We will have the same bodies
There are many Scriptural reasons for believing that we will be raised with the same body that died. First, Christ was raised in the same body He had before He died. We know this because the tomb was empty (
Luke 24:1-6) and because His resurrected body retained scars from the crucifixion (
John 20:25,
27). Since Christ's resurrection is the pattern that our resurrection will follow (
Philippians 3:20-21;
1 Cor. 15:49), then we will also be raised with the same body.
Second, this is also evident from the very meaning of the term "
resurrection of the dead" (
1 Corinthians 15:13, etc.). The phrase means: that which is dead (namely, our body) is made alive. If the same body that died is not the body that was raised, Paul could not call it the "resurrection of the dead." It would not be a resurrection at all.
Third, the phrase "the dead will be
raised" (
1 Cor. 15:52) also communicates this. John Piper comments on this verse that, "If God meant to start all over with no continuity between the body I have now and the one I will have, why would Paul say 'the dead will be raised'? Why would he not say, 'the dead will not be raised (since they are decomposed and their molecules are scattered into plants and animals for a thousand miles) and so God will start from scratch'? He did not say that, because it is not true" (
Future Grace, 372).
Fourth,
Philippians 3:20-1 says that our earthly body is
transformed into conformity with Christ's body in the resurrection, not that God creates a new body from scratch: "For our citizenship is in heaven, from which also we eagerly wait for a Savior, the Lord Jesus Christ; who will
transform the body of our humble state into conformity with the body of His glory, by the exertion of the power that He has even to subject all things to Himself."
Fifth, Jesus speaks of the resurrection as involving the coming forth out of tombs, which strongly indicates that the resurrection is the reanimation of the body that had been lied to rest originally: "An hour is coming, in which all who are in the tombs will hear His voice, and will come forth; those who did the good deeds to a resurrection of life, those who committed the evil deeds to a resurrection of judgment" (
John 5:28-29).
Sixth, Paul's statement "it is sown a perishable body, it is raised an imperishable body" (
1 Corinthians 15:42) establishes that there is a continuity between our current body and our resurrected body, for it is the same "it" in both cases.
Seventh, verse 53 indicates that the same body we have now (which is mortal), will become immortal: "For this perishable must put on the imperishable, and this mortal must put on immortality."
