Acts 16:31

"And they said, Believe on the Lord Jesus, and thou shalt be saved, thou and thy house"Believe on the Lord Jesus" Unfortunately many people stop right here and assume that one is saved at the moment they believe that Jesus is the Son of God, such as the idea of salvation by faith alone. But the next verse reveals that the jailer needs to hear the gospel, before he can believe (Romans 10:17 "Faith comes by hearing"). In addition, the statement believe on the Lord Jesus, does not precisely tell us what we must believe about Jesus. McGarvey notes, "Those who catch at these words of Paul to the jailer, and draw the conclusion that salvation is by faith alone, leave the jail too soon. They should remain till they hear all---till they hear Paul tell the man to repent and be baptized, till the design of baptism is explained to him, till he is baptized, till he is found rejoicing greatly immediately after his baptism" (p. 103). "Thou and thy house" This salvation is also available to all the members of his household who are able and willing to believe.
