“Mark 3:29... The Bible leaves “blaphemy against the Holy Spirit” undefined.”
Also note true, although this is not understood by most people. All you needed to do was read Mark 3:30 to find out what it means.
Matthew 12:31 states that the only unforgivable sin is that of blaspheming the Holy Spirit. Mark 3:29 also states the same thing, but there is clarification in Mark 3:30: “He said this because they were saying, ‘He has an impure spirit.’” So the sin of the Pharisees was that of accusing Jesus of being Satan. They were literally exchanging Truth for a lie (Romans 1:25).
“So the sin of the Pharisees was that of accusing Jesus of being Satan.”
Ah, I think you’re right there, but this is completely different than the man-made definition that was being spouted.
