Acts 9:20 means that, right after his conversion, Saul began telling people in the synagogues that Jesus is the Christ and the Son of God. The verse shows a changed man at once putting his new faith into public words.
Saul had been a fierce opponent of the believers, and now he stands up in the same kinds of places to say the opposite. The verse is a short summary of what he did once his sight returned and he was baptized.
Immediately in the synagogues he proclaimed the Christ, that he is the Son of God.

What Acts 9:20 Means
The word “immediately” tells you that Saul did not wait for a long period of study or a formal commission. Once he had been filled with the Holy Spirit and had eaten again, he began speaking about Jesus without delay. The sense is of urgency and clarity, a conviction that could not stay quiet.
“In the synagogues” places his preaching in the Jewish meeting houses of Damascus, where he would have been known and where he had once come with authority to arrest believers. The message itself is compact: Jesus is “the Christ,” the promised Messiah of Israel, and “the Son of God,” a title that places him in a unique relationship with the Father. The verse does not describe how Saul argued his case, only that he made it openly and at once. It also does not promise that every listener would believe; the verses that follow show both amazement and opposition.
The Context of Acts 9:20
Acts was written by Luke, the companion of Paul, and it traces how the message of Jesus spread from Jerusalem outward. Luke’s readers were likely Gentile believers who needed to see how the gospel reached beyond the first disciples. This verse sits within the account of Saul’s conversion on the road to Damascus, where Jesus confronts him, and of Ananias’s visit, which restores his sight and brings him into the fellowship of believers.
Just before the verse, Ananias calls Saul “Brother,” a striking welcome for a man who had come to bind the church. Just after it, the surprise of those who knew his past turns into a growing strength in his arguments, and then into a plot against his life. Seen in that setting, the verse marks the first public turn of a life that will soon face danger for the same message.

A Short Prayer From Acts 9:20
Lord, you changed Saul’s heart and gave him the courage to speak your name in the same places where he once opposed it. I ask for that same boldness in my own life. Help me to tell others, plainly and without delay, that Jesus is the Christ and the Son of God. Give me words when I feel unsure, and let my life point people to the one who has rescued me. Amen.
