The message in Ephesians 3:6 is a revolutionary one for its time, as it declares that Gentiles, who were once considered outsiders, are now fully included in God's plan of salvation through the gospel. This inclusion means that Gentiles are not second-class citizens in the Kingdom of God but are equal heirs with Israel. They are part of the same spiritual family, sharing in the promises given through Christ Jesus. This was a radical departure from the traditional Jewish understanding of God's covenant, which was seen as exclusive to Israel.
Paul's message here is about the breaking down of walls that once separated people. It speaks to the heart of the Christian message of reconciliation and unity. In Christ, there is no division based on race, culture, or heritage. All believers are united in one body, the Church, and share in the same promises of hope, salvation, and eternal life. This passage encourages believers to embrace diversity and unity, reflecting God's inclusive love and grace.
