Acts 16:25-34 - The Conversion Of The Philippian Jailer
25 But about midnight, as Paul and Silas were praying and singing hymns of praise to God, and the prisoners were listening to them, 26 suddenly there was such an earthquake that the jail shook to its foundations; all the doors flew open, and everybody's chains were unfastened. 27 It woke up the jailer, and when he saw that the doors of the jail were open, he drew his sword and was just going to kill himself, supposing that the prisoners had escaped.
28 But Paul shouted out, "Do not do yourself any harm! We are all here!"
29 Then he called for lights and rushed in, and fell trembling at the feet of Paul and Silas. 30 He led them out of the jail and said to them, "Gentlemen, what must I do to be saved?"
31 "Believe in the Lord Jesus," they said, "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 And right then in the night, he took them and washed their wounds, and he and all his household were baptized immediately. 34 Then he took them up to his house and offered them food, and he and all his household were very happy over their new faith in God.
