Paul Peterson, a co-leader on the trip to Israel that I’ve been blogging about recently, talked about his father’s reaction upon returning from Israel several years ago. “I get it,” he told Paul. “Old stones. Lots of really old stones.”

What’s impressive, of course, isn’t the stones themselves but how they got to where they are. Thousands of years ago somebody stacked them atop one another to make walls, houses, temples, and the like. I’ve been reflecting on all those ruins. What lessons do they have for us?

I’ve seen “old stones” before this trip–at the acropolis in Athens, the forum in Rome, and the excavations in Ephesus, to name three places that come to mind. The Levant contains ruins that are much older than those sites, though. Jericho is one of the oldest cities in the world, first settled about 11,000 years ago. When we went there we didn’t visit the site of the ancient settlements, but we did see very old ruins in other locations. For example, at Tel Arad there are ruins of a Bronze Age Canaanite city that is about 5,000 years old. The site was abandoned for about 1,500 years before the Israelites settled nearby in the 11th century B.C.

This pattern of successive settlements at the same site made an impression on me. We saw numerous tels–hills consisting of layer upon layer of settlement, each abandoned, then built upon by the next occupants. At the first site we visited, Tel Gezer, we sat near the city gates in the 13th level; 12 more settlements had been built atop those ruins. This level is thought to have been the city built by Solomon mentioned in I Kings 9, so it dated to about the 10th century B.C. There are more levels beneath this one; no one knows how many.

Tels confound our simplistic historical schemes that divide all of human existence into just a few categories such as ancient, medieval, and modern. Even if we look at single tel, it’s quickly apparent that many different people groups once lived there and these residents were often separated from each other in time and probably in customs as much as we are separated from figures like Julius Caesar or Clovis. That way of looking at human existence challenges our tendency to privilege living in the present, in modern times. We moderns are just putting down one layer. With the passage of enough time, if anyone remembers the USA they will probably be hard-pressed to say how it differed from the Holy Roman Empire or the Hapsburg monarchy. That’s humbling.

For the most part, the ruins we saw were walled cities or fortresses. They were probably constructed out of stone because its sturdiness provided advantages when a neighboring king decided to invade. We learned something about what made for good fortifications. For example, the city gate was the most vulnerable point so a double wall was often built there, with a chamber between the walls to hold soldiers ready to fight anyone who breached the outer gate. Of course, even the most sturdy defenses could be surmounted. At Tel Lachish and again at Masada we saw massive siege ramps built by attacking armies (the Assyrians and Romans, respectively). At both sites the attackers were ultimately successful.

Ancient Canaanites and Jews lived in a world much different from ours, but we can understand their impulse to protect themselves. Though we no longer literally wall in our cities, modern nations use munitions, firewalls, and border fences to protect against threats. On an individual level, we lock our doors and turn on our security alarms; some of us have guns to defend ourselves. We accumulate savings to protect our retirement, buy insurance to protect against loss, and limit our openness with others to protect our emotions.

City walls were for the most part a good thing, as are our modern forms of protection. Once we have such fortifications, though, we are tempted to rely entirely on them. Jeremiah prophesied to the people of Judea:

“Cursed is the one who trusts in man,
who draws strength from mere flesh” (Jer. 17:5).

A couple verses later, he draws this contrast:

“But blessed is the one who trusts in the Lord,
whose confidence is in him” (v. 7).

Trust God. Do lock your door at night, though. None of the Old Testament prophets advised God’s people to dismantle the walls around their cities so that they would have to rely on God alone. There are a couple New Testament passages in which Jesus told his followers to dispense with ordinary precautions (e.g. Luke 10:4), but these instructions don’t seem to have been intended for everyone.

How do we insure that we depend primarily on God rather than turning to other sources of security? Jesus told stories about birds and flowers to help us with this (see Matthew 6:25ff). Birds and flowers don’t erect walls, but they’re doing fine. All the fortifications I saw on the trip are a good reminder that I, too, am prone to rely too much on my defenses. It’s important to remember that God is my source of security and only by trusting in him can I live in freedom, not in fear.
