“And he left there and went to the house of a man named Titius Justus, a worshiper of God. His house was next door to the synagogue” (v7). Paul could not have preached the gospel without Priscilla and Aquila, tent-makers and teachers, who hosted him in Corinth and in Ephesus taught the great preacher Apollos (v26). Silas and Timothy arrived to support Paul (v5), Titius Justus opened his home, and Crispus, the believing synagogue leader, must have added his influence (v8).
“For I have many in this city who are My people” (v10). When God’s people work in unity for His purposes, the good news about Jesus spreads and the church grows.
