1Pt 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.
*This is a NT verse for the instruction of the present church and body of Christ and correlates with that which is recorded in (Job 1:7,2:2) where Satan is seen as going to and fro and walking up and down in the earth.
In (Rev 20:2) he is the dragon, that old serpent, the devil and Satan.
In (Lk 10:18) Jesus said that He beheld Satan fall as lightning from heaven, who was cast out unto the earth in (Rev 12:9). The verb 'beheld' is an imperfect tense that is unfolding with progressive results. These two verses give us a reference of a past completed act of Satan falling from heaven with a future application that progressively unfolds in the plan of God that effects time and place. There is no indication that Satan is presently bound in the bottomless pit, for that is future in (Rev 20:1-3), but rather has been been cast out and bound from his active exalted position in heaven... as an anointed cherub that covereth being set upon the holy mountain of God (Ez 28:14)... to the atmosphere above the earth (Eph 2:2) and later upon the earth (Rev 12:9).
*Satan is cast out of the atmosphere of heaven above the earth to the inhabitance of the earth in (Lk 10:18, Rev 12:9) and later is bound by a angel to the bottomless pit in (Rev 20:1-3). The angel came down from heaven (locative - Rev 20:1) to bind and chain the Devil that was upon the earth (locative), who had previously ruled from the air and atmosphere above it (Eph 2:2). Satan had to be cast upon the earth so that he could later be bound by the angel which is all future because the revelation and vision given to John in (Rev 20) was future and this was written some (95 years) after the ascension of Christ. There is an angelic conflict (Jude 1:9, Dan 10) that has and is taking place in the atmosphere and Satan has to be brought low and spoiled from his reigning position in the atmosphere in order to be bound and chained in the bottomless pit.
*When Jesus Christ ascended into heaven, He spoiled the principalities and powers, meaning that He stripped them off his body as He was ascending and made an example (open shew) of them as He triumphed over them and went right through their clutching grasp (Col 2:15).
To believe at present that Satan has been bound and chained to the bottomless pit (Rev 20:3), is to distort the scriptures by dislocating them from their arranged position. Those scriptures that provide the church with instructions concerning the present activity of the dragon, that old serpent, the devil and Satan would be obsolete and we would have no need to put on the whole armour of God that we might be able to stand against the wiles of the devil (Eph 6:11). 'wiles of the devil' are those deceitful, cunning and crafty tricks of the devil.
Eph 6:10-18
10 Finally, my brethren, be strong in the Lord, and in the power of his might.
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.
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.
14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15 And your feet shod with the preparation of the gospel of peace;
16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
*If Satan (the Devil) is bound at present, having no authority of power here on the earth, then we, as members of God's church and body, have no need to be concerned or to practice putting on the whole armour of God. Why is the above passage present in the scriptures to instruct believers that make up the church after the ascension of Christ, if Satan is bound and chained in the bottomless pit already? Here are others passages that relate to Satan being active in the NT church...
Acts 5:3, 26:18, 1Cor 5:5, 7:5, 2Cor 2:11, 4:4, 11:14, 12:7, Eph 4:27, 1Thes 2:18, 1Tim 1:20
So whoever believes that Satan has already been bound, also believes that we are in the 1,000 reign of Christ on earth. Those that believe in this manner are out of joint with the order of events that take place concerning the revelation and vision that was given to John when on the Isle of Patmos (Rev 1:9).
