34. (19) Conjugial love depends upon the wife's love, and such too is the husband's love reciprocally; the wife's love does not depend on her husband's love. The reason is that just as the will acts on the understanding, good acts on truth; that is why it is said that a man ought to cleave to his wife. The reverse is true of those who are not in conjugial love.

We tend to think of "fruit" in two ways in natural language. One is as food that grows on trees and vines, sweet and delicious, and able to be eaten without harming the plant in any way. Another is as the things we produce, what our work yields for the betterment of the world. These are obviously connected: we are like trees, producing things that "feed" the world in some way, just as the tree produces fruit that feeds us. It makes sense, then, that the idea of fruit in the Bible is bound closely to the idea of goodness. Fruits that are eaten represent the desire for good and the energy to do what is good; fruit that is produced is the actual good that we go into the world and do.
