Horatius Bonar considers the subjects of blasphemy against the Holy Spirit referred to in Mark 3:28-30, and the "sin unto death" in 1 John 5:16,17. Carefully considering these things according to the Scriptures, Bonar makes the distinction between the unforgiven blasphemies against the Holy Spirit found in the reprobate's unbelief, and the forgiven sins of the believer which, though they may lead to the divine chastisement of death, are forgiven in Christ.
