Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience
2 Corinthians 4:4
In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
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.
Job 1:6-12—Subject to God, freedom within bounds
Now there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them.7 And the Lord said unto Satan, Whence comest thou? Then Satan answered the Lord, and said, From going to and fro in the earth, and from walking up and down in it.8 And the Lord said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?9 Then Satan answered the Lord, and said, Doth Job fear God for nought?
10 Hast not thou made an hedge about him, and about his house, and about all that he hath on every side? thou hast blessed the work of his hands, and his substance is increased in the land.11 But put forth thine hand now, and touch all that he hath, and he will curse thee to thy face.12 And the Lord said unto Satan, Behold, all that he hath is in thy power; only upon himself put not forth thine hand. So Satan went forth from the presence of the Lord.
Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Gospel limits Satan by being the vehicle that ushers in his final defeat
And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:14 I will ascend above the heights of the clouds; I will be like the most High.15 Yet thou shalt be brought down to hell, to the sides of the pit.
And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name.18 And he said unto them, I beheld Satan as lightning fall from heaven.
