Note 2 at Acts 16:30: This jailer's question was very similar to the rich young ruler's question to Jesus (see notes 1 and 2 at Mt. 19:16 and 17, pp. 387- 388), and 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 asking what the Lord required of him.

The same humble attitude that this jailer expressed is an essential requirement for salvation. No one can put their total faith in Jesus as Savior until they have no faith in themselves and their own good works.
