remember that with the Jews circumcision was an everlasting covenant nothing to do with Salvation so that could not be removed, God does not break his covenants
If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
(Galatians 3:29)
Tell me, you who want to be under the law, are you not aware of what the law says? For it is written that Abraham had two sons, one by the slave woman and the other by the free woman. His son by the slave woman was born according to the flesh, but his son by the free woman was born as the result of a divine promise.
These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children. But the Jerusalem that is above is free, and she is our mother. For it is written:
“Be glad, barren woman,
you who never bore a child;
shout for joy and cry aloud,
you who were never in labor;
because more are the children of the desolate woman
than of her who has a husband.”
Now you, brothers and sisters, like Isaac, are children of promise. At that time the son born according to the flesh persecuted the son born by the power of the Spirit. It is the same now. But what does Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.” Therefore, brothers and sisters, we are not children of the slave woman, but of the free woman.
(Galatians 4:21-31)
does this seem to comport with you saying that the covenant with Abraham has nothing to do with salvation? (Galatians 4:21-31)
or is this in fact declaring that the covenant with Abraham is our salvation - being realized in Jesus Christ, the Seed ?
so what does it mean, then, that the promise, the covenant, our salvation by grace through faith, our partaking in Abraham -- what does it mean that this has nothing to do with the law, and what does it mean that now that faith has come, submitting to the physical sign of that covenant is tantamount to falling from grace and making Christ of no effect?
is physical circumcision a shadow? is it replaced with "the good things to come" ?
