Note 3 at Acts 16:31: Paul and Silas' answer to the jailer about what he must do to be saved is exactly the same as Jesus' answer to the Jews in Jn. 6:29. Faith in what Jesus did for us is the only requirement and the only thing that we can do to produce salvation (see notes 2-3 at Lk. 11:42 and 44, p. 323).

Paul and Silas did not say that this man had to confess his sins. That is a common instruction given to people who ask this question today and it can be appropriate if by confessing their sins an individual is simply admitting he's guilty and needs a Savior. But the belief that an individual has to confess each individual sin in order to be saved is unscriptural. What would happen if we forgot one? Would it not be forgiven? We don't confess our sins but rather we confess our faith in the sacrifice of Jesus as the perfect payment for our sins (see note 7 at Mk. 1:5, p. 69).

Note 4 at Acts 16:31: Many people have mistakenly used this scripture as a verse that promises them that their loved ones will be saved as they stand in faith believing for their salvation. That is not what this verse means. We can not get anyone born-again on our faith even if they are near of kin. Paul and Silas were simply stating that this jailer could be born-again by believing on the Lord Jesus Christ and the same thing would work for his family if they would believe.

This is not to say that there are no scriptures to encourage us to believe for the salvation of our family members and friends. There are (see note 1 at Mt. 9:38, p. 218). This is just not one of them.
