I don’t know if you pump your own gas these days or not. I suspect you do, like most of us these days, unless we visit New Jersey where it’s against the law to do so. This fact of modern life was satirized in a scene from one of my favorite movies, Back to the Future, in which Marty McFly is astonished to see four attendants at a filling station launch themselves at a car to check the air in the tires, clean the windshield, pop the hood to look at the oil and coolant levels, and take the driver’s order for gas. Now, those were the days!

Of course, if we’re paying cash, we have trudge over to the attendant—the horror of it all!—and schelp back to the car where we can then fill the tank ourselves. If we’re using a credit or debit card, our lives are somewhat easier. Indeed, if we used plastic to pay for gas, we rolled up to the pumps, got out, swiped our card through the reader, waited for the screen to respond, chose a grade of gas to our liking, and started pumping. Those days are gone, apparently, because the little magic screen now asks us to enter our zip code, a security measure in case we have stolen our own credit card and are trying to use it a half mile from where we live. I understand the need for this little addition, since having a credit number used and abused by someone else does not make for a good day in the life of the card holder, but I also have to confess it took me back a bit when I first had to enter the number with my little index finger. The screen also told me that if my postal code included letters, I had to see the attendant. Huh? I thought. There ain’t no letters in a zip code. What’s with that?

As it turns out, there are letters in postal codes of many countries around the world. Say you want to send a nice letter to Oxford Press in Oxford, England. You write your nice letter, put it in an envelope, and after putting on proper postage, address it to:

Oxford University Press

Great Clarendon Street

Oxford

OX2 6DP

Please note that the “postal code” includes letters and numbers, so they got it about 1/3 right. Not bad for a former mother country. They’re not alone, however, in using letters: about 250 other countries do as well, including, in some cases, the U.S. So, we’re in a minority by using only numbers. Who knew this? Not me!

Anyhow, all these numbers and letters got me to thinking about Christian belief and theology. We who have walked the path of belief most of our lives are familiar with the language and tenets of the faith. We know the hymns, stories, parables and theological terms. It’s all old business to us.

But to someone coming fresh to the story, it must all seem like a puzzle, a set of codes, a secret language which must be interpreted and studied to be understood. Such work is difficult and can, as we know, take years. And so, we need to be sensitive to those who are new to the faith and be willing and able to help them on their way, much as we were taught and guided and mentored by those who came before us and enlightened by the Holy Spirit. Through worship, Bible study, fellowship and service, we gained understanding of what we needed to know. We all have had in our lives parents, relatives, teachers and ministers who taught us the “mysteries of the faith,” so that these matters became, for us, ways of life. Jesus assured his followers, “My yoke is easy and my burden is light.” His teachings as compared to other rabbis were relatively uncomplicated since his word came from God.

I pray that we might be like our Savior in this as in other matters, showing others the way to the Master and to life everlasting. Amen.
