„In his great vision Isaiah perceives the voice of the seraphim even before he hears the voice of the Lord. What is it that the seraphim reveal? "Holy, holy, holy is the Lord of hosts; the whole earth is full of His glory."
Holy, holy, holy — indicate the transcendence and distance of God. The whole earth is full of His glory — the immanence or presence of God. The outwardness of the world communicates something of the indwelling greatness of God.
The glory is neither an aesthetic nor physical quality. It is sensed in grandeur, but it is more than grandeur. It is a presence or the effulgence of a presence.
The whole earth is full of His glory, but we do not perceive it; it is within our reach but beyond our grasp. And still it is not entirely unknown to us.“
