Eph 6:11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. 12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
As we can see the battle is against the devil and principalities of darkness - and not flesh and blood man/politicians/reprobates.
The politicians in western nations have gone over to anti-Biblical anti-Christian and immoral idologies during these recent decades. Why? Because of Satan's activities, evil and sin. These politicians are under the dominion of sin, blind to the truth and completely unable to discern truth, which is a spiritual disposition which only Christians are given to embrace.
John 1:17 For the law was given by Moses, but grace and truth came by Jesus Christ.
John 8:32 And ye shall know the truth, and the truth shall make you free.
The alternative; John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him.
