Satan was NOT bound around 30AD in the Gospels

Revelation 20:1-3 is NOT fulfilled by Matthew 12:28-29, Mark 3:26-27, Luke 11:21-22

A "Full" Preterist (30-70AD Millennialist) may pronounce,

“We can boldly proclaim Satan has been defeated. All of these verses relate to Jesus being accused of working by the power of Satan/Devil & yet Jesus says He overpowered & bound the "strong man." Therefore, Satan was bound around 30AD during Jesus' ministry as recorded in the Gospels. These verses clearly establish this point:"

Mat 12:28-29 -- But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you. 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.
Mk 3:26-27 -- And if Satan rise up against himself, and be divided, he cannot stand, but hath an end. No man can enter into a strong man's house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.
Lk 11:21-22 -- When a strong man armed keepeth his palace, his goods are in peace: But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armour wherein he trusted, and divideth his spoils.
So, what the "Full" Preterist (30-70AD Millennialist) is saying, then, is this:
A) Around 27AD, Jesus explained the process by which He cast out an individual demon from an individual man, Mat 12:28-29, Mk 3:26-27, Lk 11:21-22.

B) Therefore, around 27AD Jesus fulfilled the predictive vision He would give John 35 years later foreseeing Satan being bound with a great chain and cast and sealed into the Deep (Abyss, Bottomless Pit) for a 1000 years.

Let's actually look up these & similar passages within their broader contexts to see if they support the claims of "Full" Preterists (30-70AD Millennialists):

Revelation 20:1-3 ~foreseen around 63AD in the predictive vision by Christ's exiled Apostle John; recalling that Rev 1:1 and Rev 4:1 inform that the Revelation predicts things still yet to come as of its writing
Then I foresaw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. 2 He laid hold of the dragon, that serpent of old, who is the Devil and Satan, and bound him for a thousand years; 3 and he cast him into the bottomless pit, and shut him up, and set a seal on him, so that he should deceive the nations no more till the thousand years were finished. But after these things he must be released for a little while. NKJV

