The sermon opens Paul's letter to the Romans by unpacking three key words in Romans 1:14–17: righteousness, faith, and gospel, and shows how the gospel binds the first two together as God's plan to save sinners. The preacher first explains righteousness as "the quality of being right," parallel to how goodness is the quality of being good. Unlike a factual claim (it is now daytime in Melbourne), moral rightness is contested, yet Scripture consistently uses the term to describe God getting the moral facts right. God is righteous, the sermon argues, for three reasons: he is Creator and so defines all things; he is the all-powerful final Judge whom no one can overturn or defeat; and, most importantly, he is simply good — in God, moral authority and moral goodness are perfectly one, so that he is not merely right because he is strong, but strong and right because he is good.

The sermon then wrestles with the strange phrase in verse 17, that God's righteousness "is revealed from faith for faith." To reveal means to make something small and hidden clearly visible, as a microscope reveals unseen life in a drop of water. Faith means to believe or trust. The repetition "from faith for faith" is read as a poetic emphasis: God's rightness is shown by faith and only faith — and strikingly, not God's own faith, since God has perfect knowledge and needs none, but the faith of sinful human beings. This seems backwards: surely God's rightness would be shown by rewarding the good and punishing the wicked, not by human belief. Paul resolves the puzzle by quoting Habakkuk 2:4, "the righteous shall live by faith," and the sermon retells Habakkuk's context: the prophet complained that God's righteousness seemed absent because evil persisted in Israel, and God's answer was even more troubling — he would use the more wicked nation of Babylon to judge Israel. Yet God promised Habakkuk that he remains faithful: he would judge Babylon in turn, and he would not abandon his promise to eventually wash Israel clean. Habakkuk's right response was not to demand vindication now but to trust God's unfolding plan — hence, "the righteous shall live by faith."

The sermon presses Paul's deeper reading of that verse: it is not simply that righteous people live characterized by faith, but that faith is the very means by which they are able to live at all before God, because even those called righteous still need the cleansing God promised. No one — not Babylon, not Israel, not even Habakkuk — can pass God's test of righteousness on their own merit; all have sinned, and so all must rely on faith in God's rescuing plan. Crucially, the sermon insists this is not faith as a meritorious act that earns salvation — as though God rewards the sheer effort of believing — but faith as the instrument that receives a salvation accomplished entirely by another. That plan, revealed partially to Habakkuk, is fully unveiled in the gospel: the "good news," from the Greek euangelion, that God sent his only Son, Jesus Christ, because no one could be righteous by their own works. Jesus alone lived righteously and died a righteous death, yet did not die alone — he died in union with all who trust in him, so that when he died, their debt of judgment was paid with him. Standing before the gates of heaven, the believer's answer to "why should you enter?" is not personal goodness but the blood of Christ shed for them.

The sermon then distinguishes "righteous" and "justified" as the same Greek root: becoming righteous by faith is not itself the content of the gospel but describes how the gospel is applied — faith is not what saves, but the sign that Christ's finished salvation has been given to someone. This resolves the apparent tension in Habakkuk's verse: if the righteous live by their own moral perfection, they need no one else's help, but if they live by faith, that implies their own works are insufficient. The tension dissolves once we see that Christ has already fulfilled God's righteousness on the believer's behalf, so that righteousness is found not in oneself but in Christ and credited to the believer. The sermon then turns briefly to Paul's own testimony: called to preach to the nations, he calls himself the "chief of sinners," a former persecutor of the church shown astonishing mercy, and his gospel proclamation flows both from divine obligation and from grateful love. He declares he is "not ashamed of the gospel" precisely because it looked shameful and weak to both Jews (a crucified, defeated Messiah) and Greeks (too simple a message for sophisticated philosophy), yet it alone holds the power to save. The sermon closes by noting that Paul spends the following chapters not proclaiming more good news but describing humanity's sin, because the bad news of universal guilt is what makes the good news of Christ necessary and precious, and calls the church to receive that hard truth so as to treasure Christ all the more.
