Matthew 12:31-32

31 God is able to forgive all the wrong things that people do. He also forgives the bad things that people say against other people. But God will never forgive people who say bad things against the Holy Spirit. 32 God will forgive people who say bad things against me, the Son of Man. But God will never forgive people who say bad things against the Holy Spirit. He will not forgive them now or ever.’
