Man never made any material as resilient as the human spirit. (Bernard Williams, late English philosopher)

During the difficult years of World War II, scientists were developing all kinds of materials that could be produced cheaply and be more resilient than those currently in use. Synthetic rubber, Dacron, nylon—all kinds of things were created that continue in use today. But yet, as Williams wrote, the human spirit is the most resilient of God’s unique creation.

For you know that when your faith is tested, your endurance has a chance to grow. (James 1:3)
