The Scriptures plainly teach that some of Christ’s followers have been called to be joint heirs with him in heaven. (Romans 8:16, 17; 2 Timothy 4:18) Now, if Jesus was “made alive in the spirit,” is it not reasonable that his chosen followers destined for heavenly life would also be resurrected as spirits, with spirit bodies suitable for their new environment? (1 Peter 3:18) If that be true, then their fleshly corpses would not be resurrected.
This is exactly what the apostle Paul explained in discussing their resurrection, answering the question: “How are the dead to be raised up? Yes, with what sort of body are they coming?” (1 Corinthians 15:35) Obviously, if their selfsame fleshly bodies were going to be resurrected, there would be no point to that question. Paul explained, in reply, ‘God gives a body just as it pleases him.’ That principle applies to the resurrection of the dead also. Whereas a person lived and died with a “physical body,” what is raised is a “spiritual body.” So those resurrected to heavenly life will not have their fleshly bodies raised any more than did Jesus, who was resurrected “a lifegiving spirit.” In heaven they will have a spirit body, bearing “the image of the heavenly one.” (1 Corinthians 15:36-49) Paul clinches the point with his next statement: “Flesh and blood cannot inherit God’s kingdom, neither does corruption inherit incorruption.” -1 Corinthians 15:50.
So the Biblical evidence shows that the early Christians understood that their resurrection was not dependent on their body’s being preserved. Rather, it was the enemies of Christianity who erroneously believed that. Regarding second-century opposers who executed Christians, ancient historian Eusebius wrote: “The bodies of the martyrs…were at length burned and reduced to ashes by the wretches, and finally cast into the Rhone [River] …. These things they did as if they were able to overcome God, and destroy their resurrection.” These enemies said: “Now we shall see whether they will rise again.”
God’s actions in connection with Jesus and his joint heirs clearly show that Jehovah is not dependent on a preserved human body in order to resurrect a person. So, in regard to the future earthly resurrection in the New Order, Jehovah will be able to “give to each a body just as it pleases Him.”-1 Corinthians 15:38.
