Matthew 12:30-32
Matthew 12: 30 to 32
30 He who is not with Me is against Me, and he who does not gather with Me scatters.
31 Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven.
32 Whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the one to come.
