Sam recently wrote (speaking of Acts 24:15):
“Yet, he uses the phrase, “about to be” (mellein esesthai) which, as a phrase, is used in two other places in Acts where the context shows that the subject matter clearly took place within the time of the original audience (11.28; 27.10).”...From Wright’s massive study on the subject, Resurrection of the Son of God, it is shown that “age to come” was the age of resurrection for the Rabbis. The souls of the righteous were in sheol…this was an “intermediate” state of the saints...Short answer: Paul was writing proleptically as he looked forward to the age about to come. the powers of the age to come (transforming, regenerating, resurrecting powers) were already at work in Paul’s day, and the powers of the age to come would characterize the age to come. The OT saints would be raised from sheol, and to be absent from the body is to be present with the Lord.
Sam says Acts 24:15 was partly about Hades being emptied (because Sam acknowledges "mello" in the text).
15having hope toward God, which they themselves also wait for, [that] there is about to be a rising again of the dead, both of righteous and unrighteous;
Sam says that Revelation 20 is still happening today. What was Revelation 20 about? Emptying Sheol/Hades. No bodies anywhere in the text. So either this is a past event (Rev 20), or Sam has to have Hades being re-filled again and again with both righteous and unrighteous souls. Sam, is anyone experiencing the "second death" yet - without resurrected bodies? Or are believers still going to Hades, since you say Acts 24 was partly about Hades, because of the time text? Both the righteous and unrighteous are rasied in Acts 24.
13and the sea did give up those dead in it, and the death and the hades did give up the dead in them, and they were judged, each one according to their works; 14and the death and the hades were cast to the lake of the fire — this [is] the second death; 15 Anyone whose name was not found written in the book of life was thrown into the lake of fire.
