When does the rapture of the church happen?
The rapture of the church occurs when the fullness of the Gentiles has been brought in—when the body of Christ is finally filled and the last person is saved. At that point the church is removed, and God resumes His dealing with Israel.
Les explains that Israel's spiritual blindness is temporary—'until' the fullness of the Gentiles is brought in (s518-s527). The fullness of the Gentiles is the body of Christ (s528-s529). When the body of Christ is finally filled, the last person is saved, and the church is removed—the rapture—then God will pick up where He left off with Israel (s530-s535). Israel's blindness will come to an end, and they will again have a spiritual relationship with Jehovah God (s535-s538).
