▁the ▁kingdom ▁of ▁God ▁is ▁upon ▁you " ▁( M att . 1 2 : 2 8 ; ▁Luke ▁ 1 1 : 2 0 ). ▁ ▁Evangel ical ▁Christian ▁trad itions ▁believe ▁that ▁Sat an ▁and ▁his ▁min ions ▁exercise ▁significant ▁influence ▁over ▁this ▁world ▁and ▁its ▁power ▁structures . ▁A ▁host ile ▁real m ▁in ▁conflict ▁with ▁the ▁kingdom ▁of ▁God ▁is ▁recorded ▁in ▁the ▁Bible ▁by ▁the ▁Apost le ▁John , ▁" the ▁whole ▁world ▁is ▁under ▁the ▁control ▁of ▁the ▁evil ▁one " ▁( 1 ▁John ▁ 5 : 1 9 ) ▁and ▁by ▁Jesus ▁who ▁referred ▁to ▁Sat an ▁as ▁" the ▁prince ▁of ▁this ▁world " ▁( John ▁ 1 2 : 3 1 ; ▁ 1 4 : 3 0 ; ▁ 1 6 : 1 1 ), ▁which ▁may ▁point ▁to ▁the ▁concept ▁of ▁Territ orial ▁Sp ir its . ▁ ▁Paul ▁elabor ates ▁on ▁demon ic ▁hierarchy ▁in ▁E ph es ians ▁ 6 ▁where ▁he ▁also ▁mentions , ▁by ▁way ▁of ▁met ap hor , ▁those ▁qual ities ▁needed ▁for ▁defense ▁against ▁them . ▁Two ▁of ▁those ▁articles , ▁the ▁hel met ▁of ▁Salv ation ▁and ▁the ▁breast plate ▁of ▁R igh te ous ness , ▁are ▁also ▁mentioned ▁in ▁the ▁book ▁of ▁Isa iah . ▁ ▁It ▁is ▁also ▁believed ▁that ▁Sat an ▁occup ies ▁a ▁temporal ▁existence ▁when ▁the ▁Apost le ▁Paul ▁refers ▁to ▁him ▁as ▁" the ▁god ▁of ▁this ▁age " ▁( 2 ▁Cor . 4 : 4 ).
