What does Acts 9:26 mean?
Saul is a Jesus-follower. Before he was a Jesus-follower, he was the leading persecutor of the church (Acts 8:1–3; 9:1–2). He imprisoned and beat Jesus-followers, tried to get them to blaspheme, and voted for their execution if they didn't (Acts 22:19; 26:10–11). But on his way to Damascus to hunt down more Jesus-followers, Saul met Jesus. He accepted that he was completely wrong, and immediately started preaching in the synagogues that Jesus is the Jewish Messiah. Now, he is ready to return to Jerusalem and meet the leaders of the faith he has spent over three years learning about (Acts 9:1–25; Galatians 1:15–18). In time, he will go by his Greek name, Paul, and become the greatest missionary of the early church (Acts 13:9).Saul quickly learns that three years is not a very long time, when one's reputation is so strong. The church leaders know very well who he is. They haven't heard about him for years, but with his return their fear is renewed.
It's very likely this event stays with Saul. Years later, he will write to the church in Corinth about a sinful but unrepentant Jesus-follower, telling them the church needs to remove him from their fellowship (1 Corinthians 5:1–5). Later, it appears the man repents, but the church isn't ready to forgive. Saul will tell them:
Acts 9:26–31 draws a curtain on the persecution of the church at the hands of the Pharisee-trained Saul. The young man who ''[breathed] threats and murder against the disciples of the Lord'' (Acts 9:1) has chosen to follow Jesus instead. He has spent several years learning more about how Jesus is the Jewish Messiah and sharing his new-found understanding at synagogues in Damascus. Now, he returns to Jerusalem—not to the Sanhedrin who gave him his orders, but to the leaders of the church he once tried to destroy.
Acts 9 sets the stage for the spread of the gospel to the Gentiles. Saul continues the persecution of the church by traveling to Damascus to arrest Jesus-followers. Before he reaches the city, Jesus confronts him. Saul realizes Jesus is the Messiah and immediately starts spreading the news, first in Damascus and later in Jerusalem. Meanwhile, Peter travels to modern-day Tel Aviv to heal a paralyzed man and bring a dead woman back to life. The miracles aren't unusual, but the story leaves him in Joppa, poised to take the next step in Jesus' mandate to be His witness (Acts 1:8).