But by broadening the portions "Full" Preterists (30-70AD Millennialists) cite, we can then see clearly that in each case Jesus identifies “the strong man” as simply the individual demon that is cast out of an individual man on an individual occasion so that the man may be saved. “That the strong man’s goods might be plundered” = “that the demon-possessed man might be rescued back to God, (saved).” Jesus is merely describing the process and Power by which He cast out an individual demon in order to redeem an individual man. Only someone desperate to force a contrived scheme upon the Scriptures would attempt to force a different conclusion.
For evidence, let’s look at the full context to see what Jesus was saying in those passages:
Matthew 12:22-30 ~preached around 28AD by Jesus, the Son of God
22 Then one man was brought to Him who was demon-possessed, blind and mute; and He healed him, so that the blind and mute man both spoke and saw. 23 And all the multitudes were amazed and said, "Could this be the Son of David?"
24 Now when the Pharisees heard it they said, "This fellow does not cast out demons except by Beelzebub, the ruler of the demons."
25 But Jesus knew their thoughts, and said to them: "Every kingdom divided against itself is brought to desolation, and every city or house divided against itself will not stand. 26 If Satan casts out Satan, he is divided against himself. How then will his kingdom stand? 27 And if I cast out demons by Beelzebub, by whom do your sons cast them out? Therefore they shall be your judges. 28 But if I cast out demons by the Spirit of God, surely the kingdom of God has come upon you. 29 Or how can one enter a strong man's house and plunder his goods, unless he first binds the strong man? And then he will plunder his house.
NKJV
Matthew 12:43-45 ~preached around 28AD by Jesus, the Son of God
43 "When an unclean spirit goes out of a man, he goes through dry places, seeking rest, and finds none. 44 Then he says, 'I will return to my house from which I came.' And when he comes, he finds it empty, swept, and put in order. 45 Then he goes and takes with him seven other spirits more wicked than himself, and they enter and dwell there; and the last state of that man is worse than the first. So shall [future] it also be with this wicked generation."
NKJV
Mark 3:20-27 ~preached around 28AD by Jesus, the Son of God
20 Then the multitude came together again, so that they could not so much as eat bread. 21 But when His own people heard about this, they went out to lay hold of Him, for they said, "He is out of His mind."
22 And the scribes who came down from Jerusalem said,"He has Beelzebub," and, "By the ruler of the demons He casts out demons."
23 So He called them to Himself and said to them in parables: "How can Satan cast out Satan? 24 If a kingdom is divided against itself, that kingdom cannot stand. 25 And if a house is divided against itself, that house cannot stand. 26 And if Satan has risen up against himself, and is divided, he cannot stand, but has an end. 27 No one can enter a strong man's house and plunder his goods, unless he first binds the strong man. And then he will plunder his house.
NKJV
Luke 11:14-26 ~preached around 28AD by Jesus, the Son of God
14 And He was casting out a demon, and it was mute. So it was, when the demon had gone out, that the mute man spoke; and the multitudes marveled. 15 But some of them said,"He casts out demons by Beelzebub, the ruler of the demons."
16 Others, testing Him, sought from Him a sign from heaven. 17 But He, knowing their thoughts, said to them: "Every kingdom divided against itself is brought to desolation, and a house divided against a house falls. 18 If Satan also is divided against himself, how will his kingdom stand? Because you say I cast out demons by Beelzebub. 19 And if I cast out demons by Beelzebub, by whom do your sons cast them out? Therefore they will be your judges. 20 But if I cast out demons with the finger of God, surely the kingdom of God has come upon you. 21 When a strong man, fully armed, guards his own palace (house), his goods are in peace. 22 But when a stronger than he comes upon him and overcomes him, he takes from him all his armor in which he trusted, and divides his spoils. 23 He who is not with Me is against Me, and he who does not gather with Me scatters.
24 "When an unclean spirit goes out of a man, he goes through dry places, seeking rest; and finding none, he says, 'I will return to my house from which I came.' 25 And when he comes, he finds it swept and put in order. 26 Then he goes and takes with him seven other spirits more wicked than himself, and they enter and dwell there; and the last state of that man is worse than the first."
NKJV

So again, these passages actually demonstrate that Jesus was merely describing the process and Power by which He cast out an individual demon in order to redeem an individual man on an individual occasion. Only someone desperate to force a contrived scheme upon the Scriptures would attempt to force a different conclusion. They certainly DO NOT equate with that anticipated by the Revelation's predictive vision granted 35 years later to the persecuted & exiled Apostle John:

Revelation 20:1-3 ~foreseen around 63AD in the predictive vision by Christ's exiled Apostle John; recalling that Rev 1:1 and Rev 4:1 inform that the Revelation predicts things still yet to come as of its writing
Then I foresaw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. 2 He laid hold of the dragon, that serpent of old, who is the Devil and Satan, and bound him for a thousand years; 3 and he cast him into the bottomless pit, and shut him up, and set a seal on him, so that he should deceive the nations no more till the thousand years were finished. But after these things he must be released for a little while. NKJV

CONCLUSION:
Contrary to the reckless claims of "Full" Preterists (30-70AD Millennialists) there remains to be seen any Bible evidence that: before the time, during the Gospels, Jesus bound Satan and cast & sealed him into the Deep (Abyss, Bottomless Pit) , thus beginning the 1000-year Millennium and fulfilling the predictive vision of Revelation 20:1-3 that Jesus was to give about 35 years later. Satan was NOT bound around 30AD in the Gospels, rather, Satan was very much loose and walking about as a roaring lion seeking whom he may devour, LINK.

Revelation 20:1-3 is NOT fulfilled by Matthew 12:28-29, Mark 3:26-27, Luke 11:21-22
