marriage is honorable:
Let marriage be held in honor among all, and let the marriage bed be undefiled; for God will judge the immoral and adulterous.
(Heb 13:4)
for companionship:
Then the LORD God said, "It is not good that the man should be alone; I will make him a helper fit for him." ..... Then the man said, "This at last is bone of my bones and flesh of my flesh; she shall be called Woman, because she was taken out of Man." Therefore a man leaves his father and his mother and cleaves to his wife, and they become one flesh.
(Gen 2:18, 23-24)
for having children:
God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them, and God said to them, "Be fruitful and multiply, and fill the earth"
(Gen 1:27-28)
lifelong bond:
Jesus answered, "Have you not read that he who made them from the beginning made them male and female, and said, 'For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh'? So they are no longer two but one flesh. What therefore God has joined together, let not man put asunder."
(Matt 19:4-6)
A wife is bound to her husband as long as he lives. If the husband dies, she is free to be married to whom she wishes, only in the Lord.
(1 Cor 7:39)
So I would have younger widows marry, bear children, rule their households, and give the enemy no occasion to revile us.
(1 Tim 5:14)
wives are to be subject to their husbands:
Wives, be subject to your husbands, as to the Lord. For the husband is the head of the wife as Christ is the head of the church .... As the church is subject to Christ, so let wives also be subject to their husbands in everything.
(Eph 5:22-24)
Wives, be subject to your husbands, as is fitting in the Lord. Husbands, love your wives, and do not be harsh with them.
(Col 3:18-19)
husbands are to love their wives:
Husbands, love your wives, as Christ loved the church and gave himself up for her.
(Eph 5:25)
Husbands should love their wives as their own bodies. He who loves his wife loves himself. For no man ever hates his own flesh, but nourishes and cherishes it, as Christ does the church.
(Eph 5:28-29)
Let each one of you love his wife as himself, and let the wife see that she respects her husband.
(Eph 5:33)
sexual intercourse fulfills a duty to one's partner:
The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For the wife does not rule over her own body, but the husband does; likewise the husband does not rule over his own body, but the wife does. Do not refuse one another except perhaps by agreement for a season, that you may devote yourselves to prayer; but then come together again, lest Satan tempt you through lack of self-control.
(1 Cor 7:3-5)
an unmarried person is free to please the Lord, but the married seek to please their partner:
The unmarried man is concerned about the things of the Lord, how to please the Lord; but the married man is concerned about worldly things, how to please his wife, and his interests are divided. And the unmarried woman or girl is concerned about the things of the Lord, how to be holy in body and spirit; but the married woman is concerned about worldly things, how to please her husband.
(1 Cor 7:32-34)
marriage reduces the temptation to immorality:
Because of the temptation to immorality, each man should have his own wife and each woman her own husband.
(1 Cor 7:2)
marriage is better than burning with inordinate desire:
To the unmarried and the widows I say that it is well for them to remain single as I do. But if they cannot exercise self-control, they should marry. For it is better to marry than to be aflame with passion.
(1 Cor 7:8-9)
celibacy is good - for some:
It is well for a man not to touch a woman.
(1 Cor 7:1)
There are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven.
(Matt 19:12)
many of the early church leaders were married:
Do we not have the right to be accompanied by a wife, as the other apostles and the brothers of the Lord and Cephas?
(1 Cor 9:5)
Now a bishop must be above reproach, the husband of one wife, temperate, sensible, dignified, hospitable, an apt teacher ....
(1 Tim 3:2)
Let deacons be the husband of one wife, and let them manage their children and their households well.
(1 Tim 3:12)
Christ will marry the Church:
Let us rejoice and exult and give him the glory, for the marriage of the Lamb has come, and his Bride has made herself ready.
(Rev 19:7)
I betrothed you to Christ to present you as a pure bride to her one husband.
(2 Cor 11:2)
no need for marriage in eternity:
In the resurrection they neither marry nor are given in marriage, but are like angels in heaven.
(Matt 22:30)
