13 Let us walk properly, as in the day, not in revelry and drunkenness, not in lewdness and lust, not in strife and envy.
not in lewdness [sexual immorality]
Those who fall prey to orgies and drunken bouts are more likely to tumble into bondage to sexual sin.
“Lewdness” or sexual immorality originally referred to a place for lying down, a bed, or a marriage bed. Later it came to mean immoral sexual intercourse.
Sexual immorality is alien to God’s will.
It is amazing how many young evangelicals have developed the rationale that sexual immorality is alright as long as they are not married. There is no biblical rationale for this whatsoever. The Bible is always explicit in saying that sex outside of marriage is sin. See my extensive study on this: http://versebyversecommentary.com/articles/theology-of-sex/
