The name "Antichrist" is only found in 1 John 2:18, 2:22, 4:3, and 2 John 7. The Apostle John was the only Bible writer to use the name Antichrist. Studying these verses, we learn that many antichrists (false teachers) will appear between the time of Christ's first and Second Coming, but there will be one great Antichrist who will rise to power during the end times, or "last hour," as 1 John phrases it.
The Antichrist will deny that Jesus is the Christ. He will deny both God the Father and God the Son and will be a liar and a deceiver.
