AS  believer we are told to  “study”. But our studying must not remove the “Holy Spirit” who come to lead us into all truth. There are two sides to every coin, two sides to every argument, but only one is true. Most people make the mistake in using the word “Jews” to refer to all Israel. This is the Basic error in their argument, and from then everything is base on an erroneous foundation.

Jacob’s name was change to “Israel” as you rightly said. Now Jacob had 12 sons who were given the name Israel as a Nation. Both King David and Solomon rule that 12 tribe nation . I will only refer the scriptures so you can read the. Exodus 28v21,39v14 Matt19v28. 2 Kings v
20  And it came to pass, when all Israel heard that Jeroboam was come again, that they sent and called him unto the congregation, and made him king over all Israel: there was none that followed the house of David, but the tribe of Judah only.  21  And when Rehoboam was come to Jerusalem, he assembled all the house of Judah, with the tribe of Benjamin, an hundred and fourscore thousand chosen men, which were warriors, to fight against the house of Israel, to bring the kingdom again to Rehoboam the son of Solomon. In this scripture is the history of the division of Israel into two nations. From here on is two seperate states. The ten tribes were rule by Jeroboam  while Judah, Benjamin and the Levites were under Solomon’s son REhoboam. It is this southern nation known as JEWS.  Please read their history. The North was removed by the Assyrians, the south went into slavery for 70 years in Babylon.

Most of you scholars link Bible prophesy speaking of the Jews to all Israel. There are separate prophesies for both nations. When Jacob is mention the prophesy is referring to all 12 tribes and not Jews only. Jeremiah prophesy of Jacob troubles do not apply to only the regathered Jews today.I will show you scripture where both Israel meaning the 10 tribes and Judah is mention. Isaiah 11v
12  And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.  13  The envy also of Ephraim shall depart, and the adversaries of Judah shall be cut off: Ephraim shall not envy Judah, and Judah shall not vex Ephraim. Have you ever read this scripture. Obviously not. Both Israel and Judah is mention in verse 12. Another name is mention in verse 13, Ephraim with Judah.  Who is Ephraim?? 2 Chron30v
And Hezekiah sent to all Israel and Judah, and wrote letters also to Ephraim and Manasseh, that they should come to the house of the LORD at Jerusalem, to keep the passover unto the LORD God of Israel.  2  For the king had taken counsel, and his princes, and all the congregation in Jerusalem, to keep the passover in the second month. How can anyone claim to have a knowledge of the scriptures and do not the history of the 12 tribes of Israel. The present regathering of Jews is not the regathering that will occur after the Messiah has return to earth with the saints. It has set the stage for other prophesies to be fulfilled. That include the rebuilding of the temple and institution of animal sacrifices. I want you to answer this question .For what purpose was the letter to the Laodicea  Church written.?? There is a conversation between Jesus and the church, notice the instructions in verse 18 I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see.  19  As many as I love, I rebuke and chasten: be zealous therefore ,and repent. These conditions are spiritual and need spiritual remedies.

Is this taking place in the church right now? How then can this church be saved? The first thing that Jesus tell it is to buy GOLD TRIED IN FIRE. wHERE IS THE “FIRE OF AFFLICTION, “that is to refine the church. God always speak to the majority. You yourself know full well that the majority is following , doctrines  of demons. God promise the Philadelphia church to save it. Rev 3v9
10  Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth. Here is a guaranteed from Jesus to save those of Philadelphia from something that is to come on the WHOLE EARTH. No such guarantee is given to Laodicea, instead it is called to repent. Why is Jesus calling a church to repentance when it is looking for the rapture. Jesus know the beginning and the end. Many questions that need biblical answers
