Obviously, blasphemy against the Spirit has nothing to do with cussing; it has to do with mocking the works of the Holy Spirit, with the intent on keeping others from wholeheartedly following Christ. Jesus alerted the Pharisees to the possibility of them committing this unpardonable sin when they accused Him of driving out demons by the power of Beelzebub, the prince of demons. (see Matthew 12:22-32 and Mark 3:22-30). Did Jesus take this slander personally? No. He, in fact, steers their criticism away from Himself and directs their criticism toward the Holy Spirit. He indicates that their judgment, though it seemed targeted against Himself, was really aimed at the Holy Spirit. "I drive out demons by the Spirit of God," Jesus proclaimed to His accusers. To criticize a miracle from Jesus was equivalent to criticizing a miracle of the Holy Spirit. His power came from the Spirit.
