I don't know where you are getting that from. The verse talks specifically about those walking in the light and does not mention resurrection. I suppose you could be taking about I Cor 15:51 but the we is Paul who is a believer and those he is writing to who are also believers.
I believe there are two possibilities. 1. Walking with God is the same as walking in the light. 2. People are re-incarnated giving them an opportunity to believe in Jesus.
Of course I believe the Rapture is an open invitation but Jesus said: Mat 22:11................
1 John 1:7 (B part) says the blood of Jesus.... cleanses us from all sin.
So, to me that means Jesus died for all, for everyone.
However, that does Not mean everyone will listen to Jesus.
That is why Jesus' ransom covers "MANY" and Not everyone as per Matthew 20:28.
After all, as Psalms 92:7 says the wicked will be ' destroyed forever '.
If we do Not want to ' perish ' ( be destroyed ) then we should ' repent ' as per 2 Peter 3:9.
I find there is a BIG difference between rapture and coming through the great tribulation of Revelation 7:14.
As Noah and family were Not air born, the saved great crowd of people of Revelation 7:9-10 will remain here.
I find Proverbs 2:21-22 lets us know who 'remains' here .
Who goes are the ones executed by the words from Jesus' mouth as per Isaiah 11:3-4; Revelation 19:14-16.
Kind of like if you had a beautiful occupied house that became infested with rats you would Not air lift the house or occupants but call the exterminator to exterminate the rats.
As far as the already dead, Acts of the Apostles 24:15 says (future tense) that there ' is going to be ' a resurrection.... In other words, Jesus did Not perform an re-incarnations but only resurrections.
So, Jesus was showing us a resurrection picture preview, or a coming attraction of what he will be doing on a grand-global scale during his coming 1,000-year governmental rule over Earth.
