The harder they preach against, and unmercifully condemns you for committing sexual immorality and adultery, watch out, because they are often the ones who are doing it themselves! History has showed that more than once. They are like the religious leaders in the Bible who teach others that it’s wrong to commit adultery, yet they commit adultery themselves (see Romans 2:20). They are like the ones who went to spy on a woman having sex with another man, so they could catch her in the act of committing adultery and having her stoned to death as the law required in the Old Testament. But Jesus challenged these hypocritical religious teachers by saying to them: “He who is without sin among you, let him throw a stone at her first.” None of them could throw a stone at the woman, because Jesus exposed them as being sinners themselves (see John 8:1-11). Yes, their evil intentions were exposed when the light shined on them, for the light makes everything visible (see Ephesians 5:13-14).
It’s exactly the same with many of those hypocritical preachers who pridefully – and without compassion – condemn others for committing adultery and involving themselves in God forbidden sexual acts, while they themselves are the ones who secretly download all sorts of perverted sexual images from porn websites on their computers, and have secret emotional and sexual affairs with other men, women, and even underage children. It is indeed a true saying that “pride goes before destruction,and haughtiness before a fall.” Proverbs 16:18 NLT
