Any person who denies that Jesus Christ is the Son of God is an Antichrist.
I John 2:22-23
22 “Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.”
23 “Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also.”
I John 4:3: “And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.”
There will be many antichrists saying Jesus is not the Son of God, and there will be two prominent antichrists.
These antichrists are the Beast and the False Prophet.
The Beast and the False Profit are Satan’s counterfeits of God and Jesus. The Beast will be the Son of Perdition that sets himself up as God here on earth and the False Profit will be the Pope of the Catholic Church.
In order to rule the world, Satan must unite all religions: the Jews, Muslims, Hindus, Buddhists, Catholics, and all other religions.
All religions have a god. Satan will convince the world religions that their god and the Christian God are all the same gods. These religions would worship God, but none of them would worship Jesus Christ as the Son of God. In order to unite the religions of the world, Satan must do away with the fact that Jesus Christ is the Son of God.
The Antichrists will teach that Jesus Christ is not the Son of God which is the lie of II Thessalonians 2:11.
II Thessalonians 2:11, “And for this cause God shall send them strong delusion, that they should believe a lie:”
I John 2:18: “Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.”
II John 1:7: “For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.”
Jude 1:4: “For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.”
