You are delusional. The kingdom of God is the kingdom of Heaven. The Old Covenant established a means for forgiveness of sin, but not the payment for the penalty of is (Heb 10L4).
The animal sacrifice was killed as substitutionary sacrifice for sin and you say there's no punishment for sin in the Old Testament (Law)? You are again wrong. Study the Old Testament and go forward to the New Covenant letters and gospels in order to rightly understand what the apostles are saying about their studies of the Old Testament.
And you make a mistake about what - or should I say WHO - the kingdom of God is. When Christ came He said many times "the kingdom of God" but the fact is there was no kingdom as you define His words. Israel was an occupied territory. There was no king, no land (it was occupied), no subjects, no court, no realm and the totality of Israel's laws were subjugated mostly for Roman law. But let's look at what Jesus was really saying when you take the Greek word.
28
But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.
Matthew 12:28.
Question: What is Christ doing?
Answer: He is casting out demons with the finger of God.
In saying this He is claiming to be a King and the King(dom) of God.
The Greek word is:
kingdom: [Strong's #932] βασιλεία basileia
from [#935] (basileus); properly
royalty, i.e. (abstract)
rule, or (concrete) a
realm (literal or figurative.)
as a noun feminine Jesus is stating He is the King of God.
20 And when he was demanded of the Pharisees, when the
kingdom of God should come, he answered them and said, The
kingdom of God cometh not with observation:
21 Neither shall they say, Lo here! or, lo there! for, behold, the
kingdom of God is within you.
Luke 17:20–21.
With your understanding of "kingdom" how can the traditional definition of "kingdom" as a place, a court, subjects, etc., be within a believer? That makes no sense. But Christ as a Person (third Person of the Trinity) can dwell in a believer and is "within you." Here's more. Saul understood the word:
20 For the
kingdom of God is not in word, but in
power.
1 Co 4:19–20.
Christ is the power, not the land, the court, the subjects the way you understand the translated English word and not the Greek word used.
Then there's the "kingdom of heaven." This is New Jerusalem coming down out of the sky, out of heaven:
2 And I John saw the holy city, new Jerusalem, coming down
from God out of heaven, prepared as a bride adorned for her husband. Revelation 21:2.
Sometimes the Greek word "kingdom" is used concretely and abstractly - even figuratively. You must study this in order to discern the correct rendering. But to read an English translation and use a translation to get doctrine you will fail at being correct and precise if being precise is one of your goals as a student of Christ, who is the Eternal Spirit.
Children of the Promise are neither Jew nor Greek, neither slave nor free, neither male nor female (Gal 3:28).
First, the children of promise in the Old Testament are the eventual seed or descendants of Abraham. The Abraham Promises was inherited by Isaac, Jacob after Isaac's death, and Jacob's twelve sons after Jacob's death never having the Abraham promises realized:
13 These all died in faith, not having received the promises, Hebrew 11:13.
All those in the Hall of Faith of Hebrews 11 are all Hebrew men and women. There is NOT a non-Hebrew Gentile among any of them (except those born before Eber.)
So, the original identification is the Hebrew people as children of (the Abraham) promise(s). Saul, as rabbi and Pharisee know this. He will not violate Old Testament Scripture identifications and change them to apply to non-Hebrew Gentiles. None of the rabbi's and Pharisees, nor even the Sadducees or the Essenes have ever interpreted "children of promise" as anyone other than Hebrews/Jews. So, when Saul says:
28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29 And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise. Galatians 3:28–29.
He is referring to Hebrews who are the children or seed of Abraham for the promises of Abraham was at death of the Patriarchs and the sons (12 tribes) inheritors of the Abraham Promises (covenant.) The use of "Greek ["Hellens"] refer to Jews who grew up in Gentile lands as the Diaspora (Exiles) heavily under the cultural influence of Greek culture. They are identified extensively in the New Covenant writings from Matthew to Revelation and never refer to non-Hebrew Gentiles. They were most used of mixed heritage Hebrews of Gentile descent.
