This is a reference to the Resurrection/Rapture, NOT the second coming of Christ.
The resur/rapt is the second coming. The second coming for salvation Heb 9:28, resurrection.
In the Resurrection/Rapture Christ comes FOR His saints.
In the second coming Christ comes WITH His saints.
They are both the same event.
The saints that Jesus brings with Him are the OT saints.
When He comes for us, they will be with Jesus already.
Between these two events we have the Marriage of the Lamb. So it cannot possibly be all one event. In fact, that would be absurd.
The marriage supper of the Lamb can only take place after the kingdom is delivered up to the Father.
1 Cor 15:23-28 says that the kingdom is delivered up to the Father, After death is destroyed Rev 20:14-15.
So the marriage cannot take place until after death is destroyed.
