Paul answers that Jews have significant benefits, including being entrusted with God's revelations. He intends to fully list these advantages later when discussing whether God remains faithful to Israel through Christ. Romans 3:1-8 briefly addresses this question before Paul thoroughly covers it in Romans 9-11, where he finishes listing the privileges of Jews such as adoption, covenants, and the promises made to their ancestors.

1. The Study of Roman 3:1-4:20
By Jean Smith
Paul answers in verse 2 that there are great benefits to being a Jew.
"Great in every respect." Then he begins a list of advantages (verse 2b),
but he only mentions one thing: "First of all, that they were entrusted
with the oracles of God." Paul stops here because he intends to finish
this list later (in 9:4-5). In fact, this whole problem of whether God is
being faithful to his covenant with Israel in the work of Christ is taken
up in Romans 9-11, so that Romans 3:1-8 is just a brief detour to deflect
the criticism until he gets to Romans 9. There he finishes the list like
this: ". . . who are Israelites, to whom belongs the adoption as sons, and
the glory and the covenants and the giving of the Law and the temple
service and the promises, whose are the fathers, and from whom is the
Christ according to the flesh, who is over all, God blessed forever. Amen
