Anyone who has experienced marriage will testify that it’s hard. That has been true across generations, cultures, and worldviews. Marriages never survive for decades on comfort and self-fulfillment, at least not happily. Marriages endure and thrive on unchanging, selfless mutual commitment to each other and to something bigger, stronger, and longer lasting than the marriage. Christian marriage, therefore, is an opportunity to show the world something—even better, to show them someone—strong enough to keep a marriage together and make it unbelievably meaningful and happy.
