The wrath of God against unrighteousness

Paul is not ashamed of the gospel because it is God’s power to save everyone who believes. He then shows why that gospel is so necessary: God’s wrath is already being revealed against people who suppress the truth about him, exchange his glory for idols, and are judicially handed over to deeper moral corruption.

In verses 16-17, Paul states the controlling theme of this section of Romans. The gospel is not merely information about salvation. It is God’s effective power to save those who believe. This saving power is for all without distinction, though it comes “to the Jew first and also to the Greek,” preserving the historical order of God’s saving plan. In the gospel, “the righteousness of God” is revealed. That includes both God’s own righteous character and his righteous saving way of setting matters right for sinners who believe. This righteousness is received by faith from beginning to end, just as Scripture says: “The righteous by faith will live.”

Verse 18 explains why the gospel is so urgently needed. Just as God’s righteousness is revealed in the gospel, God’s wrath is also revealed from heaven against all ungodliness and unrighteousness. This wrath is not only future. In this passage, Paul shows that it is already being revealed in history through God’s judicial act of giving people over to the sins they have chosen. God’s wrath is not a burst of temper. It is his settled, holy judgment against evil.

Paul says people suppress the truth by their unrighteousness. The problem is not that they have no knowledge of God at all. God has made enough known about himself through creation that they are without excuse. Since the creation of the world, his invisible attributes, especially his eternal power and divine nature, have been clearly perceived through what he has made. Creation does not provide the saving knowledge given in the gospel, but it does provide real knowledge that makes people accountable to God.

At the root, human rebellion is not simply intellectual confusion. It is moral and spiritual refusal. Although people knew God in this limited but real sense, they did not glorify him as God or give him thanks. That failure in worship led to failure in thinking. Their reasoning became empty, and their hearts were darkened. Claiming to be wise, they became fools. Instead of honoring the immortal God, they exchanged his glory for images resembling mortal people and animals. This is the great reversal: the Creator is traded for created things.

That exchange shapes the rest of the paragraph. In verse 24, because they exchanged God’s glory for idols, God gave them over in the desires of their hearts to impurity, so that their bodies were dishonored among themselves. In verse 25, Paul restates the point: they exchanged the truth of God for the lie and worshiped and served the creation rather than the Creator. Even here, Paul pauses to affirm that the Creator is blessed forever. Human rebellion does not diminish God’s worthiness to be praised.

In verses 26-27, Paul describes the second judicial handing over. Because of this idolatrous exchange, God gave them over to dishonorable passions. Women exchanged natural sexual relations for unnatural ones, and men likewise abandoned natural relations with women and were inflamed in their desires for one another. Men committed shameless acts with men and received in themselves the due penalty for their error. In this context, Paul presents these acts as part of the wider pattern of exchanged realities and the distortion of the created order. These verses should not be detached from the larger argument about revelation, idolatry, and judgment. At the same time, Paul’s moral judgment here is clear and must not be softened.

In verse 28, Paul gives the third statement that “God gave them over.” Since they did not think it worthwhile to acknowledge God, God gave them over to a depraved mind. There is a fitting correspondence here: they rejected God in their thinking, and God gave them over to corrupted thinking. The result is a life marked by things that ought not to be done.

The list in verses 29-31 shows that Paul is not focusing on one sin alone. Human rebellion spreads everywhere: wickedness, greed, malice, envy, murder, strife, deceit, hostility, gossip, slander, hatred of God, arrogance, boastfulness, inventing evil, disobedience to parents, lack of sense, covenant-breaking, heartlessness, and ruthlessness. The corruption reaches worship, the mind, speech, relationships, family life, and society as a whole.

Verse 32 brings the indictment to its fullest point. People know God’s righteous decree that those who practice such things deserve death, yet they not only do them but also approve of others who practice them. This shows how deep the corruption runs. Sin is not only committed; it is celebrated. Moral judgment itself has become twisted.

This whole paragraph must be read within Paul’s larger argument. Romans 1:18-32 is not his final word about one group of especially sinful people. In the next chapter, he turns to the self-righteous person who judges others and shows that such a person is also without excuse. Paul’s purpose is to prove that all stand under sin and therefore all need the gospel.

So the flow of the passage is clear. The gospel reveals God’s righteousness and saves all who believe. The world reveals God’s wrath against truth-suppressing sin. Humanity has knowingly refused to honor God, exchanged him for idols, and been handed over to increasing disorder in desire, conduct, and judgment. That is why the gospel is necessary, and why Paul is not ashamed of it.
