The apostle John left us with a guideline for discerning and understanding what it means to be of an “antichrist spirit.” Listen to his words here:

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. (1 John 4:3)

It is important to remember that the word “Christ” literally means Messiah.  When we talk about Jesus Christ as coming in the flesh we are saying that Jesus came down from above, He became flesh, and He is is the Messiah. There are plenty of people, in fact billions of people, who do not believe that Jesus is the Messiah, the One sent by the Father to this earth as the Messiah, Saviour and Redeemer. I have shared the gospel with many people who believe that Jesus was nothing more than a good man.  There are others, including the people of Islam, who believe that Jesus is a prophet, but not the Son of God because they believe that God has no Son.  The majority of Jewish people do not believe that the Messiah has come and are still waiting for His “first coming.” There are thousands of religions throughout the world who do not believe that Jesus Christ is come in the flesh and according to John they are of an “antichrist spirit.” John goes on to say this in another letter:

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. (2 John 1:7)

Here John now puts that same class of people into the category of deceivers and he tells us that there are many of them.  This is in agreement with what John declared in his first letter:

Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. (1 John 2:22)

If you deny the Son, then you also deny the Father.  It is a package deal.  We need to be aware of the hour in which we are living ladies and gentlemen, because John penned those letters nearly two thousand years ago.  Things have gotten much worse since then.  If God’s Word calls this deception and falsehood then you better call it the same thing if you have your sights set on heaven.  If you are of the mindset that these things really do not matter, then I tell you that you are already deceived.  It is important that we take heed to the words that John spoke all those years ago because it is a matter of life and death.  It is a matter of heaven or hell.
