A believer from the nations, when they convert to the teachings of Messiah Yeshua (the Torah) they are a convert to what? Christianity, which is a sect of Judaism. Thus all believers in Messiah Yeshua are converts to Judaism. Going through formal conversion is merely then an acknowledgment of an already existing reality for the benefit of the community to hold the individual accountable to the decision they have made. Some call it baptism. In Judaism it’s called conversion. Circumcision then for many, is merely an act of obedience to the command of G-d that all male offspring of Abraham are to be circumcised (and those bought from the nations in his house) – a reality that even Paul acknowledges is true of all believers: that they are the offspring of Abraham. To get circumcised then as a believer, when not done for purposes of securing a place in the World to Come, is done for the sake of (participating in and being held accountable by) the Jewish community (which is why Paul circumcised Timothy), and thus is an act of obedience to a command for someone who already is identified as one who claims Abraham as their father.

I must whole-heartedly disagree with that assertion. If there was one thing the Jerusalem Council actually decreed, it was that a Gentile did not have to be circumcised in order to be saved. By “circumcised,” it is meant that a Gentile did not have to become Jewish (Jews are circumcised, hence they are called “the circumcision” in the Brit Chad.). Gentiles in no way have to become Jewish in order to accept the whole of Torah in their lives. Please read Isaiah 56. A foreigner or stranger who accepts G-d’s mitzvot thus becomes a fellow-partaker of the covenant.
