I also dont believe that Satan was done away with when Ephesians and most of the Apostolic Record was written, until Revelation, but he could have been bound with-in the subcontext of the time alloted for the Gospel to spread to the ends of the world before the end of the Age of Material REligion which Jesus replaces - before the end had come, upon the nation of Israel.
John warned the people about the wrath to come,
Luke 3
New International Version
John the Baptist Prepares the Way
3 In the fifteenth year of the reign of Tiberius Caesar—when Pontius Pilate was governor of Judea, Herod tetrarch of Galilee, his brother Philip tetrarch of Iturea and Traconitis, and Lysanias tetrarch of Abilene— 2 during the high-priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the wilderness. 3 He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins. 4 As it is written in the book of the words of Isaiah the prophet:
“A voice of one calling in the wilderness,
‘Prepare the way for the Lord,
make straight paths for him.
5 Every valley shall be filled in,
every mountain and hill made low.
The crooked roads shall become straight,
the rough ways smooth.
6 And all people will see God’s salvation.’”[
a]
7 John said to the crowds coming out to be baptized by him, “You brood of vipers! Who warned you to flee from the coming wrath? 8 Produce fruit in keeping with repentance. And do not begin to say to yourselves, ‘We have Abraham as our father.’ For I tell you that out of these stones God can raise up children for Abraham. 9 The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.”
I believe this was a foretelling that Jews had known about in which Malachi promised to come when John prepared the way for Jesus in the Spirit of Elijah wasn't it?
Malachi 4
New International Version
Judgment and Covenant Renewal
4 [
a]“Surely the day is coming; it will burn like a furnace. All the arrogant and every evildoer will be stubble, and the day that is coming will set them on fire,” says the Lord Almighty. “Not a root or a branch will be left to them. 2 But for you who revere my name, the sun of righteousness will rise with healing in its rays. And you will go out and frolic like well-fed calves. 3 Then you will trample on the wicked; they will be ashes under the soles of your feet on the day when I act,” says the Lord Almighty.
4 “Remember the law of my servant Moses, the decrees and laws I gave him at Horeb for all Israel.
5 “See, I will send the prophet Elijah to you before that great and dreadful day of the Lord comes. 6 He will turn the hearts of the parents to their children, and the hearts of the children to their parents; or else I will come and strike the land with total destruction.”
So because of these things, the bounding of Satan would have to come about with-in that Generation. And not some 1000 year literal interpertation as many subscribe too.
As Jesus stated here to the 4 disciples he had been talking to openly and honestly with full bluntness of saying with-in a generation, this is a choice on individuals to choose to decide does Jesus message for those people in that day, all apply to us now today, if he has promised to come get them first? One day we will die pass on and go on to be judged and placed either outside or inside the kingdom from my understanding, but the wrath of God -
the Wrath of God was for those disobedient who ended up having the Son of God killed on the cross also from my perspecitve,
That destruction promised in Malachi came upon them with-in the generation I believe in 70Ad.
Matthew 24
3 As Jesus was sitting on the Mount of Olives, the disciples came to him privately. “Tell us,” they said, “when will this happen, and what will be the sign of your coming and of the end of the age?”
26 “So if anyone tells you, ‘There he is, out in the wilderness,’ do not go out; or, ‘Here he is, in the inner rooms,’ do not believe it. 27 For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man. 28 Wherever there is a carcass, there the vultures will gather.
29 “Immediately after the distress of those days
“‘the sun will be darkened,
and the moon will not give its light;
the stars will fall from the sky,
and the heavenly bodies will be shaken.’[b]
30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth[c] will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory.[d] 31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.
32 “Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. 33 Even so, when you see all these things, you know that it[e] is near, right at the door. 34 Truly I tell you, this generation will certainly not pass away until all these things have happened. 35 Heaven and earth will pass away, but my words will never pass away.
Even though there were many people who did not repent in that day in age, total destruction was promised to fall upon them and fire is alotted to in the message. Everything was destroyed by fire when Jerusalem was sieged even the Temple.
