Your claim is "False" (The Day Of The Lord) is a "Future Event" that takes place at the Lord's second coming as seen below (The End)
There Will Be No 1,000 Year Millennial Kingdom Upon This Earth, Jesus Christ Returns In Fire And Final Judgement, Dissolving This Existing Earth By Fire, Immediately After The Tribulation
This Existing Heaven And Earth Will Be (Replaced) By The New Heaven, Earth, Jerusalem, A New Creation, At The Return Of Jesus Christ
Yes, I agree we are awaiting the last day which the New Testament Scriptures tells us is the Day of the Lord. And I also agree there will not be another ONE thousand years upon this earth because this earth will be utterly burned up by the fire that comes down from God, preparing the way for the NHNE, and the holy city New Jerusalem coming down from heaven. Everything then will have been made new again, and the saints will live with the Lord forever, and there will be no more curse of death, no more sin, righteousness alone will dwell there.
It appears our only disagreement here is of the Day of the Lord having come already and demonstrated with power from above through the promise of the Holy Spirit entering into the hearts of the saints at Pentecost. All the Old Covenant prophets foretell of the Day of the Lord that would come has been fulfilled, is being fulfilled and will finally be complete during this Messianic Gospel age, and when the final Day of the Lord comes to an end with the returning of the Lord as Judge and time shall be no more.
All the Old Covenant prophecies of the Day of the Lord coming point to the Messiah coming to earth a man. The prophets write no only of Christ coming as Savior/Redeemer, but speak of all that will be accomplished in this TIME. Because all that is written of the Messiah will not be accomplished in ONE Day. But all will be accomplished that is written of Him in the age or these last days the prophets also write of.
You quote Malachi 3:2 but leave out vs 1 that gives us the timing for when the Day of the Lord would be ushered in with the Lord being as a refiners fire, and like fullers' soap. Malachi tells us the Day of the Lord coming will be preceded by the Lord's messenger. We know from the New Testament the one being sent to prepare the way for the Day of the Lord that would come is John-the-Baptist.
Malachi 3:1 (KJV) Behold,
I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the LORD of hosts.
Mark 1:2-3 (KJV) As it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee. The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight.
Mark 1:4 (KJV) John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins.
Psalm 46 read in context speaks of far greater things then the earth melting. The Psalm also speaks of what will be accomplished through the works of the Lord at His coming. He will be with us, as our refuge always, He shall make wars to cease unto the ends of the earth, He breaks the bow, and removes the spear. He will be exalted among the heathen, and in the earth.
Psalm 46:6-11 (KJV) The heathen raged, the kingdoms were moved: he uttered his voice, the earth melted.
The LORD of hosts is with us; the
God of Jacob is our refuge. Selah.
Come, behold the works of the LORD, what desolations he hath made in the earth. He maketh wars to cease unto the end of the earth; he breaketh the bow, and cutteth the spear in sunder; he burneth the chariot in the fire. Be still, and know that I am God:
I will be exalted among the heathen, I will be exalted in the earth. The LORD of hosts is with us; the God of Jacob
is our refuge. Selah.
Matthew 28:20 (KJV) Teaching them to observe all things whatsoever I have commanded you: and, lo,
I am with you alway, even unto the end of the world. Amen.
Galatians 1:16 (KJV) To reveal his Son in me, that
I might preach him among the heathen; immediately I conferred not with flesh and blood:
Galatians 3:8 (KJV) And the scripture, foreseeing that
God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.
Zechariah's prophesy of the Day of the Lord that comes includes much more than vs 12. When read in context we discover that during this Day of the Lord that shall come living waters shall go out from Jerusalem. That is fulfilled as the Gospel of Christ was sent out from Jerusalem promising everlasting life to all who believe. And in the Day of the Lord, He shall be King over all the earth. This too was accomplished when Christ ascended to heaven and is seated on the right hand of the Father in His Kingdom of heaven, from where He rules over His whole creation.
Zechariah 14:1 (KJV) Behold, the day of the LORD cometh, and thy spoil shall be divided in the midst of thee.
Zechariah 14:8-9 (KJV) And it shall be in that day,
that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.
And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.
Nahum's prophesy speaks not only of the destruction that shall come, but also of the feet of him that brings good tidings, and makes known the way of peace. This too is accomplished as the Word of the Lord, the Gospel of salvation goes unto all the earth.
Nahum 1:15 (KJV) Behold upon the mountains the feet of him that bringeth good tidings, that publisheth peace! O Judah, keep thy solemn feasts, perform thy vows: for the wicked shall no more pass through thee; he is utterly cut off.
Luke 2:10 (KJV) And the angel said unto them, Fear not: for,
behold, I bring you good tidings of great joy, which shall be to all people.
Romans 10:15 (KJV) And how shall they preach, except they be sent? as it is written,
How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
If we consider only what the prophets of old prophesy about the last Day of the Lord that shall come when Christ returns, then we see the Day of the Lord as bringing only wrath, judgment and destruction from the Almighty, but we altogether miss the prophesies that bring good news of the Savior Messiah who would come in His Day to save His people from their sins, and give eternal life to all who believe by grace through faith. The prophets bring good news of the Day of the Lord that would come and was fulfilled when "a child was born". The Day of the Lord is not only bad news that shall come on the final Day of the Lord that will come.
Isaiah 9:6-7 (KJV) For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counseller, The mighty God, The everlasting Father, The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.
