I do not mean to offend, I hope you will feel the same way.
Will you take the time to read the following and see if you might understand that absolutely everything in the Bible is about Jesus.
It is written about Him.
Paul is discussing a lot in Galatians, but he covers the Promises, plural, and applies ALL the Promises (no matter the Covenant) to the Beneficiary, Jesus. The Promises of the Testament (Will), are only for those who will inherit what is in it.
The New Testament changes terms in the greek; the "Land" promise becomes a universal term
Brethren, I speak in terms of human relations: even though it is only a man's covenant, yet when it has been ratified, no one sets it aside or adds conditions to it. - Galatians 3:15 NASB
"When a man writes his last will and testament, he puts within that will his wishes as to what is to be done with his estate. Among other things, he specifies who are to be the beneficiaries. He is under no obligation to include them in the will, and the inheritance is not compensation for what the beneficiaries have done. The fact, nevertheless, is that if they are named in this will, then they are to receive the inheritance.
Paul notes here that even in the case of a human will, once it has been confirmed or validated, the terms therein cannot be altered. After the death of the testator, its instructions must be carried out in every detail. The implication is that the testament of God, who is infinitely more trustworthy than man, is all the more dependable and unchangeable. Paul sets this up as an illustration of why the Mosaic law must not be interpreted as an annulment or alteration of the terms of the Abrahamic covenant.
The point is that nothing which came after this legal arrangement with Abraham would change the original covenant that God made with him. Both the Gentile Christians in Galatia along with the Judaizers would have understood this illustration. They would have concluded that the blessing, which was given to Abraham by God, was received by Abraham by faith as he believed in the promises of God.
This "irrevocable trust agreement" that God made with Abraham is described in terms of the beneficiary of the trust (v. 16), the date of the trust (v. 17), and the condition for inheritance (v. 18).
Our study of these terms of the Abrahamic covenant will enable us to appreciate the gracious, unconditional nature of God's love for us.
The Beneficiary of the Trust
Galatians 3:16 (NASB) Now the promises were spoken to Abraham and to his seed. He does not say, "And to seeds," as referring to many, but rather to one, "And to your seed," that is, Christ.
Now, as to the promises given to Abraham, the Judaizers would argue that they were only given to Israel since they were the seed or descendants of Abraham. Therefore, since Abraham was later instructed by God to be circumcised, along with his family, the Judaizers' reasoning was that to be a true Christian, who has accepted the Messiah who came through the Jews, everyone must be circumcised to lock in their salvation.
Following that line of argument, Paul says, "God specified in His will that the beneficiaries were to be Abraham and his seed." The apostle calls particular attention to the word "seed," as distinguished from "seeds." And that singular seed that God had in Christ, not all the blood descendants of Abraham....
...Paul is saying that the primary recipients of the Abrahamic covenant were Abraham and Christ. This, of course, would include all who are in Christ - believers. This promise is not realized in the Jews, but Christians.
...Genesis 15:18 (NASB) On that day the LORD made a covenant with Abram, saying, "To your descendants I have given this land, From the river of Egypt as far as the great river, the river Euphrates:
By quoting the specific geographic boundaries that Abram's descendants will inherit, God makes it plain that Abraham's physical descendants will reap the benefit of this covenant. Israel will inherit real land. But their inheritance of the land was only a type....
...We have to realize that Paul's definition of seed contradicts the Jewish nationalistic interpretation of this term. Jews were convinced that the term seed referred to the physical descendants of Abraham, the Jewish people. Therefore, they believed it was absolutely necessary to belong to the Jewish nation in order to receive the blessings promised to Abraham.
Paul is just as exclusive as his Jewish counterparts, but his exclusivity is not based on ethnic identity. Since Christ is the heir of the promises, all those, and only those, who are in Christ by faith are beneficiaries of the irrevocable trust agreement God made with Abraham:
And if you belong to Christ, then you are Abraham's offspring, heirs according to promise - Galatians 3:29
When God established the covenant with Abraham in Genesis 12 and then expanded upon it in Genesis 15 and 17, what was Abraham thinking? What did he understand? What sort of fulfillment was Abraham looking forward to when he was given the word of promise concerning the land? What did he expect? Did he look for an earthly fulfillment? Did Abraham just see the type or did he see past the type to the anti-type? According to God's Word in the book of Hebrews, Abraham was looking past the type to the anti-type, he was looking for a heavenly city:
By faith he [Abraham] lived as an alien in the land of promise, as in a foreign land, dwelling in tents with Isaac and Jacob, fellow heirs of the same promise; 10 for he was looking for the city which has foundations, whose architect and builder is God. - Hebrews 11:9-10
By faith he dwelt in the land of promise. By faith in God's promise of a heavenly city he lived as a pilgrim on the earth. He knew the earth wasn't his home, so he never tried to make it his home. The city Abraham was looking for was the heavenly Jerusalem. The writer relates:
But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to myriads of angels, 23 to the general assembly and church of the first-born who are enrolled in heaven, and to God, the Judge of all, and to the spirits of righteous men made perfect, - Hebrews 12:22-23
From these verses we can see the different description of the same entity; the city, the kingdom, the heavenly Jerusalem, the church, and Mount Zion. These all have their fulfillment in the New Covenant as established in the first century. This was in contrast to the old, physical, earthly city of Jerusalem."
Berean Bible Church
With all due respect, I'm afraid you are making the same mistake the 1st Century Jews made - not understanding that the Land Promise was a temporary type only.
"The Date of the Trust
What I am saying is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise. - Galatians 3:17
So 430 years after the Abrahamic Covenant was given, an additional arrangement was instituted by God. This time God made an agreement, not a promise, with Israel. This agreement demanded certain responsibilities of each party to the agreement. There were consequences involved, and each side had to uphold its part. But that agreement was made at a much later time than the promise, that was given to Abraham, thus it could have no effect on that promise. The promise and the agreement cannot be mixed together with one another, because they accomplish different results. Thus, the fact that the Law came later cannot invalidate the great, life-giving promise that was given originally. That is the argument of these verses.
The Mosiac covenant does not invalidate the Abrahamic covenant - God's promises in the Abrahamic covenant still stand.
The Condition for Inheritance
For if the inheritance is based on law, it is no longer based on a promise; but God has granted it to Abraham by means of a promise. Galatians 3:18
"The Law" here is a reference to the Mosaic covenant. This was not a promise, but an agreement:
'Now then, if you will indeed obey My voice and keep My covenant, then you shall be My own possession among all the peoples, for all the earth is Mine; Exodus 19:5
Have God's promises to Abraham been fully fulfilled? Those theologians who are yet looking for a golden age for national Israel do not think so. But Paul makes it abundantly clear that the promised descendant of Abraham is Christ. And it is through Christ, through faith in His subsitutional death that people from all nations will be blessed."
Berean Bible Church
Again, with all due respect, Peter, who was Jewish, never said Jews or anyone else should look for, or would receive anything other than this:
But in keeping with his promise we are looking forward to a new heaven and a new earth, the home of righteousness. - 2 Peter 3:13
Peter even connects it to the Promise. Why didn't Peter say, "in keeping with his promise we are looking forward to a restored Judea, Jerusalem and inheriting the Land in the Middle East" He didn't say anything like that, though he should have is what you believe is true.
