Some Things Wrong With Mixed Bathing
H. L. Bruce
Mixed bathing is wrong because it produces lust. Paul told Titus that Christians are to deny "ungodliness and worldly lust" (Tit. 2:12). A man who looks upon a woman to lust after her is guilty of adultery in his heart (See Matt. 5:28). Mixed bathing is wrong because men and women who are not married to each other have no right to be together dressed (undressed) like that. To cause one to stumble is sin (Rom. 14:21).
When Christians indulge in mixed bathing their influence says that they disregard the teachings of God's Word (See Matt 5:16). Christians should abstain from mixed bathing to obey God and go to heaven (Rev. 22:14). If you have been indulging in mixed bathing, you should repent and quit it. If you have been allowing your children to do so, you should rather teach them to respect God's will.
