Now if we preach that Christ rose from the dead, why do some of you say that there is no resurrection of the dead? If there is no such thing as a resurrection of the dead, then Christ did not rise; and if Christ did not rise then our preaching is of no value and your faith also is of no value.
But some one will say, "How do the dead rise and what kind of body will they have when they come back?" foolish one! The seed you sow does not come to life again unless it dies. What you sow is not the body that will be, but a mere grain, perhaps of wheat or of some other seed. God gives it the kind of body that he sees fit, to each kind of seed a body of its own.
All flesh is not the same; there is human flesh, another flesh of beasts, another flesh of birds, and another of fishes. There are heavenly bodies and also earthly bodies, but the splendor of the heavenly is one thing and that of the earthly is another. There is one splendor of the sun, another splendor of the moon, and another splendor of the stars; for one star differs from another in splendor.
So it is with a man's body when he rises from the dead. It is sown a perishable thing, it is raised imperishable; it is sown without honor, it is raised in glory; it is sown in weakness, it is raised in power; it is sown a natural body, it is raised a spiritual body. If there is a natural body, there is also a spiritual body.
In a moment, in the twinkling of an eye, we shall be changed and this perishable body must put on the imperishable and this mortal body put on immortality. Then shall come true what is written in scripture "Death is swallowed up by victory. O grave, where is your victory? O death, where is your sting?" Thanks be to God who gives us the victory through our Lord Jesus Christ.
