Practice what you preach! Live what you want others to learn. After being knocked off his horse, St. Paul spent eight or possibly 12 years of prayer and formation before he went out to speak about Gods Word with real authority, strength, and conviction. His words were more than just words, because he lived and witnessed by his life the authenticity of Jesus own words and example. To truly learn this lesson one must change their opinions, way of doing things, behaviors, and even likes and dislikes that are not a reflection of Jesus. Live and learn these messages, before teaching them to others. Our Lady will help you.
