Matthew 12:28-34

But if I am casting out demons by the Spirit of God, then the Kingdom of God has arrived among you. For who is powerful enough to enter the house of a strong man and plunder his goods? Only someone even stronger—someone who could tie him up and then plunder his house. “Anyone who isn’t with me opposes me, and anyone who isn’t working with me is actually working against me. “So I tell you, every sin and blasphemy can be forgiven—except blasphemy against the Holy Spirit, which will never be forgiven. Anyone who speaks against the Son of Man can be forgiven, but anyone who speaks against the Holy Spirit will never be forgiven, either in this world or in the world to come. “A tree is identified by its fruit. If a tree is good, its fruit will be good. If a tree is bad, its fruit will be bad. You brood of snakes! How could evil men like you speak what is good and right? For whatever is in your heart determines what you say.
