It is clear from both the prophetic (Jer. 5:7-9) and apostolic (I Cor. 5:1-5) ministries, not to mention the ministry of Christ Himself (Mt. 5:27-32), that ancient cultures had severe problems with sexual immorality. God's obvious concern about this is related to His commandment to the sanctity of marriage. God's Word in this regard needs to be heeded today.
