Read: Ecclesiastes 12:14
There are people who pretend to live a life of holiness, but they do not have a clean heart. Jesus condemned the Pharisees and religious leaders for not practising what they preached. Jesus openly addressed them as hypocrites and blind guides (Matt. 23). God will bring every deed into judgement, including every hidden thing, whether good or evil (Eccl. 12:14). Our God is holy and He expects His people to be true to Him and obey His commandments faithfully. There are several incidents in the Bible where God exposed the sins of people who disobeyed Him.
