Total misconception of the testimony of Apostle Paul in context from Romans chapter 9 to chapter 11. He expresses as like going through 'birth pangs', when he reflects about his 'kinsmen', the descendant of Jacob/Israel, Israelites. Ones, who are hostile and heart-harden to the saving power of the Gospel, and are not saved.
In Romans chapter 11, he starts of by witnessing to the Gentile church, 'has GOD rejected HIS people?' And. verse 2, he continues, 'GOD has not rejected HIS people whom HE foreknew.'
Verse 11, 'So I ask, did they stumble in order that they might fail? By no means! Rather, through their trespass salvation has come to the Gentiles, .......' Verse 16, 'If the dough offered as firstfruits is holy, so is the whole lump, and if the root is holy, so are the branches.'
Next verses, he uses the parables about a 'cultivated olive tree and branches', that is the true descendants of Jacob/Israel. And, 'cut wild olive tree branches', that are the Gentiles. To some of the branches of Israel have been cut off, and branches of the Gentiles have been grafted in.
But, down the line, he also warns Gentile believers, as grafted branches, that they can be cut off too due to unfruitfullness. And, GOD is able to graft back again the initial olive tree branches HE have cut before, back into their places. (Verse 17-24)
Verse 25-32, He concludes, also cautioning the Gentile believers to mindful of the reason and purpose of GOD, why the remaining Israel rejected the Gospel. The mystery he reveals, 'a partial hardening has come upon Israel, until the fullness of the Gentiles has come in. And in this way all Israel will be saved, .....'
'As regards the Gospel, they are enemies for your sake. But as regards election, they are beloved for the sake of their forefathers. For the gifts and calling of GOD are irrevocable.'
'For just as you were at one time disobedient to GOD but now have received mercy because of their disobedience, so they too have now been disobedient in order that by the mercy shown to you they also may now receive mercy. For GOD has consigned all to disobedience. that HE may have mercy on all.'
- all Israel will be saved - meaning, all the descendants of Jacob/Israel will be saved in the end.
Furthermore, points to ponder on - Why GOD have to send the two witnesses back to Israel when HE have rejected them, during the reign of anti-CHRIST?
And, during Armageddon, when the forces of the world joined together to completely destroy Israel for their good. Therefore, why Jesus have to descend with His angels from Heaven to defend Israel on that day? Even to the point to disintegrate the very enemy forces bodies from where they stand?
