Amo - You might happen to be one of those who do not acknowledge scripture's description of the tendency to deception lurking the human heart since birth, (Ps. 58:3 - "The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies."). If you are one of those that reject this concept, it is probably impossible to admit that any current manifestations of wickedness and deceit committed in this New Covenant Age are credited to MAN ALONE - NOT due to any supposed Satanic or demonic operation in the world.
I believe the following is the main reason God eradicated the presence of the evil spirit realm from this planet since the close of AD 70: to show mankind just what level of wickedness his own spirit is capable of, even WITHOUT the devil or demons around to "beguile" him. It's a humiliating truth: our predisposition to commit evil is every bit as bad or EVEN WORSE than Satan's ever was, because our sins are committed against God's mercy bestowed on us. Satan and the demonic world were not given the blessings of God's intervening grace, as humans were, so our offenses against God are even more egregious than his.
In your comment #90 above, Amo, the entire text of Revelation 12 that you presented is a repetition of first-century history, encompassing Christ's birth, resurrection, and the loosing of Satan the Dragon after Christ's ascension by his being cast out of heaven into the earth (John 12:31 and 14:30). It was then that his "short time" of persecuting the church in great wrath after Pentecost began. This was the time he made war on the resurrected First-fruits remnant of the woman's seed that were raised along with Christ - the 144,000 "remnant" of Matthew 27:52-53 saints. The history of this persecution period starting in full fury the very day Stephen was martyred is recorded for us in the book of Acts. Revelation 12 is a synopsis of Acts' history of the flood of early church persecution, including Saul's / Paul's part in it.
In your comment #91, Amo, there is NO WAY this beast empowered by Satan is a future one to us, because of the "seat" or "throne" (thronon) of Satan's which was given to that first beast from the sea. Revelation tells us that Satan's "seat" was at PERGAMOS (Rev. 2:13). This idolatrous city was the center of the Pergamum kingdom on the Asian continent, which was GIVEN entirely to the ROMAN REPUBLIC in 133 BC by a dying King Attalus III. He had no heir to pass his Pergamum kingdom to, and he knew the Roman republic was powerful enough to protect the Pergamum kingdom from descending into civil strife, or from being invaded by enemies.
Therefore, since the Roman empire exists no more today, which once had this "seat" or "throne" of Satan in Pergamos given to it, this prophecy is on the list of fulfilled ones. It also means that it was the Roman empire which was represented by the Sea Beast of Rev. 13:1-2. Under Nero's reign, there were exactly 42 months of heavy persecution (Rev. 13:5-7) launched by the Sea Beast against the Christians. This "fiery trial" of Christian sufferings that Peter said was then happening to his readers (I Peter 4:12 - written in AD 65) was first launched in late AD 64 after the fire of Rome was blamed on the Christians.
You state that Preterist's claim that "all the world" doesn't mean "all the world". Well, when one looks at the Greek, there IS a difference between "All the WORLD" (kosmos or oikoumene - which can be either the globe or the known habitable world), and "all that dwell upon the EARTH" (tes ges - which is the "land" of Israel usually). Revelation 12:12 also makes a distinction when it comes to "the inhabitants of the EARTH" (land of Israel) compared to "the inhabitants...of the SEA" (which usually refers to Gentile countries). Satan was busy deceiving ALL these inhabitants of the earth AND of the sea in that "short time" of his, from AD 33-66. I try to follow the Greek whenever the context makes a difference between each of these terms, not just read into it what I want it to say. In this case, the English is rather generic, compared to the more precise Greek terms.
And your comment #92 about the timing of " the latter times"... the same "last days" that Peter identified as their own contemporary times when the Spirit was poured out in fulfillment of the Joel prophecy - these "last days" were the same as "these last days" that were then present in Hebrews 1:1-2. Jude 18 also agrees that the "mockers" predicted by the apostles to come in "the last time" were at that moment already operating among the church in his day.
The time clock for the "last DAYS" had progressed to "the LAST *HOUR*" by the time I John 2:17-18 was written. If the countdown had progressed from the "last days" to "the last HOUR" from AD 33 up until John's writing, it stretches all bounds of reason to say that "the last HOUR" should still be pending for almost 2,000 years now - especially when John's revelation said that "the time is AT HAND" (or present) to those he was addressing, for all his written prophecies to be fulfilled.
And your comment #93: I have covered the historic record of fulfillment for this II Thessalonians 2 prediction in a couple posts elsewhere. One from May 2017 was called "The 'Man of Lawlessness' was a first - century Zealot". Another was my comment #28 in the post called "Why a new temple is not needed in physical Israel" back in Nov. 2016. Not sure how you presume we have said that there is "no more deception and delusion in the world", and that "all are now saved".
Never stated either of those things. As I've said above, Satan's presence is not a prerequisite for deception or sin to occur in the world. We are equipped to do this ourselves from birth.
And your comment #94: the apostles gave THAT GENERATION warnings and descriptions of battles with the Satanic realm because those epistles were written when it was still Satan's "short time" and "little season" of being loosed in those days from AD 33-AD 66. The "armor of God" found in Ephesians 6 (written around AD 62-64) was still needed for Christians to combat "the wiles of the devil" up until he was imprisoned in Jerusalem in Revelation 18:2 and was cast into Jerusalem's Lake of Fire in Revelation 20:10.
The believers in those days were alerted about their soon-coming release from Satan's oppression. Romans 16:20 (written around AD 60) says that the God of peace would "bruise" or "crush" (suntribo) Satan himself under THEIR feet "SHORTLY". A time span from AD 60 until Satan's and the devils' imprisonment in Jerusalem in AD 66 qualifies as "shortly". On the contrary, if Romans 16:20 was referring to a time span of 2,0000-plus years and still counting, that is NOT crushing Satan "SHORTLY", by any stretch of the imagination. And Paul knew very well what the relative sense of the word "shortly" meant, since he used it in I Timothy 3:14 to say that he wanted to come unto Timothy "shortly" at that time.
