Those in Christ have the assurance now of not coming into the judgment of the second death. This assurance does not require a physical resurrection. We have already have passed from death to life...,
Jn 5
24 “I assure you and most solemnly say to you, the person who hears My word [the one who heeds My message], and believes and trusts in Him who sent Me, has (possesses now) eternal life [that is, eternal life actually begins—the believer is transformed], and does not come into judgment and condemnation, but has passed [over] from death into life.
25 I assure you and most solemnly say to you, a time is coming and is [here] now, when the dead will hear the voice of the Son of God, and those who hear it will live.
That is clearly a Spiritual resurrection. Born into a new life.
Jn 5 cont'
26 For just as the Father has life in Himself [and is self-existent], even so He has given to the Son to have life in Himself [and be self-existent]. 27 And He has given Him authority to execute judgment, because He is a Son of Man [sinless humanity, qualifying Him to sit in judgment over mankind]. 28 Do not be surprised at this; for a time is coming when all those who are in the tombs will hear His voice, 29 and they will come out—those who did good things [will come out] to a resurrection of [new] life, but those who did evil things [will come out] to a resurrection of judgment [that is, to be sentenced].
When Jesus comes again, we are raised bodily to receive our Glorious reward. This is the day of eternal reckoning for all the living and the dead, as 2thess 1 points out.
