From the post:
Sex within marriage is not for ministry. Sex within marriage is for the husband and wife of that marriage.
This is well said.
I did have a question, though, about whether sex is also for children, as in, the producing of them. And if so, I wonder if it affects the shape of the argument? Being fruitful and multiplying, after all, has as its aim the establishing of God's rule in his creation—Genesis 1:28. And once we introduce the idea that sex might not be solely for the husband and wife, but have some external purpose in view as well, we are back into the question of whether or not you might have sex (within marriage of course—that's assumed) for reasons other than that you simply enjoy it.
Another verse that comes to mind is Malachi 2:15
Did he not make them one, with a portion of the Spirit in their union? And what was the one God seeking? Godly offspring. So guard yourselves in your spirit, and let none of you be faithless to the wife of your youth.
I don't really know what this verse means. But the bit that I understand again seems to point to a view of sex that says it is about more than mutual enjoyment, as terrific as that is.
Now what Jen eviscerates, stays eviscerated so read what she said and feel the weight of it; feeling the weight will paradoxically result in a great burden of guilt being lifted from some, particularly wives of ministers. But there is more to be said; something Jen herself would likely acknowledge.
