Matthew 12:29-31

29 Or how can a person go into a strong man’s house and carry off his goods (the entire equipment of his house) without first binding the strong man? Then indeed he may plunder his house.

30 He who is not with Me [definitely [12]on My side] is against Me, and he who does not [definitely] gather with Me and for [13]My side scatters.

31 Therefore I tell you, every sin and blasphemy (every evil, abusive, [14]injurious speaking, or indignity against sacred things) can be forgiven men, but blasphemy against the [Holy] Spirit shall not and [15]cannot be forgiven.
