When did the New Covenant and the Kingdom of God begin?

[jeremiah1five]

Then make sure you travel to Jerusalem at the appointed times of the year and offer the required sacrifices for your sins.

I have a "closet" for that.
When Jesus died and the "[Law] was nailed to His cross" it underwent no change but the born-again 'new man' did. Natural Olive tree Israel became spiritual Olive tree Israel when they in turn and in time became born again. Saul said, "the Law is spiritual." The Holy SPIRIT is also that Law God promised to put in their (Israel's) inner parts according to Jeremiah. Thus, the Law/Holy Spirit would no longer lead and guide (and command) Israel from without written in stone, but from within written on fleshly tables of the 'heart.' In other words, when Jesus resurrected so did the Law as well for the flesh dies but the spirit lives on and the Law is spiritual, and this was the reason the "letter killeth" but the spirit is eternal. Men who were only flesh died when the Law was applied to their unregenerate lives. But a regenerated, justified new man in Christ is eternal (as in eternal life.)
Justification is the teaching that comes from the Judge applying the Work of Christ to a person who receives the Holy Spirit of Promise PROMISED TO ISRAEL (Joel) and is declared "Not Guilty!" (of transgressing the Law.)
There is only One Mediator between God and man now just as there was One Mediator between God and man while Israel was under the Law. The high/High priest/Priest.

 

[jeremiah1five]

If you don’t respect God identifying Abraham as a Gentile, a Syrian, then you you are opposed to scripture.


Do you believe Jesus Christ as LORD; YHWH the LORD God?

Scripture please that clearly says "Abraham the/is Gentile."

 

[dwight92070]

Isaiah 42:6 Jesus was and is the New Covenant. To deny that is to deny this verse. And He was and is the Kingdom of God - first He alone was the Kingdom of God, then as He won over disciples, they too became part of the Kingdom of God.

And the Kingdom of God and the Kingdom of Heaven are synonymous. The Kingdom of Heaven is not the New Jerusalem in Revelation 21, although we who are part of the kingdom will go there.

In Matthew 19:23 Jesus refers to the "kingdom of heaven". Then in the next verse, He uses the term "kingdom of God", referring to the same kingdom. This happens in other places as well. So we know they are the same.

Scripture please that clearly says "Abraham the/is Gentile."

And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel to Abraham beforehand, saying, “In you all the nations shall be blessed.” Galatians 3:8


And you shall answer and say before the LORD your God: ‘My father was a Syrian, about to perish, and he went down to Egypt and dwelt there, few in number; and there he became a nation, great, mighty, and populous.
Deuteronomy 26:5

 

[jeremiah1five]

Isaiah 42:6 Jesus was and is the New Covenant. To deny that is to deny this verse.

6 I the LORD have called thee in righteousness,
And will hold thine hand, and will keep thee,
And give thee for a covenant of the people, for a light of the Gentiles;
Isaiah 42:6.

The LORD calls Israel in righteousness.
He that keepeth thee (Israel) shall never slumber.
It is this covenant with Israel (i.e. "of the people") shall be a light of the Gentiles (the mixed heritage Hebrews living in Gentile lands where God is soon to scatter them - Babylon - but Messiah will come and redeem Israel.)

24 For I will take you from among the heathen, and gather you out of all countries, and will bring you into your own land.
25 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
26 A new heart also will I give you, and fa new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
28 And ye shall dwell in the land that I gave to your fathers; and ye shall be my people, and I will be your God.
Ezekiel 36:24–28.

And He was and is the Kingdom of God - first He alone was the Kingdom of God, then as He won over disciples, they too became part of the Kingdom of God.

Jesus IS the kingdom of God.

And the Kingdom of God and the Kingdom of Heaven are synonymous. The Kingdom of Heaven is not the New Jerusalem in Revelation 21, although we who are part of the kingdom will go there.

Jesus, the kingdom of God is different from the kingdom of heaven, and they are NOT the same thing. The kingdom of HEAVEN is New Jerusalem coming down FROM HEAVEN.

In Matthew 19:23 Jesus refers to the "kingdom of heaven". Then in the next verse, He uses the term "kingdom of God", referring to the same kingdom. This happens in other places as well. So we know they are the same.

You need to study this more. You are definitely confused.

 

[jeremiah1five]

And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel to Abraham beforehand, saying, “In you all the nations shall be blessed.” Galatians 3:8

The "nations" that shall be blessed are the descendants of Abraham through Abraham (Israel) and the descendants through Ishmael (twelve sons), and Esau, whom Scripture says was very blessed of the Lord.
You ignore the context. Scripture says of Abraham, "in you" meaning his family/seed. "In Abraham" all his family shall be blessed.
And they were.

And you shall answer and say before the LORD your God: ‘My father was a Syrian, about to perish, and he went down to Egypt and dwelt there, few in number; and there he became a nation, great, mighty, and populous.
Deuteronomy 26:5

12 And Jacob fled into the country of Syria,
And Israel [Jacob] served for a wife, and for a wife he kept sheep.
Hosea 12:12.

It says nothing about being a descendant of any Syrian, only that as Abraham fled into Syria, so did Jacob.
David fled to Nob and Gath, where he met with the priest Ahimelech, who provided him with bread and the sword of Goliath (1 Samuel 21:1-9). Does that make David a Nobian or Gathite?
No, it doesn't. Otherwise, you will have to say David was not born a Judean but a Nobia.
You make no cents. Ha!
