WHAT DOES "SET APART" MEAN?

Jim Book: "My fear today is that many churches are dying because the average person in their pews have no idea what it means to be 'set apart' from the defilements of this world. The church is many areas is so worldly minded, it is difficult to see any real separation from the world. We dress as provocatively as the world. Our entertainment is as debauched as the world, and we are as preoccupied with the same secular trinkets as is the world."
