When does the outcalling of the Gentiles into the body of Christ end?
The outcalling of the Gentiles into the body of Christ, which is the Church, ends with the Rapture. The fullness of the Gentiles also ends at the Rapture, not at the Second Coming. The Rapture occurs just before the Tribulation, seven years before the Second Coming.
Les teaches that the Rapture will take place just before the Tribulation and seven years before the Second Coming. He contrasts two processes: the times of the Gentiles, during which Jerusalem is under Gentile control, will end at the Second Coming; but the fullness of the Gentiles, meaning the outcalling of the Gentiles into the body of Christ, the Church, will end with the Rapture. Therefore, the outcalling into the body of Christ concludes at the Rapture.
