Now why would Jesus give this statement about blasphemy of the Holy Spirit? When Jesus came up from His baptism, John proclaimed, "When I saw the Holy Spirit come down and remain on Him, I saw and bore record that this IS the Son of God!" Jesus did not do these miracles solely by himself. So their accusation was against the Holy Spirit. I will not make any comments whether anyone else could be subject to Jesus' statement, especially the scoffers of today.
I want to make a statement about a kingdom divided. Jesus statement in John 17:21, That they all may be "one"--that the world may know that you have sent me. What a disservice to the world that God's people are so divided. The people's talk affected Jesus' mother and brothers. I think Mary should have known better. It seems they wanted to speak to Him to ease off a little, but He countered with a question: Who is my mother and my brothers? Then it was those who entered a relationship with Him by hearing Him. Now it is the same. I began my relationship with Him in May 1956, fifty eight years ago. I heard Him then and am still hearing Him today.
