There is something interesting about truth and that is it is not understood properly when it is not practiced. This reality becomes especially obvious when someone teaches a topic, they do not have experiential knowledge of. Being a leader assumes the person knows where they are going. Being a teacher assumes that they have an intimate knowledge of the topic they are teaching. Are the doctor’s solutions working for him and his family? How are the pastor’s teachings working out for him and those who follow his teachings? Are the business practices that that guru teaches working for him? True knowledge is deeper than acquiring information.
Luke 6:39 And he spake a parable unto them, Can the blind lead the blind? shall they not both fall into the ditch?
