The Fullness of His Glory

It's been a busy day, but I managed to read something good. The article is about how an awe for God and an appreciation of His glory transforms our approach to life. But there was one particular line that struck me:

"If you are not committed to loving gospel community, you will minister out of frustration and discouragement, displaying God's glory in an abstract form, but not in its living, life-changing vitality."

Quite obvious, so why don't we realise and understand?
