Ringing The Church Bells Via SMS

We’re putting together a text-messaging reminder service for our meetings. Every Wednesday night at 7pm our website will send out a SMS message to the cell phones of everyone who signs up reminding them to get ready for Chi Alpha’s weekly worship meeting. It’s a simple message to help out those students who always mean to come but get busy doing something else and forget until the meeting is partway over:

Chi Alpha at 8:00 tonight in 300–300.

I’ve just tested the system and it works pretty smoothly. It’s the modern-day equivalent of ringing the church bells!

The script was really simple to write. If you use a unix-based system with PHP & PEAR installed you could easily adapt it for your ministry:

#!/usr/bin/php
 ?php
//sends SMS announcments to each person in Chi Alpha who wants them

require_once('Mail.php');
$parameters['sendmail_args']='';
$mailer=&Mail::factory('sendmail',$parameters);

$cells['Ferdinand Frosh']='5555555555';
$cells['Suzie Sophomore']='5555555555';
$cells['Jing Junior']='5555555555';
$cells['Sheila Senior']='5555555555';

$headers['From']='you@example.com';
$headers['Reply-To']='you@example.com';
$headers['Subject']='XA @ 8pm';
$body='Chi Alpha at 8:00 tonight in 300-300';

foreach ($cells as $cell) {
        if (empty($cell)) continue;
        $email=$cell.'@teleflip.com';
        //echo $email;
        $mailer->send($email,$headers,$body);
}
?>

All you have to do is customize the script (add cell phone numbers and the right “From” and “Reply-To” emails) and then add it to your crontab file with an entry like so:

0 19 * * 4 /path/to/announce.php

(Hint: type crontab ‑e to edit your crontab file).

By the way, it should go without saying that you never add someone to an SMS announcement system without their express permission! If you think email spam hacks people off, then just wait until someone has to pay a text-messaging fee for something they’re not interested in. The depths of their rage would astonish the Hulk.

Geekspeak: the reason I used the PEAR::Mail library was to make sure that the reply-to address was the one I wanted. I just couldn’t make it happen using the PHP mail() function alone. Everything was from “root@my webserver.” Very annoying.

Hymnody

I sent this email to our worship leaders and I thought others might be interested in it. 

Why do we try to incorporate a hymn each week into worship?

The shortest answer I can give is to quote C. S. Lewis on old books: “Every age has its own outlook. It is specially good at seeing certain truths and specially liable to make certain mistakes. We all, therefore, need the books that will correct the characteristic mistakes of our own period. And that means the old books. All contemporary writers share to some extent the contemporary outlook–even those, like myself, who seem most opposed to it. None of us can escape this blindness, but we shall certainly increase it, and weaken our guard against it, if we read only modern books. The only palliative is to keep the clean sea breeze of the centuries blowing through our minds, and this can be done only by reading old books. Not, of course, that there is any magic about the past. People were no cleverer then than they are now; they made as many mistakes as we. But not the same mistakes.” (from his introduction to Athanasius’ On The Incarnation).

The same thing is true of songs. There are some great worship songs out today and I want the majority of our worship to feature them. But I don’t want us to just feature them. They have notable weaknesses (pdf link) and so I want the “sea breeze of the centuries” to blow through our worship and keep us rooted.

Having said that, traditional hymn music doesn’t really connect with today’s students. That’s why I urge you to seek out or make up (yes, you are allowed to do that) contemporary arrangements for the hymns that we do sing.

I’ve found a few that illustrate what I’m talking about. Check out http://igracemusic.com/igracemusic/hymnbook/hymns.html

Each one has a sample mp3, lead sheets, tab sheets, and other resources available for worship teams.

Another excellent example is the Dave Crowder band’s recording of “All Creatures Of Our God And King.”

Anyway, I’ve been meaning to explain myself on that for a while but I’ve never actually gotten around to it. 

So there.

Encyclopedia Smackdown

In yet another vindication of Wikipedia, the prestigious science journal Nature just released a fascinating article, Internet encyclopaedias go head to head which did some thorough research and discovered that at least in science, Wikipedia is on par with the Encyclopedia Britannica for accuracy (if not elegance).

Personality Tests And Their Defects

The Cult of Personality Testing : How Personality Tests Are Leading Us to Miseducate Our Children, Mismanage Our Companies, and Misunderstand OurselvesSometime last year I read The Cult of Personality (since retitled to The Cult of Personality Testing). I picked it up on a whim at an offbeat bookstore in Half Moon Bay between two church services.

