Satanism itself is an evil cult that has always been part of the depraved mass of society, but is currently on the increase. Satanists believe that the Creator God has withdrawn from the world, never intervening anymore in its affairs, and that the Son of God who has been given control of the earth in the Creator's absence is Satan, the god of this world (described in 2 Corinthians 4:4 as the god of this passing age). Jesus tried to destroy Satan's plan for the world, but it is, according to their belief, Satan that will attain the final victory. They participate in depraved rites and through psychic practices open themselves to the influence of satanic powers. The motives of its practitioners are mixed.
I have no doubt that the practitioners of Satan worship are soon assaulted by evil forces, an infestation that shows itself in a progressive deterioration of the person's character. Deceitfulness, perverse sexual behavior, stealing, and increasing destructiveness are typical features of this break down of the personality. To the rationalist all these changes can easily be attributed to fear and the general atmosphere of perversion that lies around zealous practitioners, but in practice there is usually a more concentrated focus of psychic assault in such cases, in addition to the psychological confusion that is drawn to the surface by the eruption of fear and hatred.
It is the social misfit and emotional cripple who are attracted bizarre activities of this kind. They are sad specimens of disordered humanity who seek power to affirm their shaky confidence. What they are really seeking is understanding and affection, but there are not many agencies who provide these needs, at least in a form that accepts the person as he is without imposing a rationalistic or a sectarian religious style of thinking upon him.
