For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God. Rom 2:28-29
Indeed so, but some of the children of the 'natural branches' are grafted back in very quickly toward the return of Jesus , since they know the scriptures far better than most, just are more careful about listening to sinners than most... being a Jew outwardly does NOT in any way prevent coming to be one inwardly and all descendants of Jacob do so eventually:-
Romans 11:26 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:
equally we know from Jesus that all the firstfruit saints are descendants of named sons of Jacob [Rev 7:3-8], so some at least are indeed Jews inwardly as well as outwardly , the rest are from the idol-worshipping House of Israel to whom alone Jesus said he was sent... so the OT and NT are not incompatible as sinners teach in churches, salvation of the gentiles later [Rev 7:9-10]is indeed of the Jews and one should pray for the remnant saints of Israel because one's later salvation depends upon their ceasing from sin now which you likely cannot do because of bands to Satan... read all the scripture before deciding what to believe from sinners , then you will see only saints and prophets know to teach ... we have their written record for sake of reproof , so read it all ,Satan has been twisting bits of it for Millennia, but can't twist it if you read it all and get understanding from seeking it in prayer to God and meditating on what you don't yet see...
Romans 10:1 Brethren, my hearts desire and prayer to God for Israel is, that they might be saved.
For they are not Israel who are of Israel, nor are they all children because they are the seed of Abraham; but, In Isaac your seed shall be called. Rom 9:6-7
As Jesus says only the few of Israel are taken as firstfruits -Rev 7:3-8, sealed in spirit baptism... so not all Israel wrestles with God as Israel did to get his name [yisra el ... it means one who struggles with the Mighty One]
so indeed not all fulfil the name Israel who are descended of him ,but nevertheless there are none who are not descended from his sons named by Jesus in Rev 7:3-8 as firstfruit saints ... try to read more carefully what scripture says , that some of Israel do not follow Jesus does NOT mean that all who do now do so are not of Israel, Jesus states explicitly that they are, so why don't you want to believe him in Rev 7:3-8... ?
For we are the circumcision, who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh Pp 3:3
This is simply a repetition of what is said in the OT , that following God's law is of the spirit of love and truth of the law, but the flesh leads man astray with its lusts... ironially most who call themselves 'Christians' continue to sin because of lusts of the flesh , find it impossible to stop sinning as Jesus commands and is required of everyone who names Christ , so Jesus says he will indeed leave anyone behind who ha not departed from sin by the time he returns, and we know FEW will do so [Matt 7:14] , so why pretend MANY 'Christians'can follow Jesus now listening to sinmers, when both Jesus and the saints say that FEW will find the way now, and the many who are destroyed [Matt 7:13] are saved LATER [Rev 7:9-10]
It just makes no sense to listen to sinners whenone could just read and believe in Jesus' words and those of his saints and the prophets of God...
