Now the son of Paul’s sister heard of their ambush, so he went and entered the barracks and told Paul.
Acts 23:16 (ESV)
Is Paul's sister in Acts 23:16 his biological sister?
If so,then, the significance of this record links with Acts 16:31 ("Believe on the Lord Jesus and you will be saved, you and your household") since it has shown us that Paul had his relatives saved just as he was.
