In every marriage that ends in disaster, some stupid decisions were made with respect to God’s regulations. If God’s regulations were followed scrupulously, not only would there be no divorces; there would be no unhappy marriages. To violate the regulations of God is not only an exercise in disobedience but also an exercise in foolishness. If you want a happy marriage, the most intelligent thing you can do is to submit to God’s regulations. They are designed to promote and protect your full happiness.
