Malachi 4

“For behold, the day comes, burning like a furnace, when all the proud and all who work wickedness will be stubble. The day that comes will burn them up,” says the LORD of Armies, “so that it will leave them neither root nor branch.

But to you who fear my name shall the sun of righteousness arise with healing in its wings. You will go out and leap like calves of the stall.

You shall tread down the wicked; for they will be ashes under the soles of your feet in the day that I make,” says the LORD of Armies.

“Remember the law of Moses my servant, which I commanded to him in Horeb for all Israel, even statutes and ordinances.

Behold, I will send you Elijah the prophet before the great and terrible day of the LORD comes.

He will turn the hearts of the fathers to the children and the hearts of the children to their fathers, lest I come and strike the earth with a curse.”

Overview.
This chapter concludes the book of Malachi with a final oracle that contrasts the fate of the wicked and the blessed hope of the righteous, culminating in a promise of restoration and covenant renewal. It looks forward to the coming day of the Lord as both a day of judgment and salvation, while calling God’s people to faithfulness through remembrance of the Mosaic law and anticipation of a prophetic forerunner.

Flow.

The chapter opens with a vivid depiction of the day of the Lord as a purging fire that will utterly consume the proud and wicked, leaving them like ash (v. 1).
In contrast, those who fear God’s name receive the promise of deliverance and joy, symbolized by the rising of the “sun of righteousness” bringing healing and renewal (v. 2).
The redeemed are pictured as victorious over the judged wicked, whom they will trample as ashes underfoot, emphasizing the completeness of divine justice (v. 3).
The exhortation to remember the law of Moses is followed by a promise of Elijah’s coming to restore right relationship within families and the covenant community before the final day (vv. 4–6).

Connections.
Following chapter 3, which describes the coming messenger and the refining judgment of the Lord as well as the call to faithful stewardship and covenant loyalty, chapter 4 intensifies the eschatological vision and closes the prophetic canon. It reaffirms the necessity of repentance and readiness for the day of the Lord, themes that have been woven throughout Malachi’s oracles. The reference to Elijah directly picks up the earlier mention of the messenger preparing the way (), now identifying him as Elijah, and thus links the present call to faithfulness with the future divine intervention. This closure of the final prophetic book points forward to the arrival of John the Baptist and the ministry of Jesus, which the New Testament explicitly connects to these promises (e.g., , ), setting the stage for the gospel proclamation.

What it teaches.
The chapter affirms the final judgment and resurrection hope central to biblical eschatology, where God will fully vindicate the righteous and destroy the unrepentant (WCF 3.3, 33.2). The “sun of righteousness” signifies the messianic age, in which divine salvation brings healing and joy, fulfilled in Christ’s first coming and consummated at His return (HC LD 19). The command to remember the law () underscores continuity with God’s covenant revelation, while the promise of Elijah points to a divinely sent forerunner who prepares the people for the Lord’s appearance (Canons of Dort, First Head, Art. 7). The restoration of hearts between generations reflects the renewal of covenant loyalty and familial faithfulness, which the Spirit works as a sign of readiness for the Lord’s day.
