Believe on the Lord Jesus Christ, A Study of Acts 16.

Acts 16:28-31 But Paul called with a loud voice, saying, “Do yourself no harm, for we are all here.” Then he called for a light, ran in, and fell down trembling before Paul and Silas. And he brought them out and said, “Sirs, what must I do to be saved?” So they said, “Believe on the Lord Jesus Christ, and you will be saved, you and your household.”
