1 Corinthians 15:39-41
39-41You will notice that the variety of bodies is stunning. Just as there are different kinds of seeds, there are different kinds of bodies—humans, animals, birds, fish—each unprecedented in its form. You get a hint at the diversity of resurrection glory by looking at the diversity of bodies not only on earth but in the skies—sun, moon, stars—all these varieties of beauty and brightness. And we're only looking at pre-resurrection "seeds"—who can imagine what the resurrection "plants" will be like!
42-44This image of planting a dead seed and raising a live plant is a mere sketch at best, but perhaps it will help in approaching the mystery of the resurrection body—but only if you keep in mind that when we're raised, we're raised for good, alive forever! The corpse that's planted is no beauty, but when it's raised, it's glorious. Put in the ground weak, it comes up powerful. The seed sown is natural; the seed grown is supernatural—same seed, same body, but what a difference from when it goes down in physical mortality to when it is raised up in spiritual immortality!
