Acts 27: Paul is sent to Rome with two friends

Paul is a Roman citzen and a prisioner who appealed to Ceasar. He was in Ceasaria Martima that worked like a great Airport Hub with ships to many destinations. He had been previously many times there. Now, Paul is sent to Rome in a ship to Sidon with two friends: Luke and Aristarchus.
Although I live in large city, I don't have many friends. Paul was a prisioner with two leal friends but not only that, he was always gaining friends in his life. He was assigned under the care of the centurion Julius who became friend of Paul. They changed to an Egyptian ship full of wheat (a valuable cargo) which was destroyed in a shipwreck. In a way, Paul was taking care of all in the ship, he wanted them all alive.
Paul had a mission and he cared for people (not only Christians). No wonder he had friends.

Acts 26: The importance of resurrection to Paul

Paul is before king Agrippa (who knows the prophets and the Jewish tradition) and Festus (a Roman governor appointed to rule Judea). In today terms, Festus would be a "rational" guy who doesn't believe in resurrection. Thus, Paul is glad to be listened by king Agrippa who can understand the situation. In the book of Acts, it is the third time that the conversion of Paul is told. In his explanation, he is saying that he was like his enemies - who was also against the followers of Jesus; but he saw Jesus resurrected. He reread all the Tanakh and concluded that it was all about Jesus. Paul said to king Agrippa:

22-23 And everything I’m saying is completely in line with what the prophets and Moses said would happen: One, the Messiah must die; two, raised from the dead, he would be the first rays of God’s daylight shining on people far and near, people both godless and God-fearing.

Paul had a mission given by Jesus:

17-18 “‘I’m sending you off to open the eyes of the outsiders so they can see the difference between dark and light, and choose light, see the difference between Satan and God, and choose God. I’m sending you off to present my offer of sins forgiven, and a place in the family, inviting them into the company of those who begin real living by believing in me.’

For Festus, Jesus is dead; but for Paul, Jesus is not only alive, but He is the reason of his life.

Acts 25: Felix to Festus, change of the Roman governors of Judea

In Acts 25, Felix is substituted by Festus as the new governor of Judea. Although Felix kept Paul in prison for two years (expecting bribery), Festus decided to judge Paul as soon as he came into power. The enemies of Paul asked Festus to judge Paul in Jerusalem when in fact they had a plot to kill him; however Paul refused to go to Jerusalem and appealed to Ceasar, to be judged by the Ceasar Nero.
The king Herod Agrippa I had died in Acts 12, but now his son, Agrippa II received part of Agrippa I territories but not Judea. Festus (who was indeed ruling over Judea) invited Agrippa II to study the case of Paul because it was very difficult to document the accusation against him. Agrippa II realized that Paul was not guilt under the Roman law.
Paul belongs to the kingdom of God. It is very interesting how the kingdom of God grew and gained power in a very humble way; for instance, Paul uses the circumstances to present the kingdom of God when being judged.

Acts 24: Paul was good to Felix

Paul was taken to Ceasarea by commandant Claudius Lysias. There, he stood before Ananias and the procurator/governor Felix. Both Ananias and Felix were evil men. Felix was a slave who conquered a very high position. He was married to three queens, but in particular, Drusilla. Drusilla was married to king of Emesa but left his husband to marry Felix. Josephus hints that Felix hired the assassins of the High Priest Jonathan because Jonathan kept lecturing him on how to govern better. It is interesting how Paul addresses to Felix:

10 And when the governor had nodded for him to speak, Paul responded: “Knowing that for many years you have been a judge to this nation, I cheerfully make my defense, (...)

Paul was very respectful to Felix, but Felix even knowing that Paul had done nothing wrong kept him in prison, expecting some bribe from him.

We read:

24-26 A few days later Felix and his wife, Drusilla, who was Jewish, sent for Paul and listened to him talk about a life of believing in Jesus Christ. As Paul continued to insist on right relations with God and his people, about a life of moral discipline and the coming Judgment, Felix felt things getting a little too close for comfort and dismissed him. “That’s enough for today. I’ll call you back when it’s convenient.” At the same time he was secretly hoping that Paul would offer him a substantial bribe. These conversations were repeated frequently.

