Unless Adonai builds the house, its builders labor in vain on it; unless Adonai watches over the city, the watchman keeps vigil in vain. (127:1)
We are God’s junior partners in the maintenance of the world. Everything we build relies on the existence of consistent and predictable natural law. In order for the bridge to bear the weight of a given amount of traffic, the engineer has to know that the materials will behave according to the laws of physics. In order for the medicine to treat the illness, the doctor relies on predictable chemical and biological interactions between the substance and the biological entity.
Bridges fail. Medication fails. A friend of mine computer-models fractures in materials. His models can only approximate how the real material behaves. This happens not because the laws of physics, chemistry, and biology are capricious, but rather because our knowledge of how those laws function in the real world is incomplete.
We could live for long stretches of time without being aware of the builder. For this reason, Judaism urges us to pause before we enjoy a product of the natural world and say a blessing. “You are the source of blessing, Adonai our God, eternal sovereign of the universe, who created the food we are about to eat.” That spark of gratitude reminds of that the house in which we live had a designer and a builder.
