Acts 18:8

8. Although he left the synagogue in apparent discomfiture, he was not without fruits of his labors there. (8) " But Crispus, the chief ruler of the synagogue, believed on the Lord, with all his house; and many of the Corinthians, hearing, believed and were immersed. " It was very seldom that men of high position in the Jewish synagogues were induced to obey the gospel. It is greatly to the credit of Crispus, therefore, that he was among the first in Corinth to take this position, and this, too, at the moment when the opposition and blasphemy of the other Jews were most intense. He must have been a man of great independence of spirit and goodness of heart-the right kind of a man to form the nucleus for a congregation of disciples.

The conversion of these Corinthians is not detailed so fully as that of the eunuch, of Saul, or of Cornelius, yet enough is said to show that it was essentially the same process. "Many of the Corinthians, hearing, believed, and were immersed." They heard what Paul preached, "that Jesus is the Christ." This, then, is what they believed. That they repented of their sins is implied in the fact that they turned to the Lord by being immersed. To hear the gospel preached, to believe that Jesus is the Christ, and to be immersed, was the entire process of their conversion, briefly expressed.
