Acts 16:25-34 - The Conversion Of The Philippian Jailer
25 But about midnight, while Paul and Silas were praying and singing hymns of praise to God, and the prisoners were listening to them, 26 suddenly there was an earthquake so great that it shook the very foundations of the jail, the doors all flew open, and every prisoner's chains were unfastened. 27 When the jailer awoke and saw that the jail doors were open, he drew his sword and was on the point of killing himself, because he thought that the prisoners had escaped.
28 But Paul at once shouted out to him, "Do yourself no harm, for we are all here!"
29 Then the jailer called for lights and rushed in and fell trembling at the feet of Paul and Silas. 30 After leading them out of the jail, he said, "Sirs, what must I do to be saved?"
31 They answered, "Believe on the Lord Jesus, and you and your household will be saved." 32 Then they told God's message to him and to all the members of his household. 33 Even at that time of the night he took them and washed their wounds, and he and all the members of his household at once were baptized. 34 Then he took them up to his house and gave them food, and he and all the members of his household were happy in their faith in God.
