Matthew 12:29-32

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. Whoever speaks a word against the Son of Man, it shall be forgiven him; but whoever speaks against the Holy Spirit, it shall not be forgiven him, either in this age or in the age to come.
