What Is the Glory of God?

It's easy for phrases we use a lot to become emptied of their meaning. John Piper doesn't want that to happen to "the glory of God."

What is the glory of God?

The glory of God is the holiness of God put on display. That is, it is the infinite worth of God made manifest. Notice how Isaiah shifts from “holy” to “glory”: “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!” (Isaiah 6:3). When the holiness of God fills the earth for people to see, it is called glory.

The basic meaning of holy is “separated” from the common. Thus, when you carry that definition all the way to the infinite “separation” of God from all that is common, the effect is to make him the infinite “one of a kind”—like the rarest and most perfect diamond in the world. Only there are no other diamond-gods. God’s uniqueness as the only God—his God-ness—makes him infinitely valuable, that is, holy.

The most common meaning for God’s glory in the Bible assumes that this infinite value has entered created experience. It has, as it were, shined. God’s glory is the radiance of his holiness. It is the out-streaming of his infinite value. And when it streams out, it is seen as beautiful and great. It has both infinite quality and infinite magnitude. So we may define the glory of God as the beauty and greatness of God’s manifold perfections.
