When were the Jews supposed to bring the knowledge of salvation to the Gentiles in the Old Testament plan?
In the Old Testament plan, the Jews were to bring the knowledge of salvation to the Gentiles after Israel had received the King and the Kingdom. Only then could they carry out those promises to the Gentile nations. That order changed when Israel rejected the King and Kingdom, and Jesus was crucified.
Les explains that according to the Old Testament program, after Israel had the King and the Kingdom, they could carry out all these promises of taking the knowledge of salvation to the Gentile. This flies in the face of the understanding that no unbelievers would go into the Kingdom. That changed when Israel rejected the King and the Kingdom, Jesus was crucified, went back to heaven, and would not immediately come after the Tribulation but would wait 2,000 years while Israel is set aside and the Church Age runs. The Old Testament gave no indication of that interval; it was part of the secret God had not revealed.
