Luke 11:15

11:15 But some of them said, “By the power of Beelzebul, the ruler of demons, he casts out demons.”

Matthew 12:31-34

12:31 For this reason I tell you, people will be forgiven for every sin and blasphemy, but the blasphemy against the Spirit will not be forgiven. 12:32 Whoever speaks a word against the Son of Man will be forgiven. But whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.

Trees and Their Fruit

12:33 “Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is known by its fruit. 12:34 Offspring of vipers! How are you able to say anything good, since you are evil? For the mouth speaks from what fills the heart.

James 3:5-8

3:5 So too the tongue is a small part of the body, yet it has great pretensions. Think how small a flame sets a huge forest ablaze. 3:6 And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence – and is set on fire by hell.

3:7 For every kind of animal, bird, reptile, and sea creature is subdued and has been subdued by humankind. 3:8 But no human being can subdue the tongue; it is a restless evil, full of deadly poison.
