How do we know that God uses Gentiles within the church?

Isaiah 61:5 states that Gentiles will stand and feed God's flocks, indicating their integral role in the church. This introduces the profound truth that all believers, whether Jew or Gentile, are called to serve and minister in God's Kingdom. In Ephesians 2:11-13, Paul further affirms that both Jews and Gentiles are reconciled in Christ, emphasizing that there is one body and one faith. This inclusion demonstrates that God's grace transcends ethnic boundaries and that all are equal within the church.
