Of course they do. When both husband and wife belong to Christ through a mutual faith, they have all the ingredients needed to make a marriage rewarding and stable. At the heart of a Christian marriage is a special Christlike kind of love. The biblical word for this love is agape, the kind of love described by the apostle Paul in 1 Corinthians 13. Many marriages fail because the love the partners have for each other is not able to carry them through the rough times.
Agapic love is built especially for tough assignments.
It has a wonderful warmth and is exceptionally tender. But it is much more than that. It is the kind of love that continues to function even when one or both of the marriage partners do things that violate their trust in each other. Forgiveness plays a major role in agapic love. And this love keeps on doing loving acts even when the emotions are bent out of shape.
