The sermon centers on the biblical distinction between Paul's apostolic commission to the Gentiles and Peter's primary responsibility to the Jews, emphasizing that while each had a designated focus, neither role was exclusive. Drawing from Romans 11, Galatians 2, and numerous passages in Acts and Paul's epistles, it affirms that both apostles preached the same gospel—Christ's death, burial, and resurrection—for both Jews and Gentiles, with Paul consistently beginning his ministry in synagogues before turning to Gentiles when rejected. The message underscores that the Church is not a replacement for Israel or the Gentiles, but a new creation where all are united in Christ, regardless of ethnic or cultural background. The sermon warns against misinterpreting Scripture by creating artificial divisions, such as claiming separate gospels for Jews and Gentiles, and calls believers to faithfully proclaim the one gospel of salvation to all, while honoring God's distinct purposes for nations and individuals.
