How has the church been formed over the last 1900 years according to this teaching?
According to this teaching, the church has been formed over the last 1900-plus years by predominantly Gentiles who are being called out from whatever background, pagan or otherwise, and becoming members of the Body of Christ, as God visited the Gentiles to take out a people for His name.
Les teaches that in Acts 15, after Peter recounted how God at the first visited the Gentiles at the house of Cornelius, James, who was moderating the meeting, confirmed that God was taking out of the Gentiles a people for His name—the church, which is His body. For the last 1900-plus years, that church has been formed by predominantly Gentiles being called out from among whatever they were, pagans or whatever, and becoming members of the Body of Christ. As that began, the Jews became envious and opposed it everywhere Paul went, so God put a blindness upon the nation. Les reminds people that God deals with the Jew on two levels, national and personal; national blindness does not take away the personal opportunity for salvation.
