No disrespect intended with this post because of the funny picture, this is a genuinely shocking question:
Dr. Billy Graham once made a critical analysis of the Church systems in general and came to the conclusion that "The Holy Spirit could leave the church and it would go right on doing 90% of what it was doing; and NOT KNOW that the Holy Spirit had left."
So, it begs the question:
If the Holy Spirit was to leave your church, how much activity would just carry on?
