All else begins. He alone always was. All else depends. He alone is self-sufficient. And therefore the holiness of God is synonymous with his infinite value.
Diamonds are valuable because they are rare and hard to make.
God is infinitely valuable because he is the rarest of all beings and cannot be made at all nor was he ever made. If I were a collector of rare treasures and could somehow have God, the Holy One, in my treasury I would be wealthier than all the collectors of all the rarest treasures that have ever lived. His holiness is his immeasurable worth and value. Nothing can be compared with him, for he made everything, and whatever glory renders a created thing valuable is found one million-fold in the Creator. His glory covered the heavens, and the earth was full of his praise.
