In 2020 the world is full of people attempting to elevate themselves and their race by claiming to be the True Israel. The level of scriptural ignorance among people in general is almost as criminal as people teaching their own ignorance and preying on the more ignorant people.
They all believe ‘Israel’ is a race of people connected by being a descendant of Abraham and Jacob, Jacob being renamed Israel by God.
John the Baptist, upon seeing the Pharisees approaching said this right away:
Matthew 3:7 KJV
But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come?
Matthew 3:8 KJV
Bring forth therefore fruits meet for repentance:
Matthew 3:9 KJV
And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
Matthew 3:10 KJV
And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.
John is clear your ancestry matters not. God wants repentance.
The Law tells us who is Israel and who Isn’t. The law pertains to both the ‘stranger’ [GER = CONVERT] and those already in Israel:
Exodus 12:49 KJV
One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.
Numbers 15:16 KJV
One law and one manner shall be for you, and for the stranger that sojourneth with you.
In addition Jesus makes it clear who is his family. That is, who is Israel:
Matthew 12:46 KJV
While he yet talked to the people, behold, his mother and his brethren stood without, desiring to speak with him.
Matthew 12:47 KJV
Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee.
Matthew 12:48 KJV
But he answered and said unto him that told him, Who is my mother? and who are my brethren?
Matthew 12:49 KJV
And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren!
Matthew 12:50 KJV
For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
In the law, if a person violates the law, his “soul” would be “cut off” from Israel. Why is this important? Because if your physical ancestry determined if you were Israel, or not, than nothing you do or don’t do can change that. But clearly what you do has everything to do whether you are or are not Israel:
Exodus 12:15 KJV
Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
Exodus 12:19 KJV
Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.
Exodus 30:33 KJV
Whosoever compoundeth any like it, or whosoever putteth any of it upon a stranger, shall even be cut off from his people.
Exodus 31:14 KJV
Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death: for whosoever doeth any work therein, that soul shall be cut off from among his people.
Leviticus 7:20 KJV
But the soul that eateth of the flesh of the sacrifice of peace offerings, that pertain unto the LORD, having his uncleanness upon him, even that soul shall be cut off from his people.
Leviticus 7:21 KJV
Moreover the soul that shall touch any unclean thing, as the uncleanness of man, or any unclean beast, or any abominable unclean thing, and eat of the flesh of the sacrifice of peace offerings, which pertain unto the LORD, even that soul shall be cut off from his people.
Leviticus 7:25 KJV
For whosoever eateth the fat of the beast, of which men offer an offering made by fire unto the LORD, even the soul that eateth it shall be cut off from his people.
Leviticus 7:27 KJV
Whatsoever soul it be that eateth any manner of blood, even that soul shall be cut off from his people.
Leviticus 17:4 KJV
And bringeth it not unto the door of the tabernacle of the congregation, to offer an offering unto the LORD before the tabernacle of the LORD; blood shall be imputed unto that man; he hath shed blood; and that man shall be cut off from among his people:
Leviticus 17:9 KJV
And bringeth it not unto the door of the tabernacle of the congregation, to offer it unto the LORD; even that man shall be cut off from among his people.
Leviticus 19:8 KJV
Therefore every one that eateth it shall bear his iniquity, because he hath profaned the hallowed thing of the LORD: and that soul shall be cut off from among his people.
Leviticus 22:3 KJV
Say unto them, Whosoever he be of all your seed among your generations, that goeth unto the holy things, which the children of Israel hallow unto the LORD, having his uncleanness upon him, that soul shall be cut off from my presence: I am the LORD.
Numbers 15:31 KJV
Because he hath despised the word of the LORD, and hath broken his commandment, that soul shall utterly be cut off; his iniquity shall be upon him.
So when Jesus said he came here first for Israel, He did not mean the Jewish People, or any other race. He meant people who did the will of God. The Temple had been entrusted into the care of the Levites, but their handling of the Temple had caused those seeking to do the will of God to scatter. Jesus replaced their authority.
Today all Disciples of Jesus are in His family, we are Israel.
