How will we know when the tribulation starts?

We will not physically hear trumpets in the sky and see bowls being poured out. We will see death, sickness, famines, and wars, and political changes and we will need discernment. The Bible says that the return of Jesus comes like a thief upon those who are not watching. We are commanded not to be idle like that and we are given the task of evangelizing until the end. People in those days feel comfortable enough to live as usual, getting married and having families until the end.

How do we know which covenant is the seven-year one? How do we know when to take somerhing political seriously?🧐
