I agree......but think of whom were being addressed in Matthew's gospel. Were they not included in the "everyone"? Because I wholeheartedly believe they were!
It all began with the Hebrews. Israel was meant to be a "city on a hill" where God was glorified ALL throughout the world by the devotion His people were supposed to display (that was the plan - but obviously God knew how that was going to play out).
The gentiles were never meant to be excluded, though....in fact, look at what Jesus had said while He was cleansing the temple:
Mark 11:17 ~ "Has it not been written: 'My house will be called a house of prayer for all the nations'?
Something else to keep in mind: the entire world population was one in kind prior to the call of Abraham. He was the first to be designated a Hebrew (Genesis 14:13). The Hebrews were not set apart as a distinct people until the giving of the law of Moses (Exodus 19:5-6; cf. Ephesians 2:14).
So what was the covenant God made with Abraham (Genesis 17)? Did that not include EVERYONE? Remember.....that is called an "everlasting covenant" (it was unilateral....God shouldered ALL responsibility)....so, the way I see it, that covenant NEVER ended and never will .
Galatians 3:16 ~ Now the promises were spoken to Abraham and to his seed. He does not say "and to seeds," as though referring to many, but referring to one, and to your seed, who is Christ.
Acts 3:25 ~ And you are sons of the prophets and of the covenant God made with your fathers, when He said to Abraham, 'Through your offspring all the families of the earth will be blessed.'
Another key is to understand what's then meant by "Israel". Israel means "God's people" or "His church".......and after the Sinai covenant was broken (at Christ's death - because a bilateral covenant cannot remain in effect when one party is dead)...."Israel" then became all His faithful followers (His people, His church).
"....this is the new covenant I will make with the people of Israel [His church] on that day. I will put my law in their minds, and I will write them on their hearts. I will be their God, and they will be my people’” (Jeremiah 31:31, 33)
"You are the light of the world--like a city on a hilltop that cannot be hidden. ~ Matthew 5:14
The difference between the two covenants in Jeremiah 31:31 and Matthew 26:28.
The covenant in
Matthew 26:28 was made for everyone. Christ's blood saves all mankind, Jews and gentiles, from sin, and not solely the Jewish people of Israel and Judah.
Matthew 26:28 King James Version (KJV)
For this is my blood of the new testament, which is shed
for many for the remission of sins.
The covenant in
Jeremiah 31:31 is made only with the Jewish people, not everyone.
Jeremiah 31:31 King James Version (KJV)
Behold, the days come, saith the Lord, that I will make a new covenant
with the house of Israel, and with the house of Judah:
The covenant of Jeremiah 31 is a promise solely to the remnant of Israel and Judah that will be fulfilled at the end of the tribulation fulfilling the prophecy of the Time of Jacob's Trouble. In other words, Jacob is not a representation of the world, all prophesies concerning Jacob are about Israel. In bible prophecies, Jacob represents Israel, all of Israel, both kingdoms, not the world.
The prophecy begins at the beginning of Jeremiah 30 and ends at the end of chapter 31 with a promise fulfilled by God, His covenant He made thousands of years solely to the Jewish people (Jacob) in Jeremiah 31:31.
Jeremiah 30:5-7 is about Israel, not the world.
Jeremiah 30:5-7 King James Version (KJV)
5 For thus saith the Lord; We have heard a voice of trembling, of fear, and not of peace.
6 Ask ye now, and see whether a man doth travail with child? wherefore do I see every man with his hands on his loins, as a woman in travail, and all faces are turned into paleness?
7 Alas! for that day is great, so that none is like it: it is even the time of Jacob's trouble, but he shall be saved out of it.
Jeremiah 30:8-9 is about Israel, not the world.
Jeremiah 30:8-9 King James Version (KJV)
8 For it shall come to pass in that day, saith the Lord of hosts, that I will break his yoke from off thy neck, and will burst thy bonds, and strangers shall no more serve themselves of him:
9 But they shall serve the Lord their God, and David their king, whom I will raise up unto them.
Jeremiah 30:11 is about Israel, not the world.
