Sermons on Speech
In Matthew 12:33-37 Jesus concludes his response to the Pharisees and their accusation against him that he casts out demons by Beelzebub. Christ says that the words a person speaks reveals the contents of their heart. Thus, this blasphemy from the Pharisees reveals the blasphemous character of their hearts. Not only this, but Christ declares that on the last day the true nature of the heart will be revealed by the words a person has spoken.
