Acts 15:35 provides a snapshot of Paul and Barnabas's continued ministry in Antioch after a significant event – the Jerusalem Council. Let's break down what the verse implies:

"But Paul and Barnabas stayed in Antioch...": This highlights their commitment to the church in Antioch. They didn't immediately move on to new territories after the Jerusalem Council (where it was decided that Gentile converts didn't need to follow Jewish law). This signifies the importance of ongoing discipleship and nurturing existing believers.

"...teaching and preaching the word of the Lord...": This is the core of their ministry.

Teaching suggests in-depth instruction, explaining the Scriptures, clarifying doctrine, and providing a solid foundation for believers to understand their faith.
Preaching often implies a more public proclamation of the Gospel, calling people to repentance and faith in Jesus Christ.

Both teaching and preaching are essential for spiritual growth and evangelism.

"...with many others also.": This is important for several reasons:

It emphasizes that Paul and Barnabas weren't operating in isolation. They were part of a larger team.
It suggests that the church in Antioch was growing and developing its own leadership.
It points to the collaborative nature of ministry in the early church, where many individuals shared the responsibility of spreading the Gospel.

In summary, Acts 15:35 portrays Paul and Barnabas' dedication to establishing and strengthening the church in Antioch. They did this through both thorough instruction and public proclamation of the Gospel, working alongside other believers who shared in this mission. The verse underscores the importance of consistent discipleship, collaborative ministry, and the ongoing spread of the Gospel message.

The verse also sets the stage for Paul and Barnabas's eventual separation (later in Acts 15), as they prepare for further missionary journeys. But for the time being, their focus is on nurturing the church where they were based.
