There is no one Biblical method as to how one should obtain a wife. Why, Scripture discusses some sixteen or so different possible ways:
1) Find an attractive prisoner of war, bring her home, shave her head, trim her nails, and give her new clothes. Then she’s yours. (Deut. 21:11-13)
2) “Lay hold on” a virgin who is not betrothed to another man, and “know” her, but afterwards pay her father a sum of money. Then she’s yours. (Deut. 22:28-29)
3) Find a prostitute and marry her. (Hosea 1:1-3)
4) Find a man with seven daughters, and impress him by watering his flock.–Moses (Ex. 2:16-21)
5) Purchase a piece of property, and get a woman as part of the deal.–Boaz (Ruth 4:5-10)
6) Go to a party and hide. When the women come out to dance, grab one and carry her off to be your wife.–Benjaminites (Judges 21:19-25)
7) Have God create a wife for you while you sleep. Note: this will cost you a rib.–Adam (Gen. 2:19-24)
8) Agree to work seven years in exchange for a woman’s hand in marriage. Get tricked into marrying the wrong woman. Then work another seven years for the woman you wanted to marry in the first place. That’s right. Fourteen years of toil for a wife.–Jacob (Gen. 29:15-30)
9) Cut 200 foreskins off of your future father-in-law’s enemies and get his daughter for a wife.–David (1 Sam. 18:27)
10) Even if no one is out there, just wander around a bit and you’ll definitely find someone.–Cain (Gen. 4:16-17)
11) Become the emperor of a huge nation and hold a beauty contest.–Xerxes or Ahasuerus (Esther 2:3-4)
12) When you see someone you like, go home and tell your parents, “I have seen a woman; now get her for me.” If your parents question your decision, simply say, “Get her for me. She’s the one for me.”–Samson (Judges 14:1-3)
13) Kill any husband and take HIS wife. (Prepare to lose four sons though.)–David (2 Sam. 11)
14) Wait for your brother to die. Take his widow. (It’s not just a good idea, it’s the law!)–Onan and Boaz (Deut. or Lev., example in Ruth)
15) Don’t be so picky. Make up for quality with quantity.–Solomon (1 Kings 11:1-3)
16) A wife?–Paul (1st Corinthians, chapter 7)
Humourous, but the point should be clear: Scripture doesn’t mandate any one particular method.
That’s up to you. As you perceive yourself Spirit-directed, while exercising wisdom and discernment, of course.
Therefore don’t let anyone say either, on the one hand, that one particular method, whether dating, courtship, betrothal, arranged marriages, etc., is ‘the Biblically preferred / sanctioned’ method, or, on the other hand, that Scripture resolutely condemns a particular method (if it even mentions said method; Scripture is likely not exhaustive of all possibilities, and doubtless wasn’t intended to be, either) – unless, of course, you can find a specific Biblical passage against it. If you do, please share with everyone; we’re all ears. But you won’t.
AND Paul reminds us that it is legitimate to choose not to marry, either, for that matter.
