True. But the "seed" you speak of are the seed [as many] of Israel, correct?
However, note that Paul said "seed" and NOT as many or all. Galatians 3:16 reads:
"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 [singular], which is Christ."
Furthermore, as a nation, Israel will NEVER recognize Jesus as the Messiah.
It is Only Israel in fact that only truly recognises Jesus Christ in fact !
One must have a handle on what Israel means !
Now one should look to the Bible for such a handle on the real issue of Israel, but the worldly only know this world, so they claim that it's the Land that is Israel ? But the Bible and the Holy Spirit is another thing as to ones worldly point of view.
The Bible first talks about one man who becomes Israel ? funny that all religions nowadays will run about freaking out to shut anyone up on this subject ?
They do not want you to know who Jacob really is or who or why he became in fact !
So you will not have a handle on the reality of the gravity on the subject that is truly at hand ? because it all kicks off with why Jacob became Israel !
This is the key point that all should understand in fact, because if you don't you could be mislead ?
Not to mention the next time that one is called Israel, is with a dude called Nathaniel in fact and this must be understood by anyone who is worthy of being a born again Christian ?
Yes Nathaniel is a Key point that must be understood !
Now it was Jesus who said of him that he was a true Israelite in fact !
Ok so we have 2 only people that one was called Israel by a Angel ? and the next is called such by Jesus ? how interesting !
Now one must understand all that the Bible says that Jesus says to Nathaniel ! Look it all up ! such a most interesting subject in the Bible, because it's a Key point that any worthy Christian should understand, but the carnal religious would not understand the issue and just dismiss Nathaniel in all this and also they would not have a clue what or why Jesus called him Israel !
So you see the religious will not serve God at all, they never did, because they do not know God ! they serve this world and it's gods for they are under delusions and deceptions of this world.
Christ Jesus calls people out of this world in fact and into the Kingdom of God !
The Kingdom of God is Israel and the key point in understanding this is with starting to understand why Jacob was given the name Israel and who Nathaniel was given the name, then you may understand God in reading the Bible.
So who is it that wants to lead you to believe in this world ? with total nonsense like Israel is a worldly State ?
One must understand why God gave the Jews the Law and who was to come ? Grace is the Key the Kingdom of God for all. for without the Biblical understanding of Grace, no one can help you or this world in fact. Jesus came and gave all that we need, but one must pick it up ! and hold it up high ! such is the most important thing in ones life above all ! That's Christ Jesus ! We live and breath Christ Jesus ! That's is what being a true Israelite is all about !
Jesus said of Nathaniel what was to be seen ? why did Jesus say such to him ? well he knew that he was worthy of a true Israelite in fact ! Jesus said so ! So it's a outright Fact that must be taken totally seriously. It's a major issue that is a Key on the subject of what is Israel in fact.
