“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?
That is what it means to find a wife. Many have wives, but few find wives. Why? They are blind; they fail to see that their life and conduct with their wives is the work of God and pleasing in his sight. Could they but find that, then no wife would be so hateful, so ill-tempered, so ill-mannered, so poor, so sick that they would fail to find in her their heart’s delight and would always be reproaching God for his work, creation, and will. And because they see that it is the good pleasure of their beloved Lord, they would be able to have peace in grief, joy in the midst of bitterness, happiness in the midst of tribulations, as the martyrs have in suffering. (Luther’s Works, vol. 45, p.38-39).
