H.G. Wells’ 1898 novel, The War of the Worlds opens with these words: "No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied… With infinite complacency men went to and fro over this globe about their little affairs … Yet across the gulf of space… intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us.” This is an apt description of the threat faced by many Christians in the 21^st century, especially concerning the area of sexual morality and sin.
