Good Tuesday morning. Yesterday was National Lazy Day. I think I nailed it!
I don’t know why Paul wrote so much about circumcision, but here goes:
25 Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision has become uncircumcision. 26 So, if those who are uncircumcised keep the requirements of the law, will not their uncircumcision be regarded as circumcision? 27 Then those who are physically uncircumcised but keep the law will condemn you that have the written code and circumcision but break the law. 28 For a person is not a Jew who is one outwardly, nor is true circumcision something external and physical. 29 Rather, a person is a Jew who is one inwardly, and real circumcision is a matter of the heart—it is spiritual and not literal. Such a person receives praise not from others but from God.
All that to say, that ALL are subject to the law. Paul answers the next logical objection, coming from a Jewish mindset: What about circumcision? Being circumcised, in obedience to God’s command to Abraham and his descendants (Genesis 17:9–10), ensured that Israelites would be identified as God’s people, the Jews. Apparently, many Jewish people believed that those who were circumcised were, by definition, saved. They would not be judged by God even if they broke His law. The ritual, for them, was enough to establish their salvation.
Paul disputes that idea, but he does not discard circumcision itself. He acknowledges that circumcision matters for the Israelites; it is an act of obedience in and of itself. However, the whole point of circumcision is lost if a Jewish person under the law breaks God’s law. Literally, Paul writes that their circumcision becomes “foreskin.” In other words, such a person is no better off than if they had not been circumcised, at all.
These words would have come as a shock to religious Jews who believed they were saved through circumcision and belonging to God’s chosen people. They should challenge the attitude of anyone who thinks that religious rituals, ceremonies, or other sacraments can overcome the stain of sin.
(I got some help from bible ref.com as I was as confused as you!)
