>>19411113In the bible God made a covenant with Abraham and the people of the nation of Israel aka the sons of Jacob and circumcisions. It was to show who pledged to uphold the covenant of god.
It was an action done willingly but from then on it was done on children on the 8th day without their choice so it doesnt offer any salvation henceforth.
“A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.” – Romans 2:28-29
Says Paul, and it is known that religious tradition isnt going to being you into heaven and it requires a "circumcision of the heart" aka allowing God into your heart to cut away your sinful behaviours and allow yourself to transform and soften your heart to the glory of God.
