Please tell us what the context is for Mark 3:29? Then maybe we can know the truth? IOW don't tell us it is out of context, but tell us what the context is so we can mend our ways, if you can.
I will gladly show the context again to help people understand.
We must remember that all three synoptics give commentary of this event. Matt. 12: 22-32, Mk. 3:22-30, Luke 11:14-20.
Let us set the biblical scene.
Jesus had come to present the kingdom to Israel and showed HImself to be the long awaited Messiah! We know John was His forerunner and when Jesus sent out the disciples, they were to only go to Jews and announce th ekingdom of heaven had come.
Jesus performed many public miracles to show Himself the Messiah, but there were three that stand out in particular. The reason they stood out is that it had been taught in jewish cirlces that these 3 miracles could only be done when Messiah came. These three miracles were: 1: the healing of a man born blind, 2: The healing of Jewish Lepers ( never had been done prior to Jesus) and 3. the casting out of a demon from a deaf dumb man. Jews could cast demons out, but they had to establish communication with the demon, learn its name and then using its name, cast it out. By the exzorcism in the gospel passages, Jesus had already healed the lepers, gave sight to teh man born blind (both these are well commented on in the scriptures) and now He performs the third and final messianic miracle- the exorcism of a demon from a deaf and dumb man.
Remember we muyst look at all three passages to get the full picture of what took place at this event. but let us look at Matt. 12: 22-23
22 Then was brought unto him one possessed with a devil, blind, and dumb: and he healed him, insomuch that the blind and dumb both spake and saw.
23 And all the people were amazed, and said, Is not this the son of David?
The people asked the pharisees a rhetorical question here. They were saying this is the Messiah isn't it? (Son of David is a Messianic title). The reason why they said this is because they were taught all their lives that only Messiah could do this miracle. So the pharisees were forced to give an answer- Yes He is or no He isn't Messiah, but give a reason why He is not Messiah! We know their choice.
24 But when the Pharisees heard it, they said, This fellow doth not cast out devils, but by Beelzebub the prince of the devils.
This is the blasphemy of the Holy Spirit and Judgment was set against that generation.
1. the kingdom was revoked from that generation to be given to afuture generation of Israel.
2. Physical judgment was set and defined in Luke 21:20-24
20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
21 Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.
22 For these be the days of vengeance, that all things which are written may be fulfilled.
23 But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people.
24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
this had been previously prophesied (though not in such detail) and fulfilled in the 66-70 Ad siege and destruction of Jerusalem.
Also the entire nature of Jesus ministry changed. No longer did Jesus send out the disciples saying "Repent for the kingdom of heaven is at hand" for th ekingdom was revoked and postponed.
He taught the masses only in parables to hide the truth from them.
Matt. 13:10-15:
10 And the disciples came, and said unto him, Why speakest thou unto them in parables?
11 He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
12 For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:
15 For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
Also th eonly public miracle He did was the sign of Jonah to the Jews-resurrection. He did it twice while on earth (Lazarus and Himself) and will do it one more time to Israel with the two witnesses. All miracles after this point were personal and on the basis of faith.
Also He now went and prepared the disciples to build the church. It was also at this point that the pharisees had gone from inquiry, to investigation (that is why they were there- investigating Jesus) to accusing to later plotting to condemn Him.
So why is this blasphemy only capable by the nation of Israel when Jesus walked on the earth?
1. He performed a miracle that was taught only Messiah could do.
2. The Pharisees accused Jesus of being demon possessed to perform the Messianic miracle. (The pharisees knew He was Messiah at this point but did not want this kind of Messiah).
3. Finally the judgments Jesus pronounced to that genersation because of the national rejection of Jesus (individuals believed but the leaders rejected)
Matt. 12: 41-45:
41 The men of Nineveh shall rise in judgment with this generation, and shall condemn it: because they repented at the preaching of Jonas; and, behold, a greater than Jonas is here.
42 The queen of the south shall rise up in the judgment with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here.
43 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none.
44 Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished.
45 Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
So the blasphemy of the Spirit ( or railing agains tthe spirit) could only be done when Jesus performed miracles and someone accuses Jesus of being demon possessed.
there is more and more context that could be given, but I hope this helps.