Gal 1:2 and all the brothers who are with me, To the churches of Galatia:
Gal 4:28 Now you, brothers, like Isaac, are children of promise.
Brothers -- Mostly Gentiles, some Jews. Paul was the apostle to the Gentiles (Eph 3:1-13); they are his brothers.
To be a "brother" one must have the same father. In referring to Isaac and Saul calling his readers of his letters "brothers" he is addressing Hebrews, NOT Gentiles. It is your interpretation that is in error. Saul is apostle of mixed heritage Jews who were of the Diaspora (Exiled) and grew up in Gentile lands heavily influenced for 29-35 generations with Greek culture, the Greek culture left behind by Alexander the Great. There is much that YOU NEED to study of Biblical text and world history. I am a 4.0 student of both. But let's look deeper at Saul's Galatian letter to see WHO he was addressing as recipients of his letter: Hebrews/Jews or non-Hebrew Gentiles:
5 He therefore that ministereth to you the Spirit, and worketh miracles among you, doeth he it by the
works of the law, or by the hearing of faith?
6 Even as Abraham believed God, and it was accounted to him for righteousness.
7 Know ye therefore that they which are of faith, the same are the
children of Abraham.
8 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.
9 So then they which be of faith are blessed with
faithful Abraham.
10 For as many as are of the
works of the law are under the curse:
for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
11 But that no man is justified
by the law in the sight of God, it is evident: for, The just shall live by faith.
12 And the
law is not of faith: but, The man that doeth them shall live in them.
13 Christ hath redeemed us from the curse of the
law, being made a curse for us:
for it is written, Cursed is every one that hangeth on a tree:
14 That the
blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive
the promise of the Spirit through faith.
15
Brethren, I speak after the manner of men; Though it be but a man’s covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.
16
Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
17 And this I say, that
the covenant, that was confirmed before of God
in Christ,
the law, which was four hundred and thirty years after, cannot disannul, that it should make the
promise of none effect.
18 For
if the inheritance be of the law, it is no more of promise: but God gave it to
Abraham by promise.
19 Wherefore then serveth
the law? It was added because of transgressions, till the seed should come to whom the
promise was made; and it was
ordained by angels in the hand of a mediator.
20 Now a
mediator is not a mediator of one, but
God is one.
21 Is
the law then against the
promises of God? God forbid: for if there had been a
law given which could have given life, verily
righteousness should have been
by the law.
22 But the
scripture hath concluded all under sin, that the promise by
faith of Jesus Christ might be given to them that believe.
23 But before faith came, we were
kept under the law, shut up unto the faith which should afterwards be revealed.
24 Wherefore
the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
25 But after that faith is come, we are no longer under
a schoolmaster.
26 For ye are all the
children of God by faith in Christ Jesus.
Galatians 3:5–26.
all the boldfaced are Hebrew ideas and concepts and terms that are understood by Hebrews. Gentiles had thousands of gods. They were NEVER under a schoolmaster (THE LAW) so why do YOU put them under the Law? That's ADDING to the Bible. The "SPIRIT OF PROMISE" the "HEATHEN" and all these words are understood by Jews NOT GENTILES. Gentiles knew almost NOTHING of the Hebrew religion of the Mosaic Law. They wouldn't understand these Hebrew Scripture terms. So, why do you give them the magical understanding as experts of the Hebrew religion when they were OUTSIDE the Hebrew religion and the Law of Moses???
As I said, you interpret the English translation of the Hebrew Scripture like a Gentile, assigning Gentile definitions and understandings to Hebrew terms, ideas and concepts that are easily understood by a Hebrew mind, the very mind and audience Saul was writing to. You should have "got this" when Saul said, The Law was OUR schoolmaster" meaning "our" refers to Jews.
My God, don't you see the infection of false Constantinian Gentile theology you've been indoctrinated with in your education and study? Your Gentile-authored theology books are rife with misinterpreting Hebrew terms with a Gentile mindset.
Don't you see this? Are you so blinded?
What a damn shame you don't. Open your eyes, fool. Yo are in grave error and just may be in danger of damnation for seeing the One True God as lies.
