God gives a seed its body (in other words, its plant) as he has chosen.
The past tense of the verb to choose
points us back to creation, when God ordained that every kind of seed would bring forth plants of its own kind (Genesis 1:11–12). From beginning to end, God is in control of seeds, plants, and human bodies.
38 puis Dieu lui donne un corps comme il lui plaît, et à chaque semence il donne un corps qui lui est propre.
