I’ve learned a great deal in my three years as an RCIA team member about NFP. My favorite piece was a man who said that his wife was created perfect and that he didn’t need to control her fertility but that they together needed to balance their relationship. Very powerful stuff.
At bottom, it’s giving up control and trusting in God. That trust spills over into all areas of life. I found it to be very liberating. It saddens me whenever people say things like, “we’re going to stop at two.”
