This question reminded me of a 32 page booklet on exactly this subject, published in 1995.
Here is its introduction (my emphasis) to The Young Revolutionaries:
To most, those living in Jesus’ day were ancient old men, long, white beards flowing down over their chests, stooped, rheumy-eyed, sad. Millions think of them as ancient sages, soft-spoken “saints,” standing around with hands forming steeples, and a faraway gaze in their sorrowful eyes. All this is nonsense, of course, but it is the concept projected by religious art, statuary, and false teaching. Actually, the disciples of Christ were young men, living in the “here and now,” fully expecting a dramatic overthrow of government, and a violent revolution in their immediate lifetimes!
It would have been cruel to have told them. How much zeal would you and I have for the work of God—the work of witness and warning for our fellowman of impending tribulation, of the heavenly signs, and of the Day of the Lord—if we thought none of it would take place for another 2000 years?
How much enthusiasm would we put into a perceived political or social cause if we thought it would not be realized until twenty generations later? How dedicated, how committed, how determined would you be, if you thought you were working for a new world order that would not materialize until 2000 years after you were dead?
The disciples of Jesus Christ, still tingling with wonderment and astonishment over Christ’s many miraculous appearances following His resurrection, asked Him a question which bears careful scrutiny and understanding.
As He stood before them, He commanded them to “wait for the promise of the Father, which ye have heard of Me. For John truly baptized with water: but ye shall be baptized with the Holy Spirit not many days hence” (Acts 1:4,5).
It is likely they didn’t understand this statement any more than they had many of His enigmatic pronouncements, for they were still carnal. Willing, enthusiastic, but carnal, lacking deep, spiritual perception.
The proof of their lack of understanding follows quickly.
“When they therefore were come together, they asked of Him, saying, ‘Lord wilt Thou at this time restore again the kingdom to Israel?’” (Acts 1:6).
Their question deserves close scrutiny. They did not ask whether He would come to rule the world, which was the very thing He had continually emphasized. They asked nothing about Rome, or Dacia, or Carthage, or Bithynia, or Cappodocia, or Greece. They asked nothing about India, or Britannica, or Germanica.
There was no conception in their minds of a world-ruling Kingdom of God!
No, their minds conceived only of an Israelitish kingdom, restored to its borders of greatest advancement under David and Solomon! They specified “the kingdom,” meaning the national entity of Israel the way it had been hundreds of years previously, with borders from modern-day Iraq to Egypt.
They asked if He would restore “the kingdom” to Israel!
It was their land, their lives, their families, and their immediate environment and social conditions about which they were concerned. Their question addressed only their own immediate future, as viewed from a purely nationalistic and patriotic point of view.
His answer was the kindest response He could have given them.
“And He said unto them, It is not for you to know the times or the seasons, which the Father hath put in His own power, But ye shall receive power, after that the Holy Spirit is come upon you: and ye shall be witnesses unto Me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth” (Acts 1:7,8).
Even this they did not understand fully, and would not understand it until the power of which Christ spoke was given to them.
