The thing is you take words that are meant and applied to Israel and apply them to non-covenant, uncircumcised, non-elect non-Hebrew Gentiles and there's your error.
That is so against the word of God. Paul left the Jews' religion, (Galatians 1:14 in which he profit in above many) and I would suggest to you to do the same. Consider:
There is no land promise for them in this world...
“And said unto him, Get thee out of thy country, and from thy kindred, and come into the land which I shall shew thee. Then came he out of the land of the Chaldaeans, and dwelt in Charran: and from thence, when his father was dead, he removed him into this land, wherein ye now dwell. And he gave him none inheritance in it, no, not so much as to set his foot on: yet he promised that he would give it to him for a possession, and to his seed after him, when as yet he had no child.”
Acts 7:3-5
“By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went. By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise: For he looked for a city which hath foundations, whose builder and maker is God…. These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they
were strangers and pilgrims on the earth. For they that say such things declare plainly that
they seek a country. And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned. But now
they desire a better country, that is,
an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.”
Hebrews 11:8-16
What about an innumerable family?
“And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood
out of every kindred, and tongue, and people, and nation; And hast made us unto our God kings and priests: and we shall reign on the earth.”
Revelation 5:9-10
“After this I beheld, and, lo, a great multitude, which no man could number,
of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.”
Revelation 7:9-10
What about taking their enemies’ gate?
“And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.”
Matthew 16:18
“But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you. When a strong man armed keepeth his palace, his goods are in peace: But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armour wherein he trusted, and divideth his spoils.”
Luke 11:21-22
“For he must reign, till he hath put all enemies under his feet. The last enemy that shall be
destroyed is death.”
I Corinthians 15:25-26
“Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.”
Colossians 2:14-15
What about blessings on all the nations of the earth?
“By whom we have received grace and apostleship, for obedience
to the faith among all nations, for
his name:”
Romans 1:5
“But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known
to all nations for the obedience of faith:”
Romans 16:26
“And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying,
In thee shall
all nations be blessed.”
Galatians 3:8
“And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation; And hast made us unto our God kings and priests: and we shall reign on the earth.”
Revelation 5:9-10
But what about Jerusalem?
“For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children. But Jerusalem which is above is free, which is the mother of us all.”
Galatians 4:25-26
“For he looked for a city which hath foundations, whose builder and maker is God.”
Hebrews 11:10
“But ye are come unto mount Sion, and unto
the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,”
Hebrews 12:22
“For here have we no continuing city, but we seek one to come.”
Hebrews 13:14
Are only some Israelites the seed of Abraham?
“Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile!”
John 1:47
“Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.”
Romans 9:6-8
“And
as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God.”
Galatians 6:16
Are only some Jews the seed of Abraham?
“They answered and said unto him, Abraham is our father. Jesus saith unto them,
If ye were Abraham’s children, ye would do the works of Abraham.”
John 8:39
“For he is
not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
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.”
Romans 2:28-29
“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.”
Revelation 2:9
“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.”
Revelation 3:9
So Israel is a spiritual nation of elect Jews and Gentiles?
“Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name. And to this agree the words of the prophets; as it is written, After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up: That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things. Known unto God are all his works from the beginning of the world.”
Acts 15:14-18
“But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.”
I Peter 2:9-10
You must interpret the Hebrew Scripture with a Hebrew mindset not with a Gentile mindset
We must interpret scriptures with the mind of Christ, not with the mind of the Jews' rellgion.
1st Corinthians 2:16
“For who hath known the mind of the Lord, that he may instruct him? But
we have the mind of Christ.” You said:
"Gentiles are not part of the covenants of God"..... yet so many scriptures said otherwise, for now, here's one.
Ephesians 3:6
“That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:”
Jeremiah, you are badly deceived, and laboring to deceive others.
