If you read the Revelation in it you will discover that it is the Jews, during the seventieth week of Daniel 9 prophecy, who are evangelizing the world, not the Church. 12,000 from twelve tribes of Israel are sealed by Gods Holy Spirit for this work. During the Church Age, there is no distinction between Jew and Gentile. During the Tribulation the Jews are specifically tasked with the message of salvation ONLY in the blood of Jesus.No, the Jews are but one tribe of Israel. The rest of the tribes are scattered in northwest Europe, the US and the UK countries.
WHEN you read the Revelation, you will see that God states He will seal 12,000 from the twelve tribes, where they are, in Israel or elsewhere. That one hour of study a day needs some tweaking, FRiend.
