I have this quote on both blogs right now. This is not to be annoying, but there is a different readership for each. Calvin understood that God provides certain things through the light of nature and when a person goes against that providence it is sin.
Here he speaks of the use of the breast for the nurturing of children and how when a woman goes against that light of nature it is sinful. (Unless it is for medical purposes; which are rare circumstances.)
". . .the Lord does not in vain prepare nutriment for children in their mothers' bosoms, before they are born. But those on whom he confers the honor of mothers, he, in this way, constitutes nurses; and they who deem it a hardship to nourish their own offspring, break, as far as they are able, the sacred bond of nature. If disease, or anything of that kind, is the hindrance, they have a just excuse; but for mothers voluntarily, and for their own pleasure, to avoid the trouble of nursing, and thus to make themselves only half-mothers, is a shameful corruption."
Commentary on Genesis 21.7
-What are some other "lights of nature" that we need to be mindful of?
-Why is our culture "uncomfortable" with the way in which God has provided for infants to be nourished?
-What role does Christian modesty play in providing nourishment for a woman's children?
