Elizabeth and Mark have the unique perspective of incorporating Natural Family Planning (NFP) into their married life for over twenty-five years. This presentation is not a “how-to” course. Rather, it begins with a brief theology of NFP and how it differs from contraception. It looks at the big lies of contraception and how generations of women (and men) have been misled. Most importantly, it looks at the amazing advantages of NFP: 100% safety, 99% effectiveness, and longer and happier marriages! This presentation can be given to adults, teens, or both.
