You have to take in account what life is like today as well. If we're talking 100 years ago, Other cultures and times got married when they were young to start families young. They had multiple children to help the family work. They had their parents and grandparents live with them even when they were married. 20 and 30 years ago they were still getting married young but that's when divorce has gone up.
If you look at different eras, you can see the steady trend of the "marriage" and "family" being desensitised and for many reasons. That's why I dont agree with the 20's marriage approach anymore. Such is not the case today. I agree that marrying early would cut down on sexual immorality, but i also think the tradeoff is that we'd have more divorce than ever. In a culture where its' "all about me" im not sure that most teens or young adults are capable of having serious relationships where they can support themselves (remember the cost of living, at least in America, is much much higher). We dont live in that world anymore where marriage is a serious commitment.
As for being financially stable- ha you BETTER be! The number one reason for divorce is because of money issues. If you dont marry financially stable it's like being off to a bad start. You can't pay your bills and you go without electricity, a place to live, food, etc. True love overcomes but honestly no one wants to be a pauper. The alternative is being married and living under your parents which could be a good or a really really horrible thing. Its important to be able to support yourself most definately.
I'm not sure if having kids to help the family work was a reason back then... would be interested to look into, I thought kids would be more of a burden, even though they did start working a lot earlier.
I agree with you on the part there - the world doesn't take marriage as a serious commitement, and it's a sad thing, I look at my grandparents, great aunties, uncles etc, they are all together, yet you look around the world today, many divorced people in their 40's-50's and if you look at younger people. They may not be divorced, but that's only because they chose not to get married before starting a family.
However, I don't think that these things need to apply to christians, I think if we sort of just go 'urgh no marrying early wont work' because we see that there is so much divorce I think we're just buying into the world. Sort of like it's view on marriage - till death do us part - or till it gets too hard. Rather than the biblical view on marriage which is till death do us part, for richer or poorer, sickness and health. - Christians I think need to ignore what the world thinks of marriage and take it for what it''s meant to be.
As for the part about teens or young adults supporting ourselves, again I think we're buying into the world view, (costs may be dif between aus and america, but I'd imagine they would be fairly similar, think min wage is higher here) realistically what do we need to survive? Food, shelter, clothing, that's all, lets say $200 for rent (highly dependent on where you live), $50 a week for food, $50 a week for other random expenses, would it be easy? well, not really, but that shouldn't be the point, when you marry it's for richer or poorer. $300 a week isn't hard to earn, any full time job will get you this. (in aus anyway)
I disagree with that point that the number one reason for divorce is money issues, it's the number one thing that gets blamed for divorce. As you said, true love overcomes
& if you are both relient on god then the marriage will not fall apart. Living with your parents would be weird after marriage, but then if it's needed.
I also think the sexual immorality issue is a major issue with young christians (more so than it is focussed upon), I wonder how many fall away, struggling with issues of loneliness, lust etc where if we were getting married younger they wouldn't. corinthians something has that line about getting married to prevent sexual immorality, why today is it more... 'be mature and deal with your lust, then look for marriage' rather than the biblical approach. I'm not saying that a marriage based on lust is a good idea but you can see where I'm coming from here. - edit - I'm not saying here that these things don't need to be dealt with and we should do that simply by marrying, they need to be dealt with anyway! but why we don't even see marriage as a solution to this when the bible tells us it is... dunno
I'm not saying that these things aren't good things to have if your planning on getting married, it's smart to be financially stable & everything you mentioned.
Which people often are more in their 30's, but is it centrally important to marriage? Not really, if someone your marrying isn't willing to be a pauper with you & you with them then you don't have enough commitement! God will always provide for our needs, what is that verse about god providing... something about king solomon birds and flowers.
You might have some more experience than me in this sort of area (you are a couple of years older) but this is my take on it anyway.
