Acts 16:29-34

Then he called for a light, ran in, and fell down trembling before Paul and Silas. 30 And he brought them out and said, “Sirs, what must I do to be saved?”

31 So they said, “Believe on the Lord Jesus Christ, and you will be saved, you and your household.” 32 Then they spoke the word of the Lord to him and to all who were in his house. 33 And he took them the same hour of the night and washed their stripes. And immediately he and all his family were baptized. 34 Now when he had brought them into his house, he set food before them; and he rejoiced, having believed in God with all his household.

1John 3:22-23

And whatever we ask we receive from Him, because we keep His commandments and do those things that are pleasing in His sight. 23 And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment.
