I Cor. 15:35-58
After reaffirming the resurrection, Paul turned his attention to explaining how this resurrection would take place and what type of new body man would possess. He used an analogy from plant life. When a grain of wheat or any other seed is planted, it is resurrected as a new body, entirely different from that which was planted.
There are different kinds of bodies—plants, animals, birds, insects and humans. Various heavenly bodies also have differing characteristics.
Paul explained that man would have a new spiritual body. He did not describe its form or shape but that it will be different from the physical body that man now occupies. He did point out some of the differences between the two bodies.
The earthly body is sown as a corruptible, dishonorable and weakly natural body. It will be raised as an incorruptible, glorified and powerful spiritual body.
Paul described the contrasts between Christ and Adam. Adam, who came first, was a living being made of dust. All of mankind has lived in the image of Adam. Christ, who was second or last is a life-giving spirit from heaven. After the resurrection, all will live in the image of the heavenly Man. There will be no flesh and blood in heaven.
As he had explained to the Thessalonian Christians, Paul briefly described the resurrection. He said that not all will die before the end of time, but all will be changed from the corruptible fleshly body to the incorruptible spiritual body. Then death will be “swallowed up in victory.”
In view of the blessings of the resurrection, Paul instructed the Corinthians to “be steadfast, unmovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord.”
