Matthew 12:30-32 AMPC
He who is not with Me [definitely on My side] is against Me, and he who does not [definitely] gather with Me and for My side scatters.
Therefore I tell you, every sin and blasphemy (every evil, abusive, injurious speaking, or indignity against sacred things) can be forgiven men, but blasphemy against the [Holy] Spirit shall not and cannot be forgiven.
And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Spirit, the Holy One, will not be forgiven, either in this world and age or in the world and age to come.
