While the Liberty Bell may be one of the most well-known symbols Philadelphia, Pennsylvania, the keystone hanging over it may have more historical significance. That precise stone, placed at arch’s apex, holds the entire structure together. It was so important in many of the buildings of the city that the state of Pennsylvania became known as the Keystone State. The state held the union together, much in the same way the stones hold buildings together. In the Christian faith, Jesus is that keystone—the one who holds the church, our lives, and even the universe together. In Revelation 3:7-13, Jesus made it clear that real faithfulness isn’t sinless perfection; it’s holding fast to him as our keystone, keeping his word and never denying his name.
