Mark 3:29

3:29 blasphemes against the Holy Spirit. For various forms of blasphemy, see 2:7; Ex. 22:28; Lev. 24:10–16; Ezek. 35:12, 13; John 10:33–36; Acts 6:11. The unforgivable blasphemy specified here is the act of deliberately associating the power and the work of Jesus, who is full of the Holy Spirit, with the work of Satan. This is to equate supreme spiritual good with supreme spiritual evil, hardening one’s heart in a way that makes repentance, and therefore forgiveness, impossible. See theological note “The Unpardonable Sin.”
