The Rapture occurs first.
Then Jesus will open the seals. That's the wrath of the Lamb, the 7-year tribulation. Then the 2nd Coming.
Please, repent & believe the Gospel.
1 Corinthians 15:3-4 ~ For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures.
