Matthew 12:32-36

32Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come. 33“Make a tree good and its fruit will be good, or make a tree bad and its fruit will be bad, for a tree is recognized by its fruit. 34You brood of vipers, how can you who are evil say anything good? For the mouth speaks what the heart is full of. 35A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him. 36But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken.
