"All women are not mothers, but all women are called to mother. To mother is to nurture, to train, to educate, to rear. As daughters of Eve, all women are uniquely gifted to help others in their lives become more of who they truly are--to encourage, nurture, and mother them toward their true selves. In doing this, women partner with Christ in the vital mission of bringing forth life."
-from Captivating, by John and Stasi Elderedge
I believe that it is implied (when read in context from the book) that by partnering with Christ in this way, mothering doesn't become smothering, and blesses those around us.
