A gap between the Jews and the Gentiles?
Most believers just accept that the Holy Spirit was poured out on all in Jerusalem, ten days after Jesus ascended into Heaven!
But when we read the book of Acts we will discover that this is not true and there is a substantial gap, letting us know that it was the believing Jews who first received and then much later the Gentiles through the work of the Apostle Peter.
This theme runs right through the New Testament in Revelation the tribulation will come to the Jews first, then to the rest of the world.
Acts 2:1-6, 10:44-46. 11:1.
