Why did God send Paul primarily to the Gentiles?
God sent Paul primarily to the Gentiles because Israel had rejected and crucified their Messiah. In the early chapters of Acts, Peter could not get them to believe, so God raised up Saul of Tarsus, known as Paul, and directed his ministry primarily to Gentiles. Individual Jews could still be saved during the age of grace.
Les explains from Jeremiah 31 that God is not through with Israel; the covenant promises to Abraham, Isaac, and Jacob still stand, and Israel will not cease as a nation while the ordinances of sun, moon, and stars remain. But when Israel rejected and crucified their Messiah, and Peter could not get them to believe in the early chapters of Acts, God raised up Saul of Tarsus, Paul, and sent him primarily to the Gentiles. Earlier, God had gone primarily to the Jew. Gentile exceptions existed then, and individual Jews can still be saved in the age of grace. Les also warns that the church must not be mixed with Israel in the tribulation, because that period is primarily God dealing with the nation of Israel.
