This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.

So what is the mystery we have been talking about? Paul explains it in verse 6. The mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.

In the Old Testament, God had made unconditional promises to Abraham and his seed. And, as we learn in other places in Paul’s writings, Christ is that seed, and those who trust Christ are heirs together of the promise. (Romans 4:16; Galatians 3:7-9; Galatians 3:29) That is what Paul is alluding to here in verse 6.
