“To say that God is holy is to say that he is set apart, distinct from us. And because of His set apart-ness, there is no way we can fathom all of who He is. To the Jews, saying something three times demonstrated it perfection, so to call God ‘Holy, Holy, Holy’ is to say that He is perfectly set apart, with nothing and no one to compare Him to. That is what it means to be ‘holy’.
Many Spirit-filled authors have exhausted the thesaurus in order to describe God with the glory He deserves. His perfect holiness, by definition, assures us that our words can’t contain Him. Isn’t a comfort to worship a God we cannot exaggerate?”
