Antichrist also means against Christ or in place of Christ .
A substitute for Christ.
Antichrist must come because God's people isreal rejected him first,then rejected Jesus Christ and finally the Holy spirit .
When they blasphemed against Jesus Christ saying he has a devil he told them that such words of blasphemy can be forgiven by the son of Man but not the HOLY SPIRIT.
Matthew 12:31 Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
Anyone or group of persons opening their mouth to blaspheme God or Jesus Christ don't know what they are doing?
The HOLY SPIRIT who is the last worker on earth doesn't rolerate such and there would never be forgiveness for such people in this present world or in the world to come!!!!
The spirit of blasphemy is the spirit of antichrist!!!!
Revelation 13:6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
The antichrist would do this for 42 months blaspheming God and his throne.
Blaspheme is also like saying the work of God is not his own or saying a miracle done is not of God's spirit.
It's like accusing God's spirit and saying the miracle God did is the work of an evil spirit or Satan himself.
There are churches that claim to be of God ,but they speak blasphemy against God,Jesus Christ and his name.
Revelation 2:9 I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan.
Such synagogues are full of darkness.
What they do on the outside is vastly different from what they are on the inside!!!

Revelation 13:1 And I stood upon the sand of the sea, and saw a beast rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy.
Those who say Jesus is a liar and accuse him of doing things with satanic power or through a demon are those who blaspheme

Once they try it with the HOLY SPIRIT,there is no forgiveness in for them.
It's just like attributing a miracle done by A Holyspirt filled man of God to marine, witch,wizard ,familiar spirits or satanic power
By being swift to speak after hearing without ASKING GOD OR CONFIRMING SUCH SOURCE OF POWER,ONE IS HAS COMMITED BLASPHEMY!!!
There is a certain singer who sang "GOD is a woman""
That song is blasphemy against GOD.
Matthew 12:32 And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come
. 12:33 Either make the tree good, and his fruit good; or else make the tree corrupt, and his fruit corrupt: for the tree is known by his fruit.
What this means is that no one that is of Jesus Christ can open his mouth and begin to curse Jesus Christ or speak lies and hard speeches against Jesus Christ.
One of a good tree cannot bring forth corrut fruit unless the tree is corrupt.
It cannot bring forth good fruit either.
We must be wary of this character of the antichrist,he cannot totally manifest as good,on the long run he would become evil.
When antichrist would come,he would first come to make PEACE!!!!!
Then when all superpower nations and others surrender their weapons and a peace treaty is signed between Isreal and the Arab league of nations ,then The Antichrist would break the peace treaty and watch when these nations attack Isreal!!!!
Does Jesus Christ change? No!!!!
Does the antichrist change Yes!!!!!
He would change and became a terror to many.
Then his true characters would be unleashed during the second 3 and a half years.
It is then the eyes of the Jews would be opened and they would see they have been deceived and now reject the Beast and become ready to pay with their blood!!!
Revelation 17:3 So he carried me away in the spirit into the wilderness: and I saw a woman sit upon a scarlet coloured beast, full of names of blasphemy, having seven heads and ten horns.

God bless you real good in the mighty name of Jesus Christ Amen
