For this reason [because I preach that you and believing Jews are joint heirs] I, Paul, am the prisoner of Christ Jesus on behalf of you Gentiles—

So I, the prisoner for the Lord, appeal to you to live a life worthy of the calling to which you have been called [that is, to live a life that exhibits godly character, moral courage, personal integrity, and mature behavior—a life that expresses gratitude to God for your salvation],

[it is this:] that the Gentiles are now joint heirs [with the Jews] and members of the same body, and joint partakers [sharing] in the [same divine] promise in Christ Jesus through [their faith in] the good news [of salvation].
