Covenant mercy, forgiveness of sins, and preparation of God’s people converge with prophetic new-covenant restoration themes that Luke-Acts will develop further.

Matthew's 'for the remission of sins' and covenant setting strongly belong to Jeremiah's promised covenant-renewal world, where God forgives iniquity and remembers sin no more, though Matthew does not quote Jeremiah here.

Jeremiah’s new-covenant promise that God’s people will know him without dependence on an external mediator provides a canonical trajectory for 1 John’s assurance that the anointing teaches believers as they abide in the received truth.

Hebrews quotes Jeremiah’s new-covenant promise at length and makes it central to the book’s covenant argument. Jeremiah 31:31–34 supplies the promise of an inwardly written law, renewed covenant relationship, knowledge of the LORD, and decisive forgiveness; Hebrews 8:8–12 directly reproduces that oracle and applies it within Christ’s covenant ministry.

Nehemiah’s community makes a sincere written covenant, but the book soon records renewed failure; Jeremiah promises a new covenant in which God’s law is written on the heart and sins are forgiven. The contrast creates a strong problem-to-solution trajectory from external recommitment toward inward covenant renewal.

Ezra’s difficult ending proves that geographic return, rebuilt temple, priesthood, and Torah instruction do not by themselves solve covenant unfaithfulness. Jeremiah’s new-covenant promise reaches deeper, speaking of God’s law written on the heart and sins forgiven. The relationship explains why Ezra’s restoration can be real yet still leave the canonical story unfinished.

Jesus explicitly names the new covenant in his blood.

Paul preserves Jesus’ words over the cup: “This cup is the new testament in my blood,” explicitly identifying the Jeremiah 31 new-covenant hope with Christ’s death.

Paul calls himself and his coworkers “ministers of the new testament,” then contrasts letter and Spirit, developing Jeremiah’s promised new-covenant transformation in apostolic ministry.

Jeremiah’s promise of covenant instruction written inwardly helps explain Paul’s living-letter language.
