The Jewish sacrifices, to which God asserts: “My favour is not with you, saith the Lord of hosts, and the offering out of your hands is displeasing to Me,” have ceased—a fact they cannot ignore. Why then do they await another Messiah when the prophecies they read are already fulfilled through Christ? The prophet further asserts in God’s name: “My covenant with him was a covenant of life and peace; I gave it to him for fear, and he feared Me and revered My name. The law of truth was in his mouth, and unrighteousness was not found on his tongue; in peace and truth he walked with Me, and turned many away from sin. For the mouth of the priest shall keep knowledge, and the law shall be sought out of his mouth, because he is the messenger of the Lord of hosts” (Malachi 2:5-7). It should not astonish us that Jesus Christ is referred to as an angel of God Almighty. As He came to humanity in the form of a servant, He serves, while also being a messenger for the good news He proclaimed. The Greek terms indicate that gospel translates as good news and angel as messenger. The prophet also speaks of Him: “Behold, I send my angel, and he shall prepare the way before me; suddenly the Lord whom ye seek, and the angel of the covenant whom ye desire, shall come to His temple: behold, He cometh, saith the Lord of hosts. And who shall endure the day of His coming, and who shall stand when He appears?” (Malachi 3:1-2). Here, the prophet anticipates both the first and second coming of Christ—the first indicated by “He shall come suddenly to His temple,” referring to His body, regarding which Christ stated in the Gospel, “Destroy this temple, and I will raise it up in three days” (John 2:19); the second when He declared, “Behold, He is coming, saith the Lord of hosts. And who shall endure the day of His coming?” This illustrates that the Jews, as found in their scriptures, seek and desire Christ, yet many, blinded by their own righteousness, fail to recognize that He whom they seek has already come.
The covenant referred to by the prophet signifies the New Covenant, which offers eternal promises, contrasting with the Old Covenant, which was based on temporal promises. Many, having invested their hopes in these latter promises and serving the true God with expectations of temporal rewards, become troubled when they observe the wicked enjoying those same rewards. To differentiate between the eternal glory of the New Covenant, bestowed solely upon the virtuous, and the temporary prosperity of the Old, often granted to the wicked, the prophet states: “Your words are bold before Me, saith the Lord. You will say, ‘What do we speak against You?’ You say, ‘The service of God is vain, and what good is it that we have kept His decrees and walked in sorrowful garments before the face of the Lord of hosts? Now we count the haughty happy: those who do iniquity are better off; although they tempt God, they remain unscathed.’ But those who fear God say to one another, ‘The Lord hears this, and before His face is written a book of remembrance for those who fear the Lord and honour His name’” (Malachi 3:13-16). This book symbolizes the New Covenant. The further revelation states: “And they shall be Mine, saith the Lord of hosts, My property in that day which I will make; I will have mercy on them, as a man has mercy on his son who serves him. Then you will again distinguish between the righteous and the wicked, between those who serve God and those who do not. For behold, the day will come that burns like a furnace; all the arrogant and wicked will be stubble, and that coming day will set them ablaze, saith the Lord of hosts, leaving them neither root nor branch. But for you who revere My name, the Sun of righteousness shall rise with healing in His wings; you shall go out and leap like stall-fed calves; you shall trample the wicked, for they shall be dust under your feet in that day which I will make, saith the Lord of hosts” (Malachi 3:17-18, Malachi 4:1-3). This is the day of judgment, which we shall discuss more fully when appropriate.
You Jews, who oppose the Son of God to your own detriment, may attempt to distort these prophetic messages for your own purposes. You wish to interpret the statements such that the nation and house of Jacob, that is, Israel, are both simultaneously called and rejected. Not in the sense of being accepted in one aspect and denied in another, but that they were all called to walk in the light of the Lord (Isaiah 2:5) and were rejected for failing to do so. Alternatively, one might consider them called in one respect and rejected in another, in such a way that there’s no division in the Lord's supper consistent with the sacrifice of Christ, meaning both the obedient and the unrighteous remain under the constraints of the same old ordinances. If you choose to interpret the matter in this manner, how then will you reconcile this with the other prophet who delivers a clear contradiction by declaring: “There is none of My favour with you, saith the Lord of hosts, and the offering out of your hands is displeasing to Me. For from the east of the sun to the west shall my name be great among the nations, and in every place they shall offer incense to My name; a pure sacrifice; great shall be My name among the nations, saith the Lord of hosts” (Malachi 1:10-11)?
