1 Corinthians 15:40
There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another. There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.
The verse belongs to the teaching on the resurrection, which is a resurrection of the body. The whole person sleeps in the grave until the resurrection, and this is what gives the resurrection of the body its importance. The verse distinguishes kinds of bodies and their differing glory, and in this way supports the distinction between the mortal body and the immortal body.
Bodily identity does not depend on retaining the same particles of matter but on organization, so resurrection does not require the mortal body's matter to become the immortal body. The growth of a planted seed in the surrounding passage teaches the resurrection of the body and the renewing of the heart. The human agent plants the seed and God waters it and causes His sun to shine on it until the small shoot springs up. From this development of earthly things spiritual things are to be learned.
