This lesson begins by warning against a minimalist view of God that leaves gaps in preaching and teaching—gaps the culture will gladly fill. When the church stops treating God as “Holy, holy, holy,” it drags Him down from the transcendent to the familiar, and a secular mindset takes root. Once truth, beauty, goodness, and justice are defined subjectively rather than by the God who is their source, society enters a race to the bottom that eventually swallows even “conservatism,” because conservatism without Christ is built on expediency, not principle, and therefore preserves nothing. The remedy is to recover the biblical God and, by doing so, recover biblical definitions of justice, goodness, and truth.

Justice is introduced as “receiving what you deserve,” but our culture—and often the church—assumes man is mostly good, which dulls the seriousness of sin and destroys the logic of the gospel. Paul corrects this by placing us under the law as God’s standard: the law stops every mouth, exposes sin, and proves that no human being can be justified by works. Jew and Gentile alike stand condemned, whether with the law or without it. Yet Paul’s “but now” announces hope: the righteousness of God is revealed apart from the law, while the Law and the Prophets still bear witness to it. The Prophets point forward to Christ’s suffering servant, and the sacrificial system prefigures substitution—spotless blood offered for guilt—culminating in the true Lamb of God. Salvation is accessed by faith alone, uniting former enemies into one people brought near by the blood of Christ.

The heart of the mechanics is propitiation: because God is holy, just, omniscient, immutable, and sovereign, He must punish sin—His wrath is real and righteous. But God also provides what His justice requires. In Christ, the sinless One is made sin for us so that we might become the righteousness of God. Like the ram provided in place of Isaac, Christ is the provided substitute; like Isaiah 53, He is crushed as an offering for sin. The lesson closes by preparing to answer objections—especially claims that penal substitution divides the Trinity or that biblical judgments undermine God’s justice—by grounding everything in the holy character of God and the mercy He Himself has ordained.
