'Against' in the Bible

in which you once walked. You were following the ways of this world [influenced by this present age], in accordance with the prince of the power of the air (Satan), the spirit who is now at work in the disobedient [the unbelieving, who fight against the purposes of God].

Have nothing to do with the barren unprofitable deeds of darkness, but, instead of that, set your faces against them;

Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.

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.
