What IS blasphemy against the Holy Spirit?
I know the answer I would give, but I’m curious how others would respond.
Looking at Mark 3:29, “... but whoever blasphemes against the Holy Spirit never has forgiveness ...”, “whoever” is clearly not a believer, for “In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace.” (Ephesians 1:7, NASB)
