What does the Bible say about blasphemy against the holy ghost?

Bible Topic · WEB

The Bible warns that blasphemy against the Holy Spirit is a grave, willful rejection of God’s clear saving work, especially by calling the Spirit’s work evil, and it leaves no forgiveness because it refuses the only source of forgiveness. In Matthew 12:31-32 and Mark 3:28-30, Jesus spoke this warning when religious leaders knowingly attributed His Spirit-empowered works to Satan. Luke 12:10 likewise distinguishes careless words about the Son of Man from hardened opposition to the Spirit. This is not an accidental statement, a season of doubt, or a sin that a repentant believer cannot bring to Christ. Those who fear they have committed it should be encouraged to seek the Lord, trusting that all who truly repent and believe are received by His grace.
