There are some words that we read in our Bibles that we assume we understand what they mean. Sometimes we do not know what they mean, but because of the sheer repetition of them, they become almost invisible to us as we learn to read past them. A prime example of that would be the word HOLY. What does HOLY mean? In this message, Dr. Sproul gives us that answer as we find out why the angels sing "Holy, Holy, Holy."
