"Don't let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction."
â 2 Thessalonians 2:3-4
Quick Answer
The antichrist is a future world ruler described as the man of lawlessness who exalts himself above God and demands worship (2 Thessalonians 2:3-4), and as the beast who deceives the nations and persecutes believers during the tribulation (Revelation 13:1-8). Scripture guarantees his ultimate, total defeat at Christ's return (2 Thessalonians 2:8; Revelation 19:20).
A Figure With Many Names
The specific word antichrist appears only in John's letters, where John actually uses it to describe both a future individual and a present spirit of opposition already at work in the world (1 John 2:18, 2:22, 4:3, 2 John 1:7). But the figure popularly called the antichrist draws together several different biblical descriptions: Daniel's little horn (Daniel 7:8), Paul's man of lawlessness (2 Thessalonians 2:3), and John's beast rising from the sea in Revelation 13.
Paul's Man of Lawlessness
Paul gives one of the clearest descriptions in 2 Thessalonians 2. He warns believers not to be shaken by claims that the day of the Lord has already come, insisting it cannot happen until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction (2 Thessalonians 2:3). This figure will oppose and exalt himself over everything that is called God or is worshiped, so that he sets himself up in God's temple, proclaiming himself to be God (2 Thessalonians 2:4). It is hard to imagine a clearer description of ultimate, blasphemous self-exaltation.
John's Beast From the Sea
Revelation 13:1-8 fills in more detail, describing a beast rising out of the sea with authority given to it by the dragon, Satan himself (Revelation 13:2, 12:9). This beast receives a fatal-seeming wound that is healed, astonishing the whole world into following it (Revelation 13:3), and is given authority to make war against believers and to rule over every tribe, people, language, and nation for forty-two months (Revelation 13:5-7). The whole world, except those whose names are written in the Lamb's book of life, worships this beast (Revelation 13:8).
A Counterfeit, Not an Equal
It helps to understand the antichrist as fundamentally a counterfeit of Christ, empowered by Satan to imitate, in twisted form, the true King. Where Christ was slain and rose again, the beast has a fatal wound that is healed (Revelation 13:3, 12). Where Christ receives worship rightfully as God the Son, the beast demands worship blasphemously, propped up by a second beast, sometimes called the false prophet, who performs deceptive signs to compel allegiance (Revelation 13:11-15, 19:20). The imitation is deliberate; Satan has never had an original plan, only a corrupted copy of God's.
This counterfeit pattern extends even to how the antichrist rises to power. He performs signs and wonders, but they are lying ones, deceptive rather than genuinely miraculous in origin (2 Thessalonians 2:9-10), much as Pharaoh's magicians once mimicked some of Moses' signs before being decisively outmatched (Exodus 7:11-12, 22). Satan has always specialized in imitation rather than innovation, offering a shadow of divine power to those unwilling to submit to the real thing.
Centuries of Guesses, and Why Caution Is Wise
Believers across church history have proposed a long list of candidates for this figure: Roman emperors persecuting the early church, various medieval and Reformation-era rulers, and a long line of twentieth-century dictators and political figures. Every generation, faced with its own version of tyranny or global crisis, has been tempted to conclude that its own worst villain must be the antichrist himself. Every one of those guesses, so far, has been wrong. This pattern should produce real humility rather than cynicism about the doctrine itself; Scripture's description of this figure remains true and future, even though the church's track record of identifying him prematurely has been consistently poor.
Restrained For Now
Paul adds an important detail often overlooked: something, or someone, is currently restraining this figure from being revealed (2 Thessalonians 2:6-7), a restraint many interpreters connect to the ongoing presence and work of the Holy Spirit through the church in the world. This means the full, unveiled antichrist has not yet appeared in history, whatever various generations have speculated about specific rulers or figures. His appearing is a future event, not a description of any past tyrant.
A Guaranteed, Total Defeat
Whatever fear this figure's description might stir, Scripture never leaves him unanswered. Paul says the Lord Jesus will overthrow him with the breath of his mouth and destroy him by the splendor of his coming (2 Thessalonians 2:8). Revelation describes his final end plainly: captured along with the false prophet and thrown alive into the lake of burning sulfur (Revelation 19:20). No matter how powerful this figure becomes, or how long his reign of deception lasts, his defeat is already certain, decided before he ever appears. That certainty is meant to steady believers now, long before any of this unfolds: Christ has already won, and every enemy, however fearsome, is already defeated in principle at the cross (Colossians 2:15).
