Read 1 Cor 15:20-28,it shows five events. The first resurrection (Jesus,the first fruits),the second resurrection (those who are saved at His coming),death is destroyed,Jesus delivers the (completed) kingdom to the Father, Jesus submits to the Father.
If you look in Rev 20 you see the same sequence of events,2 resurrections,then death is destroyed,then heaven. The thing that aligns these events is death being destroyed, it happens only once.
In 1 Cor 15 :52-54 it says that death is destroyed after the last (7th) trumpet.In Rev ch 11 it shows the second
resurrection in the story of the two witnesses and the 7th trumpet judgement scene.
