a propitiation means that Jesus died a sacrificial death for sinful men and women. That death was “to show [God’s] righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus” (Romans 3:26). Therefore, because it is Jesus’ righteousness which saves, there is no boasting (Romans 3:27a), it isn’t based on the Law (Romans 3:27b–28), and is available to both Jews and Gentiles (Romans 3:29).
• Having established that Jesus is God’s righteousness outside the Law, Paul explained that justification, being declared legally righteous by God on the basis of Jesus’ righteousness, was received through faith. Just like “Abraham believed God, and it was counted to him as righteousness” (Romans 4:3), so also “the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness” (v 5).
• Being justified means “we have peace with God through our Lord Jesus Christ” (Romans 5:1) and thus through Him “shall we be saved by him from the wrath of God” (Romans 5:9).
• Paul then addresses the question of how one man’s death can save many people. He did this by contrasting Adam and Jesus (Romans 5:12–21). He said that “just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned … one act of righteousness leads to justification and life for all men” (Romans 5:12, 18). Therefore, “if many died through one man’s trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many” (Romans 5:15). Paul was using the concept of representation, sometimes known as Federal Headship, in which Adam was the head of humanity, and thus his sin brought death to all of humanity, whereas Jesus is the head of all who believe in Him, bringing life to those in Him.
• In chapters 6–7, Paul then explains that the implication of the Gospel is that we are not to sin. “How can we who died to sin still live in it?” (Romans 6:2). Therefore, “Let not sin therefore reign in your mortal body, to make you obey its passions” (Romans 6:12). However, though we have been freed from sin (Romans 6:15–23), we are not perfectly holy, being at war with or remaining sinful flesh (Romans 7:21–23). This is why Paul could cry, “I do not understand my own actions. For I do not do what I want, but I do the very thing I hate” (Romans 7:15) and “Wretched man that I am! Who will deliver me from this body of death?” (Romans 7:24).
• Chapter 8 concludes Paul’s discussion on justification as he reminds himself that, despite his struggles with sin, “There is therefore now no condemnation for those who are in Christ Jesus. 2 For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death” (Romans 8:1–2). That confidence comes from knowing that believers have been adopted as God’s children (Romans 8:12–16) and means that there is a future glory when all suffering will be gone and believers will be revealed as such (Romans 8:18–21). In the meantime, “If God is for us, who can be against us?” (Romans 8:31). If God gave His Son to die, He will surely keep His people (Romans 8:32). This means that there is no one, nor thing, that can separate us from the love of Christ (Romans 8:35–39).
• In Chapters 9–11, Paul then addresses the question of what the Gospel means for Israel. God’s promises were to them (Romans 9:4–5). However, “it is not as though the word of God has failed” (Romans 9:6a). This is because “not all who are descended from Israel belong to Israel” (Romans 9:6b). Paul explained that the promises of salvation to Israel were extended to those who, like Abraham, believed God (Romans 9:7–8). He showed that God’s promises came to the Gentiles because of Israel “did not pursue [righteousness] by faith, but as if it were based on works” (Romans 9:32). However, the mystery in this is that God planned Israel to stumble so that Gentiles would be saved and make Israel jealous (Romans 11:11) which will one day lead to all of Israel being saved (Romans 11:25–26).
• Turning back to the Gospel, Paul then gives several implications of those who have been justified by faith (Romans 12–14). They are “not [to] be conformed to this world, but [to] be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect” (Romans 12:2). They are to serve one another with their gifts (Romans 12:3–8) and to “Let love be genuine. Abhor what is evil; hold fast to what is good” (Romans 12:9). They are to leave their enemies to God’s judgment, showing them love instead of hate (Romans 12:14–21) and to submit to the government because its authority came from God (Romans 13:1–7). In summary, “Love does no wrong to a neighbor; therefore love is the fulfilling of the law” (Romans 13:10).
• In addition to general love, they were to particularly love the brethren. Rather than quarreling over matters of Christian liberty, such as what one could or could not eat, they were to defer to each other (Romans 14). In this way, love is shown by being willing to give up on one’s liberty to keep another believer from stumbling (Romans 14:13, 21). The example of this is Christ: “For Christ did not please himself, but as it is written, ‘The reproaches of those who reproached you fell on me’” (Romans 15:3).
• Paul summarizes his letter, reminding them that the Gospel is for both Jews and Greeks (Romans 15:8–13) and explaining that Jesus sent him specifically to minister to the Gentiles (Romans 15:14–21). Thus, though hindered until now, he desired to go to Spain and stop in Rome along the way (Romans 15:22–29). Paul then asked for their prayers (Romans 15:30–33).
• Paul ends by sending his greetings to a few individuals (Romans 16:1–16), offers one more warning against divisions (Romans 16:17–19), relays other greetings (Romans 16:21–23), and ends with a doxology, praising God: “to the only wise God be glory forevermore through Jesus Christ” (Romans 16:27).

implications for today

One of the greatest temptations in the Christian life is to think the gospel is only for the moment we were saved. The book of Romans reminds us that the gospel is not just the starting point of our faith—it is the power that sustains and transforms our entire lives (Romans 1:16–17). We don't earn God's love by performing better, serving more, or cleaning ourselves up. We stand before Him because of Christ's righteousness, not our own (Romans 3:21–26; 5:1). That frees us from both pride when we're doing well and despair when we fail.

At the same time, Romans makes it clear that God's grace is never an excuse for complacency. The same grace that justifies us also changes us (Romans 6:1–14). Every day is an opportunity to reject sin, renew our mind with God's truth, and intentionally offer our lives to Him as a living sacrifice (Romans 12:1–2).

Romans also challenges us to look beyond ourselves. The gospel should shape the way we treat others—with genuine love, humility, forgiveness, patience, and a willingness to put their spiritual good ahead of our own personal preferences (Romans 12:9–21; 14:13–19). Whether we're at home, at work, in church, or online, every interaction is an opportunity to display the transforming power of the gospel.

Finally, when life is difficult or your faith feels weak, Romans calls us to rest in God's unshakable promises. There will be suffering, ongoing battles with sin, and seasons of uncertainty, but believers have the assurance that none of those can separate us from the love of God in Christ Jesus (Romans 8:18–39). Our confidence isn't found in our ability to hold onto God; it's found in His faithfulness to hold us. With that assurance we can have the courage to live boldly for His glory each day.
