Matthew 12:28-31

But if I cast out demons by the Spirit of God, then the kingdom of God has come upon you. Or how can anyone enter the strong man’s house and carry off his property, unless he first binds the strong man? And then he will plunder his house. He who is not with Me is against Me; and he who does not gather with Me scatters. “Therefore I say to you, any sin and blasphemy shall be forgiven people, but blasphemy against the Spirit shall not be forgiven.
