1 Peter 4:3

Peter’s readers had already spent too much time living for self in typically unsaved Gentile practices. Note the prominence of sexual and alcohol related activities here (as in Romans 13:13-14; Galatians 5:19-21). This verse along with others (e.g., 1 Peter 1:14; 1 Peter 2:10) suggests that Peter was writing to a predominantly Gentile audience.
