1 What then is the advantage of the Jew? or what the benefit of circumcision?
Romans 3:1 Cross References - Noyes
Romans 2:25-29
25 For circumcision is indeed a benefit to thee, if thou keep the Law; but if thou art a breaker of the Law, thy circumcision hath become uncircumcision.
26 If then he who is uncircumcised keep the precepts of the Law, shall not he though uncircumcised be regarded as circumcised?
27 Yea, those who are by nature uncircumcised, if they perform the law, will judge thee, who having a written Law and circumcision, art a breaker of the Law.
28 For he is not a Jew, who is one outwardly, nor is that circumcision, which is outward, in the flesh;
29 but he is a Jew who is one inwardly; and circumcision is of the heart, spiritual, not literal, whose praise is not of men, but of God.
1 Corinthians 15:32
32 If with the views of men I fought with wild beasts at Ephesus, what advantage is it to me? If the dead rise not, "let us eat and drink, for tomorrow we die."
Hebrews 13:9
9 Be not carried aside with various and strange teachings; for it is good that the heart be established with grace, not with meats, in which those who walked were not profited.
