Oh yes, soon, we (every Christian) shall all be changed, in a moment, in the twinkling of an eye, at the last trumpet. Though there is no mention of Christ’s coming anywhere in the following passage, the mention of the trumpet sounding, of the resurrections, and of the statement that “we shall be changed,” tells us clearly that this passage is speaking of what Paul wrote to the Thessalonians, in 1 Thessalonians 4:14-17. Hence, the teaching here is the same—about the end of the church age, signified by the “last trumpet,” when the dead in Christ are resurrected (and changed, glorified), followed by the living, who are instantly changed (glorified) without dying, and taken up (raptured).
1 Corinthians 15:50-55
Now I say this, brethren, that flesh and blood cannot inherit the kingdom of God; nor does the perishable inherit the imperishable. 51 Behold, I tell you a mystery; we shall not all sleep, but we shall all be changed, 52 in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we shall be changed. 53 For this perishable must put on the imperishable, and this mortal must put on immortality. 54 But when this perishable will have put on the imperishable, and this mortal will have put on immortality, then will come about the saying that is written, “Death is swallowed up in victory. 55 “O death, where is your victory? O death, where is your sting?” NASB
Notice that in this passage, the emphasis is not on the snatching up of believers in rapture, but on the “change” that will happen to the living without having to die. What a marvelous moment that will be! And what a defeat that will be for death; for it will be cheated of its last earthly victims. Oh what joy! God will “swallow up death for all time,” and He “will wipe tears away from all faces” (Isa. 25:8).
