“Therefore I tell you, every sin and blasphemy will be forgiven people, but the blasphemy against the Spirit will not be forgiven. And whoever speaks a word against the Son of Man will be forgiven, but whoever speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.” Matthew 12:31-32
Jesus healed and cast demons out of a man by the power of the Holy Spirit. God performed this healing by his Holy Spirit through Jesus to show that Jesus was the promised Messiah (Christ) who had come to defeat Satan, inaugurate God’s kingdom on earth, and be the Savior of the world. The Jewish leaders (Pharisees) did not believe that this miracle was evidence from God that Jesus was the Savior of the world. They believed that this miracle was evidence from Satan that Jesus was possessed by the devil.
