Husbands, love your wives, even as Christ also loved the church, and gave himself up for it; that he might sanctify it, having cleansed it by the washing of water with the word,

Outline:

It was a spectacular failure, but like so many things, it had such an ordinary cause.

Up not too far from Pittsburgh back in the 1800s there used to be a lake – Lake Connemaugh. The rich and wealthy of the day – everybody from Andrew Mellon to Andrew Carnegie – used to escape the hustle and bustle of Pittsburgh by going to their private club – the South Fork Hunting and Fishing Club. It was a nice enough lake – about 2 miles long and a mile across, 60 feet deep. At the far end of the River, there was an earthen dam that was more than 70 years old.

And then, on May 28th, 1889, it started raining. Within three days, the lake started overflowing that earthen dam, and within seconds, 20 million tons of water was barreling down the valley at 40 miles per hour. Along its way, it consumed rocks and trees and horses and debris … and then buildings and people and in less than a few minutes, over four square miles of the town of Johnstown, Pennsylvania. Over 2200 people were gone in the blink of an eye. The damage was so great that rescue crews couldn’t even get in for several days. As far as dam failures go, it was spectacular.

But even great failures – blowouts – usually have such ordinary causes. When the South Fork dam was constructed back in the 1830s by the Army Corps of Engineers, it was engineered very well. It was an earthen dam to be sure – but the engineers had taken precautions to ensure its integrity. As long as water was kept from overflowing the dam, it would hold.

Cast iron pipes had been fitted to ensure drainage – although in the course of time it would turn out that an unknowing owner had simply sold them away for scrap. A spillway had been carefully graded to the right of the dam where water would go rather than overtop the earth – but in the late 1880s, nobody was keeping it up. Indeed, when the studies were complete, final blame didn’t go to some terrorist or an evil man – it was just the fault of a grounds man who hadn’t kept up with the cleaning.

In my life, I like to avoid the massive failures – the blowouts. And to do that, I need regular cleaning. But let’s face it – I’m a guy. I don’t like words like “maintenance” and “care.” I want some immediate inoculation that keeps me good – a one-time shot of God to keep me through my whole life. But that’s not how blowouts work, and it’s not even how God works. If we would avoid the
