Needless to say, such incentives won't be forthcoming. That's because incentives would indicate that the proponents of covenant marriages want those who undertake such marriages to be happy and to stay married. That is not what the covenant proponents or sponsors want at all, of course. As in most of their political initiatives, their underlying interest here is in seeing sinners suffer. Sex has to be punished in this view.
All sex does.
And perhaps the most gruesome punishment for such sinning , for people who don't have much else in common, and who discover after some of the heat has dissipated that they don't really like one another very much, and probably never did, is knowing they'll have to go on sharing company until death really do them part. Not even Poe was that gruesome. The people who oppose divorce because they want to see sex punished are generally the same people who oppose abortion for the same reason. Abortion in their kook view is just a way for people who've had sex, probably illicit sex, to get off the hook-to escape the consequences of their sinful behavior. To avoid suffering for their sin.