Thus, Paul didn't judge Felix as a bad man , however, he talked about how important is to have a right relation with God and this implies in a change of life. Felix stopped Paul because he was not interested in a relationship with God. That is: Paul didn't presuppose that Felix wasn't an elect of God. Despite Felix's character, Paul was good to Felix.

Acts 23: Paul in the Sanhedrin

The Sanhedrin is the council composed by the chief priest, and the leaders of Pharisees and Sadducees. At that time, the chief priest was Ananias. At Jesus time, the chief priest was Caiaphas, son in law of Annas (and not Ananias). Ananias was a violent, greedy and a volatile person that was assassinated by Jewish Zealots in 66.

1-3 Paul surveyed the members of the council with a steady gaze, and then said his piece: “Friends, I’ve lived with a clear conscience before God all my life, up to this very moment.” That set the Chief Priest Ananias off. He ordered his aides to slap Paul in the face. Paul shot back, “God will slap you down! What a fake you are! You sit there and judge me by the Law and then break the Law by ordering me slapped around!”

Thus, it is bizarre how the good man (Paul) was being judged by the bad man (Ananias). It reminds the judgement of Jesus.

6 Paul, knowing some of the council was made up of Sadducees and others of Pharisees and how they hated each other, decided to exploit their antagonism: “Friends, I am a stalwart Pharisee from a long line of Pharisees. It’s because of my Pharisee convictions—the hope and resurrection of the dead—that I’ve been hauled into this court.”

This statement caused a great confusion in the Sanhedrin because the Sadducees didn´t  believe in resurrection. Paul was taken out alive from the Sanhedrin by the Romans. The nephew of Paul (from his sister) heard a conversation where 40 Jews vowed to not eat until they kill Paul. Who were these Jews? Probably they ware Zealots. The Zealots couldn't think of gentiles (not as converted Jews), being accepted by the Lord. For them, Paul was betraying Israel.

Acts 22: Paul's discourse

The crowd in Jerusalem (near the temple) thought that Paul was some kind of helenist guy, that didn´t care about the Lord or the people of Israel. The proof to it was that they thought that Paul was leading some gentiles inside the inner courts of the temple (which would profane the temple). The crowd wanted to kill him, but when Paul was being rescued by the Roman commander in the stairs of of the Fortress of Antonia, he asked the commander to speak some words to the crowd (who was against him). 
His purpose was to explain that his acts were not against the Lord but by the opposite: his acts were in obedience to the Lord.
He began to talk in Aramaic, not in Greek. He began saying about his high level Jewish degrees (education, obedience to the tradition, etc.). In a way, he was far superior in Jewish tradition than the normal crowd. He explained that Jesus (who was crucified and cursed by the Lord) was indeed resurrected and alive.
We read:
21 And He/Jesus said to me, ‘Go! For I will send you far away to the Gentiles.’”
22 They listened to him up to this statement, and then they raised their voices and said, “Away with such a man from the earth, for he should not be allowed to live!”

Why the sentence in 21 made the crowd so angry? 
They always say the Gentiles as the uncleans while they were the chosen people of the Lord. It seemed very offensive to them that the Messiah would accept the Gentiles as his people.
And here I am: a gentile in 2026, that belongs to the Messiah, chosen by the Messiah.

Acts 21: Paul cared about the Jews to the point of risk his own life

Paul loved the gentiles and saw the Spirit changing their hearts. Paul also loved the Jews in the Jerusalem church and cared about what they were thinking. Some Jews were suspicious of Paul: wouldn't he be teaching the gentiles that the Mosaic law is useless? Paul had decided to go to Jerusalem and bring a great donation from the gentiles to them. However, the daughters of Philip, the Evangelist and Agabus were predicting that he would be captured there, so they were advising him not to go to Jerusalem. He said:

13 Then Paul replied, “What are you doing, weeping and breaking my heart? For I am ready not only to be bound, but even to die in Jerusalem for the name of the Lord Jesus.”

So he went there. He wanted to show that he was not against the Mosaic Law, but that backfired and he was captured.
People are very difficult to change opinion. I am reluctant to say things that are against others opinion. In doing so, I live in a comfortable world where I really don't interact very much to other people. Paul was different. He wanted to unite Jews and gentiles in the people of the Lord and he was not afraid to risk his life to get on it. Paul loved and was loved.
