Strike one: Israel rejected God the Father when they ALLOWED the death of John the Baptist. Who preached the Kingdom and who recognized and preached Jesus as the Messiah when after His baptism by John, God announced “THIS IS MY SON. IN WHOM I AM WELL PLEASED.” Rejecting that message was rejecting God the Father.
Strike two: Israel rejected Christ and His earthly ministry. They DEMANDED His death. They rejected God the Son. That was Strike two.
Strike three: Israel rejected God the Holy Spirit at Pentecost. They were offered the Kingdom and promised Christ’s return if they would repent and be baptized, at which point they would receive the Holy Spirit.
They would not and their wrath against the believers grew worse and worse, until they actually KILLED Stephen THEMSELVES. Strike three. The Book of Acts is the fall of Israel because of their unbelief. And the beginning of the time of the Gentiles. Which is what Romans through Philemon are all about: what God was doing once He blinded Israel and set them aside because is their unbelief.
Their blindness will be taken away when the times of the Gentiles is complete, the Body of Christ is complete and is raptured. At which time God once again turns His eyes back to Israel and all prophecies are fulfilled: the tribulation and Second Coming and the Millennial Kingdom established.
One more thing: The three strikes and you’re out: 1. The Father. 2. The Son. 3. The Holy Spirit.
When they rejected the Holy Spirit there remained no other way to be saved. This is why Jesus said that all manner of sin would be forgiven except speaking against the Holy Spirit, which would not be forgiven in this world nor the world to come. Because there was no remedy left. Strike three you’re out.
