THE 4 BIBLE PASSAGES:
1 John 2:18-19 "Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have arisen; from this we know that it is the last hour. They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, in order that it might be shown that they all are not of us."
1 John 2:22-23 "Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son. Whoever denies the Son does not have the Father; the one who confesses the Son has the Father also."
1 John 4:2-3 "By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; and every spirit that does not confess Jesus is not from God; and this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world."
2 John 1:7 "For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist."
From the Bible we can clearly see 3 things. First, the "antichrist" is defined as anyone who doesn't believe Jesus is the divine son of God. Second, "antichrists" appear to actively teach against Christ. Third, there were many "antichrists" in the world when John wrote the book. This directly contradicts the teaching of modern speculationists who say that one antichrist will arise at some still future time.
WRONG!!! There are antichrists, but there is one we are warned about who will come in the last days.
The antichrist beast referred to in the last times is described in Daniel 7.
Dan 7:23 Thus he said, The fourth beast shall be the fourth kingdom upon earth, which shall be diverse from all kingdoms, and shall devour the whole earth, and shall tread it down, and break it in pieces.
Dan 7:24 And the ten horns out of this kingdom are ten kings that shall arise: and another shall rise after them; and he shall be diverse from the first, and he shall subdue three kings.
Dan 7:25 And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
Dan 7:26 But the judgment shall sit, and they shall take away his dominion, to consume and to destroy it unto the end.
Jesus spoke of this antichrist beast
Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
Mat 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand:)
Mat 24:16 Then let them which be in Judaea flee into the mountains:
Rev 13:4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
Rev 13:5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
Rev 13:6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
Rev 13:7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
Rev 13:8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
Rev 13:9 If any man have an ear, let him hear.
This is the antichrist Beast we refer to as described in the Bible.
