SEV Biblia, Chapter 3:28
De cierto os digo que todos los pecados sern perdonados a los hijos de los hombres, y las blasfemias cualesquiera con que blasfemaren;
John Gill's Bible Commentary
Ver. 28. Verily I say unto you , etc..] The Scribes and Pharisees, who had not only blasphemed him, but the Spirit of God also: all sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme ; God; or the Son of God, angels, and men, and that through the blood of Christ, and when brought to a sense of the evil of them; for though pardon is procured before, it is not applied till then; (see Gill on Matthew 12:31).
Matthew Henry Commentary
Verses 22-30 - It was plain that the doctrine of Christ had a direct tendency to brea the devil's power; and it was as plain, that casting of him out of the bodies of people, confirmed that doctrine; therefore Satan could no support such a design. Christ gave an awful warning against speakin such dangerous words. It is true the gospel promises, because Chris has purchased, forgiveness for the greatest sins and sinners; but by this sin, they would oppose the gifts of the Holy Ghost after Christ' ascension. Such is the enmity of the heart, that unconverted me pretend believers are doing Satan's work, when sinners are brought to repentance and newness of life.
