You need the WT...but it doesn't need you:
Watchtower 50 1/15 p. 26 par. 22 Who Will Share in the Final Witness?
"Jehovah’s visible organization can use you, but can get along without you too. But you cannot get along without it. Fruitless ones are eventually pruned off and never missed..."
.
WT calls all JWs "sheep", but here's what it thinks about sheep:
"Sheep are interesting creatures — docile, timid, and often plain stupid" --Awake! 3-8-93, p 15
