An antichrist is simply one who is against Christ (Jesus). As such, there were, are, and will be many antichrists.
The word antichrist only occurs four times in the Bible, all in John’s writings:
1 John 2:18, 1 John 2:22, 1 John 4:3, and 2 John 1:7.
Interestingly, antichrist does not appear in the book of Revelation, though the phrase, “the beast” is used often (as well as in Daniel’s prophecy: Daniel 7:11 and 19). Many consider the beast to be antichrist or the Antichrist. The idea of an ultimate Antichrist is perpetuated in pop culture and movies.
Key verse about Antichrist: Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son (1 John 2:22, NIV).
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 1,000-page website ABibleADay.com to encourage people to explore the Bible. His main blog and many books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
