“Let such heathen go their way; we will not argue with them. If they should be lucky enough to obtain such wives the marriages would still be un-Christian and without faith. They trust in God as long as they know that they do not need him, and that they are well supplied. He who would enter into wedlock as a Christian must not be ashamed of being poor and despised, and doing insignificant work. He should take satisfaction in this: first, that his status and occupation are pleasing to God; second, that God will most certainly provide for him if only he does his job to the best of his ability, and that, if he cannot be a squire or a prince, he is a manservant or a maidservant.
God has promised in Matthew 6[:25, 33], “Do not be anxious about what you shall eat, drink, and put on; seek first the kingdom of God and his righteousness, and all these things shall be yours as well.” Again Psalm 37[:25] says, “I have been young and now am old, yet I have not seen the righteous forsaken, or his children begging bread.” H a man does not believe this, is it any wonder that he suffers hunger, thirst, and cold, and begs for bread? Look at Jacob, the holy patriarch, who in Syria had nothing and simply tended sheep; he received such possessions that he supported four wives with a large number of servants and children, and yet he had enough. Abraham, Isaac, and Lot also became rich, as did many other holy men in the Old Testament.
Indeed, God has shown sufficiently in the first chapter of Genesis how he provides for us. He first created and prepared all things in heaven and on earth, together with the beasts and all growing things, before he created man. Thereby he demonstrated how he has laid up for us at all times a sufficient store of food and clothing, even before we ask him for it. All we need to do is to work and avoid idleness; then we shall certainly be fed and clothed. But a pitiful unbelief refuses to admit this. The unbeliever sees, comprehends, and feels all the same that even if he worries himself to death over it, he can neither produce nor maintain a single grain of wheat in the field. He knows too that even though all his storehouses were full to overflowing, he could not make use of a single morsel or thread unless God sustains him in life and health and preserves to him his possessions. Yet this has no effect upon him” (Luther’s Works, v. 45, p.47-48).