I loved it and found it utterly persuasive. I’ve had a long-simmering aversion to personality testing (rooted in a bad experience in seminary, observing friends get shafted by the Assemblies of God personality screening system for missionaries, some biting passages about psychology by Richard Feynmann, and being a critical thinker). Something about them always felt wrong (and I could even put parts of my unease into fairly persuasive words), but I never had the facts I needed to understand exactly where the problem lay. This book changed all that.

I mention it because I just read an article by Malcolm Gladwell called Personality Plus that covers the same ground. It’s a great intro to the concepts covered in the book.

So if you’re in the habit of referring to people by their Myers-Briggs type, or if you like to use the terms sanguine and choleric in casual conversation, or if you’ve ever made a decision based on the results of a personality test, READ THIS BOOK (or at least Gladwell’s article).

Is Stanford Worth It?

Our teammate Lindsey found a great article about the return-on-investment of elite schools like Stanford. 

Lion Rampant

My church went to see The Lion, The Witch and the Wardrobe this Saturday and we brought guests–3 to 4 times as many outside our church went to see it with us as did church members.

It was magnificent. From a fan’s perspective, it was as faithful to the book as you can expect a movie to be. From a technical perspective, it should say something that I found a beaver in chain mail utterly convincing. 

They even made Turkish Delight look appealing, which is truly nasty candy. If that was the most tempting snack available to Brits during the war I’m amazed they were able to hold out against the Luftwaffe. I mean, really. Turkish Delight? The stuff tastes like congealed fat.

I was destined to love the movie as long as it was even close to the book. I was more interested in the reactions of my neighbors: he an atheistic Jewish postdoctoral biology researcher at Stanford and she a not-really-practicing Hindu who works as a business consultant.

They loved it, too.

As we were talking about it afterwards, he commented “The reviews I’ve read are right–it’s definitely got Christian imagery but you have to look for it.”

While I think he downplayed the obviousness of the Christian message (it’s always winter without CHRISTmas–hello?), I think he was on to something. 

The movie did dilute some key dialog, but even if the dialog had been unaltered his point would still have merit. The story doesn’t so much tell the Christian message as it prepares one for it. It creates categories and understandings in your mind which serve as placeholders for the gospel. It’s like an extended parable that highlights a few truths:

  • This world is more fantastic than we dare believe.
  • Evil is seductive.
  • Evil need not prevail, either in our lives or in our world.
  • Evil must be fought.
  • We can’t win the fight against evil alone.
  • The one we need help from is our rightful King.
  • Our rightful King is not tame but he is good.

And given Phillp Pullman’s claim that the story was loveless I couldn’t help but marvel as the formerly fear-stricken Edmund—Edmund, who knew well the horrible extent of the Witch’s power—hurled himself at her to prevent the slaughter of Peter and incurred a life-threatening wound as a result. And I could talk of the love of the mother for her children, of the children for their father, of the children for each other, of the children for Aslan, of Aslan for his people, of the professor for his haplessly unloveable housekeeper, and of the children (especially Lucy) for Mr. Tumnus.

No love indeed. Pullman just has it in for Lewis.

Anyway, it’s an outstanding movie. I’ve been to precious few movies which caused the audience to burst into applause at the end. This was one.

That Never Occurred To Me

As I was doing some reading in the Dictionary of the Old Testament: Pentateuch, a thought jumped out at me in the article Family Relationships: stoning is a unique form of capital punishment because it requires the entire community to accept the responsibility for putting someone to death and it prevents any one person from having to serve as the executioner. It’s like a firing squad that way. I wonder how the debate on the death penalty woud change if we each had to help execute convicts…

College Factoid

“The average age of an undergraduate student is 26, reports the American Council on Education. But the average age of an undergraduate living on campus is 20, the group says.” (source: Alcohol makers on tricky path in marketing to college crowd)

Grownup School

Amazon has a feature called Grownup School that I was totally unaware of. It’s an awesome idea–ask experts what books they think are best in their field and let the rest of us in on the secret. Found via Freakonomics blog.

The Goblet of Fire

Paula and I went to see Harry Potter and the Goblet of Fire last night.

Loved it. Easily the best of the series so far. In fact, I think it was better than the book upon which it was based (and I NEVER think that about a movie).
