Andrew Holden's "Jehovah's Witnesses: Portrait of a Contemporary Religious Movement" book (pg 92-3) noted the stark contrast between imagery in their literature of the paradise ("deliriously happy faces with surrounding emerald green slopes, clear blue skies and bright sunshine ... an exaggerated vesion of contentment") with life on the outside ("pictures of people being murdered, thieves breaking into houses, couples acting promiscuously, all of which show life outside the organisation as debased and riddled with moral danger. These images are presented in dark colour and portray characters with unattractive features.")
He added: "This contrast of salvation on the inside and risk on the outside implies that not only can there be nothing in between the two systems but that morality cannmot exist outside the Watch Tower community."
