Paul spends the next four years as a prisoner — two of them in Caesarea and two more under guard in Rome. It looks like the end of his usefulness. Four of his letters come out of it. Ephesians · Colossians · Philemon · Philippians

The arrest

Paul is recognized in the temple courts and a rumor spreads that he has brought a Gentile inside the barrier — a capital offense. The crowd drags him out and is beating him to death when the Roman garrison comes down the stairs and takes him into custody. He asks permission to address the mob, and does, in their own language.

They listen until he mentions being sent to the Gentiles, and then the shouting starts again. When he is about to be flogged for information, he mentions almost casually that he is a Roman citizen by birth, which stops proceedings immediately. Learning that more than forty men have sworn not to eat until they have killed him — a plot his nephew overhears and reports — the commander sends him to Caesarea overnight with a heavy escort.

Acts 21:15–23:35

Felix, Festus, Agrippa

What follows is two years of Roman legal process, which is largely two years of nothing happening. Felix hears the case, is interested enough to send for Paul often, hopes for a bribe, and leaves him in prison when he is replaced. Festus inherits the problem, and when it becomes clear he may be sent back to Jerusalem to be tried — and killed on the way — Paul exercises his right as a citizen and appeals to Caesar.

Before he is shipped out, King Agrippa asks to hear him. Paul tells the Damascus road story again, and Agrippa’s reply — in so short a time would you persuade me to be a Christian? — has been read as sarcasm and as something closer to being moved. Agrippa’s verdict to Festus afterward is that the man could have been set free if he had not appealed.

Acts 24:1–26:32

The voyage

Luke was aboard, and it shows. The account of the voyage to Rome is one of the most detailed descriptions of ancient seafaring that survives — the wrong season, the argument about sailing on, the northeaster, running the ship under a small island to get the boat aboard, throwing the cargo and then the tackle over the side, fourteen nights of drifting, taking soundings in the dark, and finally running her aground and everyone getting ashore, some swimming, some on planks.

They winter on Malta, where the islanders show them great kindness. Then on to Rome, where Paul lives two years in his own rented house with a soldier to guard him, receiving anyone who comes.

Acts 27:1–28:31

The prison letters

Ephesians, Colossians, Philemon and Philippians — about A.D. 60–62. The first three appear to have gone out together, carried by Tychicus. Colossians answers a local teaching that was adding rules and mystical experiences to Christ. Ephesians covers similar ground in a broader, calmer key, and reads more like a circular letter than a reply. Philemon is a private note, barely a page, asking a slave owner to take back a runaway named Onesimus — no longer as a slave, but as a brother.

Philippians came later, after the Philippians had sent him money, and it is the warmest of the four. The man writing about joy from a rented cell under guard is not being sentimental; he is being specific about where the joy came from.

How Acts ends

It stops. Two years in Rome, preaching without hindrance — and no verdict, no execution, no ending. That has puzzled readers for centuries. The simplest explanation is that Luke wrote it at that point, before the outcome was known, and that the outcome is the next part of the story.

Everything after this comes from the letters themselves and from later tradition, not from Acts. That is the next part.
