Matthew 12:30-37

He who is not with Me [once and for all on My side] is against Me; and he who does not [unequivocally] gather with Me scatters. [Luke 9:50; 11:23] “Therefore I say to you, every sin and blasphemy [every evil, abusive, injurious speaking, or indignity against sacred things] will be forgiven people, but blasphemy against the [Holy]Spirit will not be forgiven. Whoever speaks a word against the Son of Man will be forgiven; but whoever speaks against the Holy Spirit [by attributing the miracles done by Me to Satan] will not be forgiven, either in this age or in the age to come. [Mark 3:29; Luke 12:10] “Either make the tree good and its fruit good, or make the tree bad and its fruit bad; for the tree is recognized and judged by its fruit. You brood of vipers, how can you speak good things when you are evil? For the mouth speaks out of that which fills the heart. The good man, from his [inner]good treasure, brings out good things; and the evil man, from his [inner]evil treasure, brings out evil things. But I tell you, on the day of judgment people will have to give an accounting for every careless or useless word they speak. For by your words [reflecting your spiritual condition] you will be justified and acquitted of the guilt of sin; and by your words [rejecting Me] you will be condemned and sentenced.”
