We were in high school. Mary was completely normal in every way but one. Mary was blind. She often asked me to describe what things looked like: clouds, flowers, and the sunset. I could never do it in less than ten minutes. Clouds, flowers, and the sunset are too awesome to describe with just a few words, to someone who has never seen them.
So how would you describe God for someone who have never seen him? The old prophet Isaiah took on this task. Read his words. “Holy, holy, holy is the Lord of hosts. The whole world is full of his glory.”
In the Hebrew language, repetition performed the role of our modern highlighter. Repetition stood for emphasis. No verse ever describes God as “strong, strong, strong” or as “wise, wise, wise.” The only description given three times was “holy.”
The Hebrew word is qadosh, meaning “cut off, separate.” In other words, Isaiah is saying that God is unique. He is like no other. And he calls us to holiness, as well.
Sure, you’re smart, beautiful, and funny. But are you holy?
“Be holy because I am holy” (1 Peter 1:16).
