“You, then, who teach others, do you not teach yourself? You who preach against stealing, do you steal? You who say that people should not commit adultery, do you commit adultery? You who abhor idols, do you rob temples? You who brag about the law, do you dishonor God by breaking the law?”
Romans 2:21-23 (NIV)
In order to teach, a teacher must learn. Not just to say “this is what the books says”, but understand it. It is the same with God’s Word. We cannot teach people to obey God’s Word and be disobedient ourselves. Are you a teacher? Are you obeying what you teach?
