1 Corinthians 15:20-23, 52-53

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] For since [it was] by a man that death came [into the world], it is also by a Man that the resurrection of the dead has come. For just as in Adam all die, so also in Christ all will be made alive. 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.

in a moment, in the twinkling of an eye, at [the sound of] the last trumpet call. For a trumpet will sound, and the dead [who believed in Christ] will be raised imperishable, and we will be [completely] changed [wondrously transformed]. For this perishable [part of us] must put on the imperishable [nature], and this mortal [part of us that is capable of dying] must put on immortality [which is freedom from death].
