I have no problem with what plans God has with all believers. Here are several prominent believers for whom the Bible had no trace of Israelite heritage whatsoever:
Jethro – The father-in-law of Moses was a Midianite priest.
Rahab – She was an Amorite living in Jericho.
Ruth – She was a Moabite.
Luke – He was Syrian Greek.
Cornelius – He was a Roman centurion who converted to Christianity.
Philemon – He was a slave owning Gentile who converted to Christianity.
Let's not forget Noah and Adam or Seth and the others.
Paul never got your memo that he should preach to only those who have at least a gram of Israelite blood in them. You must have forgotten to send out that memo.
Saul was a rabbi and Pharisee. He taught the Hebrew Scripture. The Hebrew Scripture records no covenant between God and non-Hebrew Gentiles and neither did Saul of the apostles teach salvation to non-Hebrew people because the basis of salvation is covenant, and Gentiles had none. The animal sacrifices were sacrificed to atone for the sins of the children of Israel and Jesus, as lamb of God, fulfilled the Law where the sacrifice is concerned. Jesus as substitute for the animal sacrifice died to atone for the sins of the children of Israel according to the Law. You remember the verse how Jesus died according to the Scripture (Law of Moses), right?
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
This is the good news (gospel) found in the Hebrew Scripture after Saul disappeared after meeting Israel's Kinsman-Redeemer for 14-17 years to study what the Scripture revealed after the advent of the Holy Spirit of Promise PROMISED TO ISRAEL. So yes, Saul taught the animal sacrificed to atone temporarily the sins of the children of Israel was substituted by Jesus who died to atone for the sins of the children of Israel. That's why everyone who says Jesus fulfilled the Law is correct even though they don't fully understand what it truly means.
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
SEE ABOVE.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
According to the Scripture regarding the animal sacrifice on Yom Kippur which for one year atoned for the sins of the children of Israel until Jesus came and died finally and eternally for the sins of the children of Israel. THAT is the good news found in the Scripture Saul taught.
4 And that he was buried, and that he rose again the third day according to the scriptures:
Now he gets into the prophets and the things they prophesied about Jesus, such as the casting lots for His garments, being crucified on a tree, etc.
5 And that he was seen of Cephas, then of the twelve:
Post-resurrection events.
6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
Five hundred brethren meaning Jews - NO GENTILES - to whom Israel's Messiah appeared. Again, Jesus did not appear to Gentiles. He wasn't their Savior, Lord, or King. He is King OF THE JEWS!
7 After that, he was seen of James; then of all the apostles.
Jimmy boy, Jesus' half-brother, similar to Samaritans who were also half-brethren to the Jews being offspring of Jew-Assyrian parents.
8 And last of all he was seen of me also, as of one born out of due time.
1 Corinthians 15:1–8.
One Jew to another, or should I say, one Jew to a Benjaminite. Still, Jesus was prophesied by Moses who would be born from one of the twelve tribes in order to save the twelve tribes - Abraham included.
Paul is speaking about Israel and non-Israel. All of non-Israel, the world over, has been given the name Gentiles. There is no 3rd group in the entire world. Maybe there's a 3rd life form in a distant planet.
Jesus is King of the Jews. See above.
Israelite Jews were expelled from Rome at the time of Paul's writing. So the demarcation between Israel and non-Israel was pretty clear.
But Jews of mixed heritage remained since their mixed heritage assisted their surviving such persecution just as Saul Roman citizenship helped him when he needed it, too. The Jewish Church at Rome was founded by Hebrews who participated in the Feast of Harvest when the Holy Spirit of Promise PROMISED TO ISRAEL arrived and three thousand Jews - no Gentiles - were born again.
10 Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and
strangers of Rome, Jews and proselytes,
11 Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God.
Acts 2:10–11.
Moses prophesied that God would send a Deliverer to deliver the children of Israel from their sin. Jesus fulfilled that prophecy and died according to the Law of Moses in which God ordained the animal sacrifices and sent His own Son to die a substitutionary death in place of the animal to atone for the sins of the children of Israel according to Scripture. God saves through covenant and non-Hebrew Gentiles do not have a covenant with God. God chose one family ABOVE all families of the earth to call His own.
Remember. Jesus died according to the Scripture (Law, Psalms, and the Prophets) which Scripture was given to and for the children of Israel in covenant with God. Let's not break Scripture. The LORD said that it was impossible to do despite your Gentile-leaning interpretations.
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. Gal. 4:4–5.
Stop contradicting God's Word. Jesus is a Hebrew Messiah sent to redeem the Hebrews and the way God did that is through covenant.
Your Ethnic Cleansing spirit's feeble attempt to redefine words and nations will not work.
Pay attention:
15 The LORD thy God will raise up unto thee a Prophet
from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken; Deut. 18:15.
18 I will raise them up a Prophet
from among their brethren, like unto thee, and will put my words in his mouth; and
he shall speak unto them all that I shall command him. Deut. 18:18.
"
Them" are identified as the children of Israel. "
Them" are NOT non-Hebrew Gentiles. Jesus said it most succinctly when He said:
24 But he answered and said,
I am not sent but unto the lost sheep of the house of Israel. Mt 15:24.
The New Covenant is between God and the House of Israel (and Judah.)
Non-Hebrew Gentiles need not apply. It's a salvation OF THE JEWS just as Jesus said.
So, stop contradicting Scripture. True born of God Christians don't do that.
So, stop with your erroneous interpretation of Scripture. Jesus died to atone finally and eternally for the sins of the children of Israel and ONLY the children of Israel who is a child of Isaac who is a child of Abraham and through whom the inheritance rests. SALVATION IS OF THE JEWS.
Not Gentiles.
