1.) Paul stated the end of the ages had come upon them in 1 corinthians 10:11.
2.) Paul stated the present form of the world was passing away in 1 corinthians 7:31.
3.) Paul stated that Satan would “soon” be crushed in Romans 16:20.
Now, the traditional Amil typically claims it has been the “last days” or “end of the ages” for the last 2,000 years and that “soon” doesn’t mean literally soon, in regards to Christ’s coming. So, for consistency sake, I see no reason for the Amil futurist not to claim Satan’s little season has been ongoing for last 2,000 years.
I see an obvious reason for that which is that 2,000 years is not a "little season".
It's one thing to believe that the thousand years is figurative and has been ongoing for almost 2,000 years, as Amils do, but it's another thing altogether to try to claim that Satan's little season has been ongoing for almost 2,000 years.
However, It would seem inconsistent for the Amil futurist to claim “the last days” have been going on for the last 2,000 years, and “soon” in regards to Christ’s coming doesn’t literally mean soon, BUT Satan’s little season is literally short.
I disagree. The Greek word translated as "little" in "little season" is used to refer to a literally small number, so there is no basis whatsoever for thinking that Satan's little season will be anything except for a literal small amount of time. We don't know how much time it is, but I'm certain that 2,000 years would not qualify as a little season.
But, the Greek word translated as "soon" ("shortly", "quickly") in reference to His coming is "tachos" (Strong's G5034) and refers to how fast He will come once He does come. He will quickly descend from heaven and the bodies of His people will be changed quickly (1 Cor 15:50-54) and He will destroy His enemies quickly without delay. Satan will be crushed quickly without delay when he is cast into the lake of fire.
That word is used in this passage:
Luke 18:7 And will not God bring about justice for his chosen ones, who cry out to him day and night? Will he keep putting them off? 8 I tell you, he will see that they get justice, and
quickly (Greek: tachos). However, when the Son of Man comes, will he find faith on the earth?”.
This passage is not saying that God would literally bring about justice for His chosen ones in a short amount of time from when Jesus was speaking, but rather is saying that He will for certain bring about justice and when the time comes for that to happen, it will happen quickly.
That is how the word should be understood in any verses that talk about Jesus coming soon or quickly. It will happen so fast that it will be "as lightning that comes from the east is visible even in the west" (Matt 24:27).
