The point of your argument, as I see it, is for those martyrs to receive 'glorified bodies', and immortality when Jesus Returns.
That is what the bible says though.
Rom 2:5 But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and
revelation of the righteous judgment of God;
Rom 2:6
Who will render to every man according to his deeds:
Rom 2:7 To them who by patient continuance in well doing seek for glory and honour
and immortality, eternal life:
Just as many scriptures show, immortality comes at the second coming (the last trump) and when the living are also changed into immortals.
1Co 15:52 In a moment, in the twinkling of an eye,
at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1Co 15:53 For this corruptible must put on incorruption, and
this mortal must put on immortality.
1Th 4:16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and
the dead in Christ shall rise first:
1Th 4:17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
1Co 15:42 So also is the resurrection of the dead. It is sown in corruption; it is raised in
incorruption:
The word "incorruption" here is the same exact word "immortality" in 1Co 15:53 which proves when the saved dead resurrect, they are immortal.
The dead rise at the second coming and that is also when immortality takes place.
Php 3:20 For our conversation is in heaven; from whence also
we look for the Saviour, the Lord Jesus Christ:
This is a second coming reference.
Php 3:21
Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
And as all the previous scriptures affirm, the bodies of the righteous will be changed to be like His body and that is when immortality is received.
