29 Then he called for a light, ran in, and fell down trembling before Paul and Silas.
30 And he brought them out and said, “Sirs, what must I do to be saved?”
31 So they said, “Believe on the Lord Jesus Christ, and you will be saved, you and your household.”
32 Then they spoke the word of the Lord to him and to all who were in his house.
33 And he took them the same hour of the night and washed their stripes. And immediately he and all his family were baptized.
34 Now when he had brought them into his house, he set food before them; and he rejoiced, having believed in God with all his household.

When “the people” had asked John the Baptist: “What shall we do then?” he had insisted upon the fruits of repentance and of the kingdom (Luke 3:9-11). When a lawyer had asked our Lord: “What shall I do to inherit eternal life?” the Lord had asked him: “What is written in the law?” and had instructed him: “This do, and thou shalt live” (Luke 10:25-28). When Peter’s convicted hearers at Pentecost had asked: “What shall we do?” Peter had directed them to “repent and be baptized … for the remission of sins” (Acts 2:37-38). But now, under Paul, the clear, pointed messages is: “Believe on the Lord Jesus Christ, and thou shalt be saved.” — Stam, page 62
