For this is the will of God: your sanctification, that you abstain from sexual immorality,
That ye should abstain from fornication - A vice which was freely indulged among the pagan, and to which, from that fact, and from their own former habits, they were particularly exposed. On the fact that they were thus exposed, and on the reasons for these solemn commands on the subject, see the Acts 15:20 note, and 1 Corinthians 6:18 note.
