A person who has a deceitful and lying heart tends to hide his shortcomings or make it sound trivial and tends to exaggerate something advantageous to him. In his conscience he may think he does not lie. And he does not admit it even when others point it out. However, we should speak in an objective way so that listeners can be fully aware of a situation and the people involved without bias. Also, we can be changed only when we admit our shortcomings that others point out.
