Blasphemy against the Spirit will not be forgiven: The Unpardonable Sin is to willfully speak against the work of the Spirit to regenerate our life (Matt. 12:33-37; Mark 12:28-30; Luke 12:10; Heb. 3:12-13; 6:4-6; 10:26-29; 1 John 5:16-17)! This means to reject Jesus’ offer of His saving grace, and refuse His salvation. It can also refer to refusing to repent–a sure sign a person is not saved (John 16:8; Rom. 10:9-10). A Christian whose faith is in Christ has no fear of this, as all of our sins will be forgiven (John 14:26; Acts 7:52; 2 Cor. 3:16-17; Eph. 1:17-18; 1 John 3:9)!
