The world says of marriage, “Brief is the joy, lasting the bitterness.†Let them say what they please; what God wills and creates is bound to be a laughingstock to them. The kind of joy and pleasure they have outside of wedlock they will be most acutely aware of, I suspect, in their consciences. To recognize the estate of marriage is something quite different from merely being married. He who is married but does not recognize the estate of marriage cannot continue in wedlock without bitterness, drudgery, and anguish; he will inevitably complain and blaspheme like the pagans and blind, irrational men. But he who recognizes the estate of marriage will find therein delight, love, and joy without end; as Solomon says, “He who finds a wife finds a good thing,†etc. [Prov. 18:22].
Now the ones who recognize the estate of marriage are those who firmly believe that God himself instituted it, brought husband and wife together, and ordained that they should beget children and care for them. For this they have God’s word, Genesis 1[:28], and they can be certain that he does not lie. They can therefore also be certain that the estate of marriage and everything that goes with it in the way of conduct, works, and suffering is pleasing to God. Now tell me, how can the heart have greater good, joy, and delight than in God, when one is certain that his estate, conduct, and work is pleasing to God? – Martin Luther ((Luther, M. (1999).
