We’re forgiven of all our sins, including speaking against Jesus.

But, there’s NO forgiveness for speaking against the Holy Ghost. In this life or the life to come.

Matthew 12:31-32 (KJV) – wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
