We've had lots of discussions about prenups here over the years.
But I also think that some of the reasons behind prenups has somewhat changed, or at least there is a lot more to know about them than just what most people think.
I know most Christians think of prenups as an easy way to get out of a marriage, with visions of taking the money and running off with a younger or richer significant other on exotic vacations and living in a fancy McMansion.
But I'm at an age where pretty much everyone in my peer group is marrying into a blended family with an absolute myriad of things to consider.
For example, I've read about prenups in which, a widowed woman has an adult son who needs lifetime care, and part of the prenup includes a clause in which part of her funds are to remain set and used solely for her son's needs, no matter what happened.
I understand that it's God's perfect plan for marriages to stay together, but in a broken world, nothing is black and white. Saying, "Well if people just follow God's rules for marriage" is like saying we don't have any need for prisons or police because we can somehow just tell people to listen to God and everything will be alright. Even the best of Christians have fallen.
All I can work from is my own observations and I've seen Christian marriages break up for so many reasons people never anticipated when they first got married: affairs -- including online and even sites like the one we're all reading; one person getting sick (cancer, Alzheimer's, etc.) and the other person left because they were still healthy and didn't want to be a caretaker; a couple who got married, found out she was infertile after the marriage, and so the husband left for another woman because he wanted his own family; couples who have lost children due to miscarriage, accidents, or sickness, saw that loss every time they looked at their spouse, and wanted a "fresh start, without the reminders" -- with someone else.
I'm not saying any of these reasons are Biblical grounds for divorce -- I'm just saying, they happen.
And I think whether or not someone decides to get a prenup is really up to the couple, their pastor, potentially a lawyer, and God, very much depending on their own unique situation.
