Why this Form of Worship?

 
"And so, I find it well to come
For deeper rest to this still room,
For here the habit of the soul
Feels less the outer world's control.
The strength of mutual purpose pleads
More earnestly our common needs.
And from the silence multiplied
By these still forms on either side,
The world that time and sense have known
Falls off and leaves us God alone."
- John Greenleaf Whittier (1807-1892), member, Amesbury, Mass. Meeting
 
"For when I came into the silent assemblies of God's people, I felt a secret power among them which touched my heart; and as I gave way unto it, I found the evil weakening in me and the good raised up."
- Robert Barclay (1648-1690), eminent Quaker theologian and author
 

Whittier and Barclay pretty much sum it up, but here are some other people's thoughts:
