This is a collection of four previously published articles on blasphemy against the Holy Spirit. They are offered in this special edition to contribute toward three purposes: 1. Restore the correct understanding of the doctrine, which is a straightforward acknowledgment of what Jesus said. 2. Restore the fear of God in the church and in the world, so that fewer people would commit the unpardonable sin and venture pass the point of no return. 3. Restore this weapon to the faithful disciples of Jesus, so that they may combat unbelief and threaten the enemies of the works of the Holy Spirit.
