All family planning depends on the spirituality behind it.  Experience has shown that natural love and affection alone are not an adequate base for marriage. Day after day husband and wife must learn that they are incarnations of God . It is only through him, with him, in him that they can live and love. Thousands of men and women everywhere are indebted to Dr John Billings for his tremendous work on this new natural way of regulating births, originally called the Ovulation Method.

The purpose of Billings Method is to promote happy marriages in the following ways:

1.  Helping the childless to achieve pregnancy
2. Helping couples to live happily together while their baby is breast-feeding
3. Limiting the size of the family, as the parents think best.
4. The pre-selection of the sex of the baby, particularly in places where the absence of a baby boy causes marital unhappiness and even breakdown of marriages.
5. Helping husbands and wife to understand their combined fertility through a dialogue that brings them together with ever increasing peace, understanding, unity and love.
