Mark 3:29 Meaning and Commentary

Mark 3:29

But he that shall blaspheme against the Holy Ghost
Against his person, and the works performed by him, by ascribing them to diabolical power and influence, as the Scribes did,

hath never forgiveness:
there is no pardon provided in the covenant of grace, nor obtained by the blood of Christ for such persons, or ever applied to them by the Spirit;

but is in danger of eternal damnation.
The Vulgate Latin reads it, and so it is read in an ancient copy of Beza's, guilty of an eternal sin; a sin which can never be blotted out, and will never be forgiven, but will be punished with everlasting destruction; (See Gill on Matthew 12:32).

28 “I tell you the truth, all sin and blasphemy can be forgiven,

29 but anyone who blasphemes the Holy Spirit will never be forgiven. This is a sin with eternal consequences.”

30 He told them this because they were saying, “He’s possessed by an evil spirit.”

31 Then Jesus’ mother and brothers came to see him. They stood outside and sent word for him to come out and talk with them.
