1 Corinthians 15:20, 23

But now [as things really are] Christ has in fact been raised from the dead, [and He became] the first fruits [that is, the first to be resurrected with an incorruptible, immortal body, foreshadowing the resurrection] of those who have fallen asleep [in death]. [Col 1:18]

But each in his own order: Christ the first fruits, then those who are Christ’s [own will be resurrected with incorruptible, immortal bodies] at His coming.
