The only way to deal with your errors is to deal with them ONE at a time. Look at Romans 11:25-28:
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
27 For this is my covenant unto them, when I shall take away their sins.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers’ sakes.
Your ignorance is the very ignorace Paul addresses in verse 25 in these words, "For I would not, brethren, that ye should be IGNORANT of this mystery."
Ask yourself what is the "mystery" that Paul does not want the "brethren" to be ignorant about? He states it clearly - "that blindness in part is happened to Israel."
Ask yourself now, what "Israel" is Paul talking about that "IS" in blindness as He writes these brethren? Whatever "Israel" that 'IS" in partial blindness remains in blindness to a specified time and that time is spelled out in THREE different ways beginning in verse 25 and concluding in verse 27.
1. "UNTIL the fullness of the gentiles be come in" - v. 25
2. "There SHALL come out of Zion the Deliverer" who future tense "SHALL turn away the ungodliness from Jacob" - v. 26
3. "WHEN I SHALL take away their sins" - v. 27
Now, has the fullness of the Gentiles come in as to our present day? No!
Now, has the deliverer come out of Zion who "SHALL" turn their sins away since Paul wrote to our present day? No!
Now, "when...shall" he take away the sins of "Jacob" or "Israel"? Not until the two events occur in #1 and #2 which was still FUTURE from when Paul wrote this epistle as he uses the future tense "shall." It is still future from our present day.
Therefore, the Israel in verse 26 that was in partial blindnes when Paul wrote "is" still in blindess today "shall" continue in blindness "until" AFTER the fullness of the Gentiles be "come in." That is, all the elect Gentiles must first "come in" to God's kingdom BEFORE God takes away the sins of this "Israel".
Therefore, this "Israel" does not include but excludes all GENTILE ELECT. Indeed verse 28 declares they are PRESENTLY "enemies of the gospel" for the sake of the Gentiles in order that all the Gentiles elect shall "come in."
Can't get it any clearer than this! This Israel does not contain ONE SINGLE SOLITARY GENTILE and this "Israel" does not presently have their sins remitted and will not have their sins remitted "until the fulness of the gentiles be COME IN." This has not happened. The delieverer Paul spoke of had not happened at the time Paul wrote this as he uses the future tense "shall come." The deliver has not yet come and therefore is still future from our day and it is "WHEN" that deliverer comes that the sins of this "Israel" SHALL be remitted. Hence, this "Israel" is STILL IN THEIR SINS - STILL IN THEIR BLINDNESS and will continue to be until all the elect Gentiles come in and until the Deliverer comes from Sion. Hence, this Israel is not the "remnant" nor is it the Gentile elect - can't get it any more simpler than that.
Now before you respond according to your normal babble and according to your normal repeating your same absolute nonsense - read carefully what I have said and TRY to disprove it contextually IF YOU CAN!! You can't and so you won't try but you will do what you always do with contrary evidence - IGNORE IT!
