7 Then Paul left the synagogue and went next door to the house of Titius Justus, a worshiper of God. 8 Crispus, the synagogue leader, and his entire household believed in the Lord; and many of the Corinthians who heard Paul believed and were baptized. 9 One night the Lord spoke to Paul in a vision: "Do not be afraid; keep on speaking, do not be silent. 10 For I am with you, and no one is going to attack and harm you, because I have many people in this city."

Commentary on Acts 18:7-11

(Read Acts 18:7-11)

The Lord knows those that are his, yea, and those that shall be his; for it is by his work upon them that they become his. Let us not despair concerning any place, when even in wicked Corinth Christ had much people. He will gather in his chosen flock from the places where they are scattered Thus encouraged, the apostle continued at Corinth, and a numerous and flourishing church grew up.
