"Where do wars and fights among you come from?" Enmities and quarrels are concepts with the same meaning. They differ perhaps in that the first designates the more general condition of the communities.
The latter designates more particular manifestations of this general disorder. In general, they signify the unpeaceful condition of the communities, whose features the apostle has partly set forth above.
"Do they not come from your pleasures," and so forth. In the form of a question, this is the answer to the question posed.
By pleasures are meant the same thing that the apostle above called desire, or desires: an inclination toward delight in what is sensual and sinful, namely sinful desires.
The apostle calls them desires that war in the members, that is, in the bodily members. The members are presented as the seat of these desires.
This is not, of course, in the sense that the members are the beginning or source of these desires. Rather, they are the organ of their manifestation.
In the members, or through the bodily members, these desires wage war. Against what? Against themselves and against the desires of others that do not correspond to them or hinder their satisfaction.
This is both the inner disorderly struggle of different desires within one man, and their struggle with the desires of others when they collide, as the following discourse shows. The first serves as the foundation for the second.
