The sermon opens in Malachi 3:6-12, the fifth of the prophet's disputations with a spiritually numb, post-exilic Israel, and frames the whole passage around the doctrine of God's covenant faithfulness. A covenant, the sermon explains, is a mutual promise between two parties, sustained only so long as both sides keep their end of it. Israel has repeatedly broken its covenant with the Lord, yet the covenant still stands—not because Israel has been faithful, but because God does not change. "I the Lord do not change; therefore you, O children of Jacob, are not consumed" (Malachi 3:6) is read as the ground of Israel's continued existence: God binds himself irrevocably to his promises even when his people falter, and his call to "return to me and I will return to you" is not a transactional precondition for love but an invitation rooted in mercy already shown. That mercy is traced through the book of Malachi itself—God disciplines Israel with covenant curses rather than destroying them outright, and even sends a prophet to reason with a rebellious people, likened to a husband pursuing an unfaithful wife rather than abandoning her.

Israel's response to God's call, however, is indignant self-justification: "How shall we return?" (v. 7), a question that reveals a people unaware of their own guilt. God answers directly—they have been robbing him, not through secret theft but through forceful withholding, in their tithes and contributions (v. 8). The sermon then traces the history of tithing from its voluntary origins with Abraham and Jacob, through its codification as compulsory law under Moses (Leviticus 27:30), to its function in supporting the landless tribe of Levi and, every third year, the poor and sojourners within Israel's towns (Deuteronomy 14:28-29). Tithes were not merely handed over but celebrated—brought to the temple or local storehouses and consumed in festive meals (Deuteronomy 14:22-23)—so that Israel would "learn to fear the Lord" by tangibly witnessing his provision. The sermon notes that this law was chronically neglected throughout Israel's history, citing Nehemiah's short-lived reforms, and that Malachi is set in the period just before that reform, when withheld tithes brought covenant curses on the land. Remarkably, God then does something he rarely does: he invites his people to test him, promising that obedience in tithing will be met with overflowing blessing, protection from the "devourer," and a land so fruitful that surrounding nations will call Israel blessed (vv. 10-12).

Turning to application, the sermon argues that tithing belongs to Israel's civil law—law given specifically to govern the nation of Israel, tied to its land, its Levitical priesthood, and its temple—and that this civil law, like laws on land boundaries or levirate marriage, expired with the political nation of Israel and has been succeeded by the New Testament church. Because tithes were levied only on agricultural produce and funded institutions (Levites, temple) that no longer exist, a flat 10% requirement is not carried over into the New Covenant. The moral principles behind the law, however, remain binding: God still wants his people to fund kingdom ministry, to care for the poor and needy (a task the sermon notes the church often neglects in practice), to give in proportion to income (1 Corinthians 16:2), to give as a celebration of God's kindness, and above all to give generously and cheerfully rather than under compulsion (2 Corinthians 9:7; 2 Corinthians 8:7). The sermon points to Ananias and Sapphira as proof that the New Covenant removes any fixed quota—their sin was not withholding money but lying about a gift they were never obligated to make—and holds up the widow's two coins and Zacchaeus's fifty-percent restitution as examples of New Covenant giving that exceeds the old tithe precisely because it flows from gratitude rather than law.

The sermon closes by pressing this logic to its full weight: if believers are called to offer their whole selves as a living sacrifice, it is inconsistent to withhold merely a portion of their wallets. Material provision is not abandoned in the New Covenant either—Jesus' teaching to pray for daily bread and to seek first the kingdom (echoed from the Sermon on the Mount) is presented as the continuing, non-extravagant but sufficient promise underneath New Covenant generosity. The concluding appeal reframes the whole sermon's thesis: giving is not a burdensome duty extracted from reluctant hearts but a joyful privilege extended to people who have already received far more from God's love in the gospel than they could ever return.