Jeremiah 30:11 King James Version (KJV)
11 For I am with thee, saith the Lord, yet I will not make a full to save thee: though I make a full end of all nations whither I have scattered thee, end of thee: but I will correct thee in measure, and will not leave thee altogether unpunished.
Jeremiah 30:18 is about Israel, not the world.
Jeremiah 30:18 King James Version (KJV)
18 Thus saith the Lord; Behold, I will bring again the captivity of Jacob's tents, and have mercy on his dwelling places; and the city shall be builded upon her own heap, and the palace shall remain after the manner thereof.
Jeremiah 30:23-24 is about the end times, the tribulation, Daniel's 70th week. Anytime you see the words "latter days" in the bible, it implies the coming tribulation, not the time of the first coming where the covenant of Matthew 26:28 was performed. It means this is prophecy of the end times.
Jeremiah 30:23-24 King James Version (KJV)
23 Behold, the whirlwind of the Lord goeth forth with fury, a continuing whirlwind: it shall fall with pain upon the head of the wicked.
24 The fierce anger of the Lord shall not return, until he hath done it, and until he have performed the intents of his heart: in the latter days ye shall consider it.
Jeremiah 31:1-2 is about Israel, not the world.
Jeremiah 31:1-2 King James Version (KJV)
1 At the same time, saith the Lord, will I be the God of all the families of Israel, and they shall be my people.
2 Thus saith the Lord, The people which were left of the sword found grace in the wilderness; even Israel, when I went to cause him to rest.
Jeremiah 31:4-5 is about Israel, not the world.
Jeremiah 31:4-5 King James Version (KJV)
4 Again I will build thee, and thou shalt be built, O virgin of Israel: thou shalt again be adorned with thy tabrets, and shalt go forth in the dances of them that make merry.
5 Thou shalt yet plant vines upon the mountains of Samaria: the planters shall plant, and shall eat them as common things.
Jeremiah 31:7-11 is about Israel, not the world.
Jeremiah 31:7-11 King James Version (KJV)
7 For thus saith the Lord; Sing with gladness for Jacob, and shout among the chief of the nations: publish ye, praise ye, and say, O Lord, save thy people, the remnant of Israel.
8 Behold, I will bring them from the north country, and gather them from the coasts of the earth, and with them the blind and the lame, the woman with child and her that travaileth with child together: a great company shall return thither.
9 They shall come with weeping, and with supplications will I lead them: I will cause them to walk by the rivers of waters in a straight way, wherein they shall not stumble: for I am a father to Israel, and Ephraim is my firstborn.
10 Hear the word of the Lord, O ye nations, and declare it in the isles afar off, and say, He that scattered Israel will gather him, and keep him, as a shepherd doth his flock.
11 For the Lord hath redeemed Jacob, and ransomed him from the hand of him that was stronger than he.
Jeremiah 31:18-21 is about Israel, not the world.
Jeremiah 31:18-21 King James Version (KJV)
18 I have surely heard Ephraim bemoaning himself thus; Thou hast chastised me, and I was chastised, as a bullock unaccustomed to the yoke: turn thou me, and I shall be turned; for thou art the Lord my God.
19 Surely after that I was turned, I repented; and after that I was instructed, I smote upon my thigh: I was ashamed, yea, even confounded, because I did bear the reproach of my youth.
20 Is Ephraim my dear son? is he a pleasant child? for since I spake against him, I do earnestly remember him still: therefore my bowels are troubled for him; I will surely have mercy upon him, saith the Lord.
21 Set thee up waymarks, make thee high heaps: set thine heart toward the highway, even the way which thou wentest: turn again, O virgin of Israel, turn again to these thy cities.
Jeremiah 31:31-32 is about Israel, not the world.
Jeremiah 31:31-32 King James Version (KJV)
31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
Every single verse throughout chapters 30 to 31, are prophecies solely about Israel, not the world. How do you come to the conclusion the covenant in verse 31 applies to the world when everything in this prophecy is solely about Israel?
I'm sure if you read and accept the bible for what it said, things wouldn't be so complicated. Why don't you give that some practice.
