Matthew 12:31-33

Darby Translation

³¹ For this reason I say unto you, Every sin and injurious speaking shall be forgiven to men, but speaking injuriously of the Spirit shall not be forgiven to men.

³² And whosoever shall have spoken a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Spirit, it shall not be forgiven him, neither in this age nor in the coming [one].

³³ Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt. For from the fruit the tree is known.
