HOT TIP: when it comes to biblical audience, it’s great to see what verses meant specifically for the Ephesians, Galatians, Corinthians, Hebrews, etc. There is a richness in seeing context wrapped around history, culture, and circumstance.
But. When it comes to salvation, there are only TWO biblical audiences - believer and unbeliever. Anything less, is a direct path to universalism and preterism.
The gospel was, and always will be, for both the Jew and The gentile with no distinction.
“the righteousness of God through faith in Jesus Christ for ALL who believe. For there is NO distinction: for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received BY faith.”
Romans 3:21-25
“For there is NO distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him.”
Romans 10:12
