The 7 yr tribulation is For the Jewish people. God is giving them a second chance because they Are His chosen people. There will be the 144,000 Jews being sent out to evangelize and multitudes Will repent / come to Christ as their Messiah. Revelation 7 vs 14 and back up to vs 9.
We will probably have to disagree on this. I'm not saying there wont be a pre-trib rapture. But even if there is... people will be saved during the tribulation. It won't only be Jews.
Rev 7:9; After these things I looked, and behold, a great multitude which no one could count,
from every nation and all tribes and peoples and tongues, standing before the throne and before the Lamb, clothed in white robes, and palm branches were in their hands;
Rev 7:10; and they cry out with a loud voice, saying, "Salvation to our God who sits on the throne, and to the Lamb."
Rev 7:11; And all the angels were standing around the throne and around the elders and the four living creatures; and they fell on their faces before the throne and worshiped God,
Rev 7:12; saying, "Amen, blessing and glory and wisdom and thanksgiving and honor and power and might, be to our God forever and ever. Amen."
Rev 7:13; Then one of the elders answered, saying to me, "These who are clothed in the white robes, who are they, and where have they come from?"
Rev 7:14; I said to him, "My lord, you know." And he said to me, "
These are the ones who come out of the great tribulation, and
they have washed their robes and made them white in the blood of the Lamb.
The people who receive the white robes will be from every race, every tongue, every nation of the world. It's not just the Jews who are given a second chance.
