AThis is an excellent question, and I would like to broaden my response to include the common concern about this issue with regard to eternal security. The text is Matthew 12:30-31
“For this reason I say unto you, Every sin and injurious speaking shall be forgiven to men, but speaking injuriously of the Spirit shall not be forgiven to men. And whosoever shall have spoken a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Spirit, it shall not be forgiven him, neither in this age nor in the coming one.” (Matthew 12:30-31)
One particular evil that has pervaded the Church is clericalism. The clerical principle is a special kind of sin against the Holy Spirit, because it denies the Spirit's place in the Church, and replaces Him with a false system. The clerical principle states that all true ministry flows from the clergy, and any lay preaching is from the Devil. You can see how this evil is of the same character as what the Jewish leaders were guilty of in Matthew 12:30-31. As Israel spoke injuriously against the Spirit in their dispensation, so Christendom has denied the Spirit in our dispensation. The Church has effectively denied the presence and power of the Holy Spirit on earth. Collectively, the Jewish system came into judgment in 70 A.D., and one day the clerical system of Christendom will come into judgment as well, at the middle of Daniel's seventieth week. While we wouldn’t call the clerical principle "blasphemy" against the Holy Spirit, we can see that it is "sin" against the Spirit, and certainly the dispensational counterpart to what Israel was guilty of.1
- There are two aspects to the atonement of Christ. Propitiation is the aspect in which Christ died to perfectly satisfy God. In this aspect He died for the whole WORLD. Substitution is the aspect in which Christ died for ME. In this aspect He only paid for the individual sins of those who would be SAVED.
- Whenever we come to two verses that seem to contradict each other, we need to accept both as true, even if we can't comprehend how they can both coexist. For example; "blasphemy against the Holy Ghost shall not be forgiven unto men" is 100% true and "the blood of Jesus Christ his Son cleanseth us from all sin" is 100% true. What I have started to do is simply accept the Word of God, and then ask him to make it clear to me if it pleases Him. And He usually does.
