Do you even realize you just made the argument for me? Probably not because most people get this chapter COMPLETELY WRONG. This chapter is not telling everyone that te=he Jews and Gentiles are ONE (even though we are the same unto Gid by Faith, just like a Male and Female are seen as the same unto Gid if we come unto Him by FAITH ALONO, but just like Males and Females Jews a Gentils are still Jews and Gentiles and God has clearly delineated times fir both, thus the TIME of the Gentiles = the Church Age, in-between the TWO TIMES of the Jews, the Spring Feasts and the Fall Feasts (so to speak).
So, if one understands what this chapter means, they understand you just defeated your own argument. Paul calls the Gentile Galatians FOOLISH because they were trying to be like the Jews by obeying the LAW (LOL....No kidding). Thus who has bewitched you that you began in the FAITH no have moved to the FLESH (serving the law as the Jews did before). Then he goes into a diatribe why the Law can not save you, why only faith can save you, why the Law is a CURSE and only FAITH in Jesus saves us, why the Law was NOT the original Promise, but was only added 430 years AFTER the Promise unto Abraham, thus only the PROMISE can save us, and the Law is thus done away with after the Promised SEED has come.
Then finally Paul makes a PO9NT that Satan has managed to TWIST, he tells them that the Jews and Gentiles are al the same, like male and females, but he isn'T saying there are no males and females nor that there is no Jews and Gentiles, he's telling them, HEY..........STOP TRYI G TO BE LIKE THE Jews and serving the Law, it avails NOTHING, its a CURSE, only FAITH can REdeem you so STOP tryi g to serve the Laws like the Jews, Gd sees al the Jews AND the Gentiles the exact same way, when they come unto him by FAITH ALONE !!
Every time I see someone say the Jews and Gentiles are now ONE I just laugh, makes and females are not ONE, anyone with common sense can read that and see that it is just the opposite of what they have been taught, in most cases.
