Christ died for all.
Hebrews 2:9 (LEB) — 9 but we see Jesus, for a short time made lower than the angels, because of the suffering of death crowned with glory and honor, so that apart from God he might taste death on behalf of everyone.
Israel is central to the whole of Scripture, and when I say "Scripture" I am referring to the Law, the Psalms, and the Prophets. AND in these Scriptures Israel is the central actors in relation to their three covenants of salvation with God. The first being the Abraham Covenant which according to Scripture is between God, Abram the Hebrew (Gen. 14:13), and Abram's Hebrew seed, a people later to be called the children of Jacob - who was the third patriarch in Abram's family with his father born of two Hebrew parents named Isaac, who was also himself born of two Hebrew parents, Abram and Sarai (Gen. 17.)
The New Testament writings are NOT prophecies of the Hebrew prophets, but are a majority of letters by Jewish Christians who were born-again by the Holy Spirit of Promise PROMISED TO ISRAEL by the prophet Joel in chapter 2 of his "book" of prophecies concerning Israel who was prophet sent by God to the two southern kingdom tribes: Judah and Benjamin.
The gospels (Matthew, Mark, Luke and John) were written to and for the Hebrew people (Israel) which documents the fulfillment of Hebrew Scripture prophecies and outright declarations by the Hebrew prophets - including Moses - that record the life and activities of this prophesied Messiah, Savior, Deliverer, and King of Israel.
The epistles or letters by several Jewish Christians who were born-again on the day of the Jewish Feast of Harvest, also known as Pentecost - the name derived from the fifty days from resurrection to this Feast and these letters are mainly born-again Hebrew men who discuss and share their understandings of the New Covenant era Israel found itself in since the day of Pentecost through reading and study of the Old Testament Hebrew Scripture.
The Revelation is a "book" authored by one of Jesus' disciples late in his life that records events prophesied to take place in the days and years before Israel's Messiah and King, Jesus Christ, returns to defeat Israel's enemies, His enemies, and God's enemies and set to sit on David's throne forever to rule as the rightful king of Israel.
Thus, the whole of what we call Bible is a record of God's acts and His dealings with one people born from Abraham who are the Elect, the Saints, the Holy Nation, the Bride and Church of the Living God.
There is no covenant in the Hebrew Scripture between God and non-covenant Gentiles and as a result of this truth, Gentiles are outside the covenants and protection and blessings of the God of Abraham and the God of Israel.
I challenge anyone to provide Scripture from the Old Testament of Law, Psalms, and Prophets that record covenant between God and Gentiles including terms of covenant and the name of this Gentile God made covenant with.
So, tell me, what is this Gentile's name everyone claims God made covenant with?
Thus, when reading and studying Scripture coming to the truth of the knowledge of the Son of God Israel is the central people and everything in Scripture is a record of God dealing with this ONE people born from Abraham, including his descendants born from Ishmael and Esau. It should also be noted that after the death of Abraham's half-sister and wife, Abraham married again and although it is not stated in Scripture, it is not beyond reason to conclude Abraham had other children through this union with a new wife.
2 Corinthians 5:15 (LEB) — 15 And he died for all, in order that those who live should no longer live for themselves, but for the one who died for them and was raised.
Christ died to and for the children of Israel who were under the Law of Moses in the desert at the time of the Tabernacle.
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5
To redeem them that were under the law, that we might receive the adoption of sons. Galatians 4:4–5.
A ransom for all, as God desires the salvation of all people
1 Timothy 2:3–6 (LEB) — 3 This is good and acceptable before God our Savior, 4 who wants all people to be saved and to come to a knowledge of the truth. 5 For there is one God and one mediator between God and human beings, the man Christ Jesus, 6 who gave himself a ransom for all, the testimony at the proper time,
Christ died for ALL Israel:
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5
To redeem them that were under the law, that we might receive the adoption of sons. Galatians 4:4–5.
26 And so
all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 27 For this is my covenant unto them, when I shall take away their sins. Romans 11:26–27.
The New Covenant:
Parties: The House of Israel (ten northern kingdom tribes), and the House of Judah (two southern kingdom tribes.) There are no non-Hebrew Gentiles named, mentioned, or included in this covenant.
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:
33 But this shall be the covenant that I will make with the house of Israel;
After those days, saith the LORD,
fI will put my law in their inward parts,
And write it in their hearts;
And will be their God,
And they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying,
Know the LORD:
For they shall all know me,
From the least of them unto the greatest of them, saith the LORD:
For I will forgive their iniquity,
And I will remember their sin no more.
Jeremiah 31:31–34.
He was therefore making propitiation for all the world's sin
1 John 2:2 (LEB) — 2 and he is the propitiation for our sins, and not for ours only, but also for the sins of the whole world.
The Greek word "kosmos" translated "world" is in context to the Hebrew people and refers to those who are in covenant with God, or the "world" of Hebrews.
Christ is therefore a savior for all the world
1 John 4:14 (LEB) — 14 And we have seen and testify that the Father has sent the Son to be the Savior of the world.
Titus 2:11 (LEB) — 11 For the grace of God has appeared, bringing salvation to all people,
1 Timothy 4:10 (LEB) — 10 For to this end we labor and suffer reproach, because we have put our hope in the living God, who is the Savior of all people, especially of believers.
As Scripture records God is shown to be a God who saves through covenant. Mainly, the Mosaic Covenant is which God commanded a mechanism through which under the sacrificial system of the Ceremonial Law an animal was slain to temporarily atone for the sins of the children of Israel. Later, God sends His own Son, a lamb of God, whom He slays as a substitutionary sacrifice to atone finally and forever in this ONE sacrifice the sins of the children of Israel under the Law.
4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
5
To redeem them that were under the law, that we might receive the adoption of sons. Galatians 4:4–5.
and
4 Who are Israelites; to whom pertaineth
the adoption,
and
the glory,
and
the covenants,
and
the giving of the law,
and
the service of God,
and
the promises;
5 Whose are the fathers,
and
of whom as concerning the flesh
Christ came,
who is over all, God blessed for ever. Amen.
Romans 9:4–5.
The passage in Romans 9:4-5 is the totality of God's salvation of the Hebrew people also known as the children of Israel.
God made NO COVENANT with non-Hebrew Gentiles.
NONE.
