Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour.
1 John 2:18
Revelation 13:1-8 The word “antichrist” is not found in classical Greek prior to the coming of Christ. It may be a word coined by the apostle John since he is the only one who uses it in the New Testament (1 John 2:18, 22; 4:3; 2 John 7). To describe someone who was against Christ or drawing attention to himself instead of Christ, one would attach anti (“against, opposite, instead of”) to Christos to create “antiChrist.”
John used the word two ways: to refer to the Antichrist (1 John 2:18, 4:3) and those who operate like the Antichrist (1 John 2:18, 22; 2 John 7). Like Satan and his demons, a satanically inspired individual who appears at the end of the age has satanically inspired emissaries who are doing his work at present. In truth, the antichrists that John warned against—anyone who is against the true person and work of Jesus Christ—are everywhere in the world. And like those to whom John wrote, we must be aware of their presence and deception (2 Corinthians 11:13-15).
Be alert and on your spiritual guard today for antichrists who deny and deceive.
When Scripture speaks of Antichrist it includes the whole duration of his reign.
