What will our spiritual bodies be like?

Answer:

John stated, "Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is" (I John 3:2). Thus, we must accept the fact that we have not been given details about our spiritual bodies beyond the fact that they will be spiritual like God.

The most detail is given by Paul.

"But someone will say, "How are the dead raised up? And with what body do they come?" Foolish one, what you sow is not made alive unless it dies. And what you sow, you do not sow that body that shall be, but mere grain--perhaps wheat or some other grain. But God gives it a body as He pleases, and to each seed its own body. All flesh is not the same flesh, but there is one kind of flesh of men, another flesh of animals, another of fish, and another of birds. There are also celestial bodies and terrestrial bodies; but the glory of the celestial is one, and the glory of the terrestrial is another. There is one glory of the sun, another glory of the moon, and another glory of the stars; for one star differs from another star in glory. So also is the resurrection of the dead. The body is sown in corruption, it is raised in incorruption. It is sown in dishonor, 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. There is a natural body, and there is a spiritual body. And so it is written, "The first man Adam became a living being." The last Adam became a life-giving spirit. However, the spiritual is not first, but the natural, and afterward the spiritual. The first man was of the earth, made of dust; the second Man is the Lord from heaven. As was the man of dust, so also are those who are made of dust; and as is the heavenly Man, so also are those who are heavenly. And as we have borne the image of the man of dust, we shall also bear the image of the heavenly Man. Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption. Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed-- in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible has put on incorruption, and this mortal has put on immortality, then shall be brought to pass the saying that is written: "Death is swallowed up in victory" (1 Corinthians 15:35-54).

If you think for a moment, you would realize that a mortal body would be unsuitable for immortal existence. The body I have is of the world. Like the world, it is falling apart. It cannot last through eternity. The idea of birth, growth, and death, the idea of childhood and adulthood, the idea of male and female, all originate from our physical existence. When we are raised we will have spiritual bodies. The physical concepts do not apply. "For in the resurrection they neither marry nor are given in marriage, but are like angels of God in heaven" (Matthew 22:30).
