“Moreover, Isaac does not oppose his father but takes his advice with the utmost goodwill.

Therefore let all young people remember this example, and let them learn to respect the authority of their parents and the sanctity of the divine ordinance. Let them not think that intercourse is bestial, as the pope supposes it to be. But above all they should call upon their true Father and the Author of all things, in order that they may start without sin: “Lord God, Thou hast created me a man. Thou seest that I cannot be continent. I am calling upon Thee. Direct and bless my undertaking. Give me counsel and help. Choose for me a woman with whom I may be able to live honorably and to serve Thee, and by faith and prayer to overcome the inconveniences and difficulties of marriage.” Those who disdain these admonitions and are carried away by a blind impulse, without faith and prayer, will eventually experience, and be overwhelmed by, all kinds of misfortunes” (Luther’s Works, v.4 p.247).

“Therefore Abraham is concerned about his son and about the bride and the family of his son. And this is a matter of divine right and has to do with the definition of marriage over against the pope, who makes a brothel of marriage and does not see any difference between the coition of beasts and that of human beings.

I do not doubt that very many girls were offered to Isaac and that among them there were some who were beautiful, rich, and of noble birth. But Abraham closes his eyes and forbids his son to marry any one of them, not because he opposes the honorable desire of his son, who, because of his age, was now ready for marriage, but because he wants by all means to give him a respectable girl in marriage, not one who would be his son’s ruin and an offense to the entire church” (Luther’s Works, v.4 p.246-247).

“Therefore these dangers to his household came into his mind in order that he might not look for a beautiful or rich woman but might seek one who was honest and respectable, one who would be diligent and painstaking in managing the household. For to be subject to domineering wives is not only irksome but also disgraceful; and they should not lord it over their husbands but over oxen, sheep, and asses….

Abraham understood all these things, for he was a spiritual and intelligent man. Therefore he was unwilling to mix his seed with the blood of the Canaanites, lest his son become an idolater and the commingling of the seed lead at the same time to an intermingling of holy and idolatrous forms of worship. The worship of the saints is evidently plain and without show and splendor. On the other hand, the ungodly are puffed up with their righteousness, and by their show they very easily deceive the weak. Therefore Abraham saw that his son would nevertheless be in grave danger, even though he might not be led astray” (Luther’s Works, v.4 p.246).

“To sum the matter up: whoever finds himself unsuited to the celibate life should see to it right away that he has something to do and to work at; then let him strike out in God’s name and get married. A young man should marry at the age of twenty at the latest, a young woman at fifteen to eighteen; that’s when they are still in good health and best suited for marriage. Let God worry about how they and their children are to be fed. God makes children; he will surely also feed them. Should he fail to exalt you and them here on earth, then take satisfaction in the fact that he has granted you a Christian marriage, and know that he will exalt you there; and be thankful to him for his gifts and favors.

With all this extolling of married life, however, I have not meant to ascribe to nature a condition of sinlessness. On the contrary, I say that flesh and blood, corrupted through Adam, is conceived and born in sin, as Psalm 51[:5] says. Intercourse is never without sin; but God excuses it by his grace because the estate of marriage is his work, and he preserves in and through the sin all that good which he has implanted and blessed in marriage” (Luther’s Works, v. 45, p. 48).

“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).
