Are believers in far-off places like Bolivia part of the same body of Christ as believers in America?
Yes. The context states that believers in the jungles of Bolivia are in the same body as believers in Oklahoma and the rest of America. All are members of that same spiritual organism, the Body of Christ, regardless of location or station in life.
Les explains that the Body of Christ is a Pauline term used exclusively by Paul, distinct from the Gospel of the Kingdom. He points to verse 5, where believers of the Gospel of Grace, being many, are one body in Christ, and every one members one of another. Les then shares that missionaries in his home told of believers in the jungles of Bolivia, yet they are in the same body as believers in Oklahoma and the rest of America. All are members of that same spiritual organism, from wherever they are and whatever station in life. He calls this crucial to understand.
