At the beginning God expressed himself.
That personal expression, that word, was with God, and was God, and he existed with God from the beginning.
All creation took place through him, and none took place without him.
In him appeared life and this life was the light of mankind.
The light still shines in the darkness
and the darkness has never put it out.
(John 1:1-5 Phillips)
I’ve heard that glory is however God chooses to express himself.
When the light of Jesus shines in dark places, when forgotten dreams and shattered hopes spring to life, when love flickers in a heart grown cold, when the beauty of creation glows in unexpected places, he is showing us his glory.
