Acts 16:23-30

Paul and Silas, undaunted, prayed in the middle of the night and sang songs of praise to God, while all the other prisoners listened to their worship. Suddenly, a great earthquake shook the foundations of the prison. All at once every prison door flung open and the chains of all the prisoners came loose.

We’re all still here.” The jailer called for a light. When he saw that they were still in their cells, he rushed in and fell trembling at their feet. Then he led Paul and Silas outside and asked, “What must I do to be saved?”
