In 1988 Tanya Tucker had a country song titled “Strong Enough to Bend” that had a great message. In the song, she compared a willow tree to human relationships. She pointed out that willows can survive because their limbs can bend instead of breaking.
Interestingly enough, that concept is present in most living things in the creation. God rarely uses stiff materials in what He creates. On the other hand, humans tend to use rigid materials such as metals, ceramics, dry wood, etc. In your own body, how many stiff materials are there? Bones and teeth are about it. These are components designed for a specific purpose where hardness and stiffness are required. Most things in the biological world are soft, not brittle.
A classic example of the benefit of being soft and not hard is kelp and other marine algae. Those plants live in the violent world of surf. If you have ever surfed, you know the power of waves. I have seen surfboards thrown against rocks, pounded by the waves, and turned into a pile of shredded plastic in a matter of minutes. Kelp live in the surf with one end attached to rocks and the surface of the plant exposed to sunlight for photosynthesis. Kelp can survive because they are strong enough to bend.
Waves produce flows that reverse direction every few seconds. As soon as the plant grows longer than the distance the local water travels between reversals, the additional length of plant material is swept back and forth with the water. The plant literally goes with the flow. Since it moves the same direction as the water and at the same speed, there is no friction between the plant and the water. Kelp can grow to lengths well over 130 feet (40 m). A rigid plant like an oak tree in the surf would be pounded to splinters in a few hours.
Closer to home for most of us, are the leaves of land plants. Take a cardboard tube like a paper towel tube and try to bend and twist it. Then make a lengthwise slit in the tube and try it again. Notice how much easier it is after you cut the tube. The reason leaves have exotic shapes is to allow them to bend and twist rather than breaking in high winds or creating wind resistance that would take down the tree.
This design shows highly complex engineering, and our lives exist because of it. Imagine what would happen if our skin, eyes, ears, stomach, blood vessels, hair, etc. were not made of soft, pliable material. A good sneeze could shatter our face! Our Creator knew that being strong enough to bend was critical for our existence.
