35 But someone will say, “How are the dead raised up? And with what body do they come?”
36 Foolish one, what you sow is not made alive unless it dies.
37 And what you sow, you do not sow that body that shall be, but mere grain — perhaps wheat or some other grain.
38 But God gives it a body as He pleases, and to each seed its own body.
The “someone” in v.35 is a doubter who questions the resurrection based on his own intellect. Paul calls him a fool (v.36) for doing this because he’s witnessed resurrection in his crops.
you (v.36) — stressed. He should know because he’s seen in in the plants he’s sowed.
unless it die (v.36) — The seed perishes to bring forth new life.
Most assuredly, I say to you, unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain (John 12:24).
The plant that comes from the seed is by God’s design (v.38)
The original kernel which is planted dies and rots away, but it results in a new crop of grains, all of them just like the one which was planted. Each seed planted will spring up with new seed which will resemble in every way that which was sown. To be sure there have been new elements added, and the old seed itself has perished and wasted away, but yet the new seed which comes forth out of the death of the old is similar in every respect to that which was planted. Our body, therefore, in the resurrection will resemble our present body (without the infirmities and blemishes and faults which it has here below). We will not all look alike in heaven, but we will be as different in appearance as we are here below. — DeHaan, pages 180-181.
