Acts of the Apostles 16:31
Believe in the Lord Jesus and you and your household will be saved.
Acts of the Apostles 16:25-34
About midnight, while Paul and Silas were praying and singing hymns to God as the prisoners listened, there was suddenly such a severe earthquake that the foundations of the jail shook; all the doors flew open, and the chains of all were pulled loose. When the jailer woke up and saw the prison doors wide open, he drew [his] sword and was about to kill himself, thinking that the prisoners had escaped. But Paul shouted out in a loud voice, “Do no harm to yourself; we are all here.” He asked for a light and rushed in and, trembling with fear, he fell down before Paul and Silas. Then he brought them out and said, “Sirs, what must I do to be saved?” And they said, “Believe in the Lord Jesus and you and your household will be saved.” So they spoke the word of the Lord to him and to everyone in his house. He took them in at that hour of the night and bathed their wounds; then he and all his family were baptized at once. He brought them up into his house and provided a meal and with his household rejoiced at having come to faith in God.
