The sphere of the Spirit of God is the Truth; the sphere of the spirit of the world embraces everything that is not the truth.  His [Satan’s] method of gaining his end is deception.  He is the one who “deceives the whole world” (habitable earth) Rev. 12:9.

The world itself is a gigantic and complicated deception, whose promises are not fulfilled, whose honors quickly fade, whose prizes are cheats, whose pleasures do not satisfy, whose riches corrupt, whose praises are insincere ... in which, in a word, the real value of everything is disguised and misrepresented.
