Day 3 of Read: Revelation

Today we read chapters seven to nine. In the beginning of the reading we see those who are sealed by God, 144,000 total. I find it interesting that God makes it specifically clear that these are Jews (ethnic people from Israel) and that this is not some symbolic representation of Israel. The reason why we know this is because he takes the time to list out the specific tribes that they are from.
But what is equally as cool, especially for us non-Jews, is that in heaven every tribe, culture, language and nation will be represented. Out God is not a God of the Jews (or Americans) only, but of all people.
Finally, we see the final seal judgment given (which isn't actually described except that it says there was silence in heaven for about a half an hour) before the 7 trumpet judgments come. Here are the first 6 of the 7 trumpet judgments:

• 1) Hail and fire mixed with blood falls on the earth destroying a third of the earth's vegetation.
• 2) Something appearing like a flaming mountain is thrown into the sea turning a third of it to blood and bring much destruction and death to the oceans.
• 3) A great star falls from heaven which destroys a third of the earth's fresh water.
• 4) The sun and moon and stars are blocked out for one third of the time they used to shine.
• 5) A star falls to the earth and opens up a smoking abyss releasing locusts that torment the inhabitants of the earth that are not sealed by God for 5 months.
• 6) Four angels are released and they kill a third of mankind.

This does not sound like a good time to be alive, especially for those not "sealed by God". What do you think it means to have the seal of God?
