A pretty good, short overview of the question from the Scriptures. Open your mind to God, and go deaf to the culture and your own deceitful heart!
My only caveat is that the speaker uses a Bible version that translates the Greek word porneia as “sexual immorality” and not “fornication.” I prefer the latter, since the former is too vague. But other than that, the content is spot-on.
