We have been complementary beyond anything I could have imagined. Her capacity to nurture others grew in me as we became one. My capacity to plan, direct, and lead in our family grew in her as we became united in marriage. I realize now that we grew together into one—slowly lifting and shaping each other, year by year. As we absorbed strength from each other, it did not diminish our personal gifts.

Our differences combined as if they were designed to create a better whole. Rather than dividing us, our differences bound us together. Above all, our unique abilities allowed us to become partners with God in creating human life. The happiness that came from our becoming one built faith in our children and grandchildren that marriage could be a continuing source of satisfaction for them and their families.

You have seen enough unhappiness in marriages and families to ask why some marriages produce happiness while others create unhappiness. Many factors make a difference, but one stands out to me.

Where there is selfishness, natural differences of men and women often divide. Where there is unselfishness, differences become complementary and provide opportunities to help and build each other. Spouses and family members can lift each other and ascend together if they care more about the interests of the other than their own interests.
