Sure we do. Jesus said Satan was cast out of God's heaven and now he is the prince of the power of the air who works in the disobedient.
Satan is a gorgeous being, but with the nature of a poisonous snake.
Luke 10:17 And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name. 10:18 And he said unto them, I beheld Satan as lightning fall from heaven. 10:19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you. 10:20 Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.
He was referring to Satan's "power" over Israel.
Matthew thru Early Acts had been
a foretaste of Israel's promised "world to come..."
Matthew 12:23 And all the people were amazed, and said, Is not this the son of David? 12:24 But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils. 12:25 And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand: 12:26 And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand?
Satan's kingdom refers to his rule, or power over Israel, there...
Matthew 12:27 And if I by Beelzebub cast out devils, by whom do your children cast them out? therefore they shall be your judges. 12:28 But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you. 12:29 Or else how can one enter into a strong man's house, and spoil his goods, except he first bind the strong man? and then he will spoil his house.
But Satan's kingdom, or rule, or power, was still very much in effect as a would be counter to the Lord's, there...
Think "power, or prince, or rule, or ruler over."
Notice in the very next passages that it was still in effect as a would counter to the Lord's power...
Matthew 12:30 He that is not with me is against me; and he that gathereth not with me scattereth abroad. 12:31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. 12:32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world,
neither in the world to come.
The writer of Hebrews continues that exact same frame of reference during his writing of the following to his own...
Hebrews 2:1 Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip. 2:2 For if the word spoken by angels was stedfast, and every transgression and disobedience received a just recompence of reward; 2:3 How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; 2:4 God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will? 2:5 For unto the angels hath he not put in subjection the world to come, whereof we speak.
Obvioulsy, Satan's kingdom, rule, or power as an opposition is evident there as still an issue when the writer of Hebrews pens that to his own..
Likewise in the following concerning the Body, after Israel's Believing Remnant were sealed by the Lord and the rest of Israel was concluded by the Spirit as having continued in the Uncircumcision of heart of their forefathers against the Law, at the end of Acts 7.
Concerning the Body - on the one hand we read...
Colossians 1:12 Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light: 1:13 Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: 1:14 In whom we have redemption through his blood, even the forgiveness of sins: 1:15 Who is the image of the invisible God, the firstborn of every creature: 1:16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: 1:17 And he is before all things, and by him all things consist.
On the other, we read...
Ephesians 6:10 Finally, my brethren, be strong in the Lord, and in the power of his might. 6:11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. 6:12 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. 6:13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
And then there is what all both of those distinctions mean this side of "that which is perfect" - which is another study in itself.
