Justin Buzzard keeps posting great quotes. Here is another,
Martyn Llyod Jones reporting after his six months away from preaching due to illness, in which he simply attended church services:
"My general impression is that most of our services are terribly depressing! I am amazed people still go to church; most who go are female and over the age of forty. The note missing is 'joy in the Holy Ghost'...There is no life, no power! We of all people ought to have it. Joy and power are intimately related. One without the other is spurious."
