Note 2 at Ac 16:30: This jailer's question was very similar to the rich young ruler's question to Jesus (see note 1 at Mt 19:16 and note 2 at Mt 19:17), yet what they were saying was completely different. The rich young ruler was putting the emphasis on "what good thing shall I do," while this jailer was totally repentant and simply asked what the Lord required of him.

The same humble attitude that this jailer expressed is an essential requirement for salvation. People cannot put their total faith in Jesus as Savior until they have no faith in themselves and their own good works.
