This passage emphasizes that ethnicity or bloodline does not determine God's chosen people or their standing with Him. Our Lord and the apostles taught that true worship and being part of God's people are matters of the heart, faith, and obedience, not ethnicity. Examples from scripture show that God's grace was extended beyond Israel to Gentiles, and that many Israelites who relied solely on their bloodline or outward appearances were rejected by God. The Bible highlights that being a "Jew" is about inward faith and relationship with God, not ethnicity. Ultimately, God's promise and His people are defined by faith in Yeshua (Jesus), not racial or bloodline distinctions.

    What does our Lord say about ethnicity and Jews? Our Lord speaking;

 And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read..Luk 4:16

But I tell you of a truth, many widows were in Israel in the days of Elias, when the heaven was shut up three years and six months, when great famine was throughout all the land; Luk 4:25
But unto none of them was Elias sent, save unto Sarepta, a city of Sidon, unto a woman that was a widow. Luk 4:26
 And many lepers were in Israel in the time of Eliseus the prophet; and none of them was cleansed, saving Naaman the Syrian. Luk 4:27
And all they in the synagogue, when they heard these things, were filled with wrath, Luk 4:28
And rose up, and thrust him out of the city, and led him unto the brow of the hill whereon their city was built, that they might cast him down headlong. Luk 4:29

    They thought God was partial to them because of their bloodline, but He showed them that was not the case, and it made them mad.
That has never been the case. Even at Mount Sinai the only ones who survived were those whose heart was right with Him. Later, in the wilderness the same thing happened. Only those whose heart was right with Him lived to cross the Jordan river, only two out of the original million or so.

    Still today, The Lord has not changed His religion. When speaking with the woman at Jacob's well, He said;

Ye worship ye know not what: we know what we worship: for salvation is of the Jews. Joh 4:22
But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. Joh 4:23

    Not long after that, the apostle Paul explained the new deal clearly, he said;

For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh: Rom 2:28
 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God. Rom 2:29

    How could people distinguish between the two? It must have looked like nothing had changed to most of the people in those days. While teaching in the temple the chief priests and elders came to Him to find out what authority He claimed to have. He gave them some examples of how things looked from God's view point and declared;

Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. Mat 21:43
 And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder. Mat 21:44
And when the chief priests and Pharisees had heard his parables, they perceived that he spake of them. Mat 21:45
But when they sought to lay hands on him, they feared the multitude, because they took him for a prophet. Mat 21:46

    Every time He made them mad they tried to kill Him, instead of accepting who He is and being forgiven.

    According to God, this problem existed in the wilderness, as He explained in those days;

Forty years long was I grieved with this generation, and said, It is a people that do err in their heart, and they have not known my ways: Psa 95:10
Unto whom I sware in my wrath that they should not enter into my rest. Psa 95:11

    That means they will not show up in heaven. That's pretty serious. Yet even today, many still believe in an ethnic empire that God never promised. He did promise Abraham his children would be a great nation, but He promised the same to Ishmael.

    The last thing the most high God said about ethnic Israel was;

And unto the angel of the church in Smyrna write; These things saith the first and the last, which was dead, and is alive; Rev 2:8
I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan. Rev 2:9
And to the angel of the church in Philadelphia write... Rev 3:7
I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name. Rev 3:8
Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee. Rev 3:9

    Think about this; If being a Jew had anything to do with bloodline, What difference would it make what they said? Jews would still be Jews and Gentiles would still be Gentiles. Clearly, God is defining His people as something other than an ethnic bloodline.

    Once again Paul expressed it best;

     For the promise, that he should be the heir of the world, was not to Abraham, or to his seed, through the law, but through the righteousness of faith. Rom 4:13

    When we think of who is a Jew try not to get hung up on the ethnic group God choose to marry. He could have chosen a different group. The point is not the skin  color, it is the relationship and the behavior toward God that makes us Jews.

    The fact is, everyone born on earth is a Gentile until they are saved by faith and baptized to the Savior, Yeshua Ha Mashiach. Since He is now king of the universe, it will now be His way forever.
