Jeannette and David had tried unsuccessfully for some years to become pregnant. She said, “Have you thought about it that after God created mankind as male and female he blessed them. Then he told them to be fruitful. Do we ever ask God to bless our love-making so that it can be fruitful?” “That is a great idea, even though it feels a bit strange,” David replied.
Genesis 1: 20 – 2-4a. So God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them and said, “Be fruitful and multiply and fill the earth and subdue it and have dominion over the fish of the sea and the birds of the air and over every living thing that moves upon the earth.”
Pope Francis: Conjugal love does not end with the couple. The couple in giving themselves to one another give not just themselves but also the reality of children, who are a living reflection of their love. AL 165
